I have installed the Visual Studio 2010 Remote Debugger on a Windows Server 2003 (x86) server, and am attempting to connect to it results in the following error:
Unable to connect to the Microsoft
Visual Studio Remote Debugging Monitor
named 'ServerName'. The Visual Studio
Remote Debugger on the target computer
cannot connect back to this computer.
A firewall may be preventing
communication via DCOM to the local
computer. Please see Help for
assistance.
I have checked my Windows firewall setting, and ensured file sharing is enabled on my local machine. I have ensured that DCOM is running on the server, as well as the debugging service. There are no actual firewalls involved that I know of.
What else do I need to change to get this to work?
I just ran into connectivity issue. The problem was the Client PC (my desktop) could connect to Remote Host running debug monitor, but the Remote Host could not send data back to my desktop.
Turns out that it was caused by the 'Profile' setup in Windows Firewall. The Firewall rule was being limited to 'Public' profile - but my desktop was connected to the local domain. Changing the setting to 'Domain' ensured the Remote Host could communicate debugging data back to Client desktop.
Check under Windows Firewall -> Inbound Rules -> Microsoft Visual Studio -> Advanced Tab.

Here are the steps I took to get remote debugging to work against an ASP.NET app. Not sure if you've done this already, hopefully something might help.
On my machine (call it DEVMACHINE from now on) I shared out the folder that contained the remote debugger (msvsmon.exe). On my machine, it was located at C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger\x86. I called the share msvsmon
On the server, I opened Windows explorer and navigated to \\DEVMACHINE\msvsmon, and ran msvsmon.exe (This opened the Visual Studio Remote Debugging Monitor)
On DEVMACHINE, I started Visual Studio 2010 and opened the solution that represents the application I'm attempting to debug.
In Visual Studio, clicked Tools > Attach To Process...
Entered the server name in the Qualifier field, then double clicked on the w3p.exe process that was in the list.
I then placed a break point in the location I wanted to start debugging
Couple things to note: The code deployed to the server was a Debug Build, the pdb files were there, along with the binaries. I had full admin rights on the server. No tools were installed on the server, I simply ran the exe that was located on DEVMACHINE. I did not have any firewalls between the DEVMACHINE and the server. And, both DEVMACHINE and the server are on the same domain.
Hope that helps.
I kept getting the same error listed above, and after trying all of the other answers, the problem turned out to be that DCOM was disabled on my development machine. The problem was solved by enabling DCOM using the instructions from this technet link.
I am using local DNS so I can test websites before they go live (by editing my hosts file).
I have a specific IP assigned by my router at home and at work.
i.e. dev.example.com is mapped to 192.168.1.123
When my machine changed to a different network without me realizing it could no longer reach the debugger and so I got the error.
Pretty obscure situation I had to get this error, which no amount of rebooting or recycling IIS will fix.
I had the same problems with the debugging service. The debugging service was starting automatically but I could never connect. I even turned off the firewall completely and that didn't help either.
Try running the debugging monitor (as opposed to the service) and connecting to that. You can find it in the start menu.
Confused about the difference between the monitor and the service? So was I. See http://social.msdn.microsoft.com/Forums/en/vsdebug/thread/afc80afc-c8eb-4831-915a-1edb8d188f98
Same problem here. My reason was that Trend security was enabled in the local computer, and it was blocking the firewall. I could not stop it because I needed a password, so I just deleted all the Trend processes, and it seemed to work fine. So you could check if some antivirus is enabled that is blocking the access.
I also needed to add devenv.exe to the Allowed Programs in the Windows Firewall in the local computer, and set its policies.
Below is a quick step to set up Visual Studio Remote Debugging Monitor on Visual Studio IDE.
Open Programs > Microsoft Visual Studio 2010 > Visual Studio Tools > Visual Studio 2010 Remote Debugger Folder.
A Windows Explorer shows the 32 and 64-bit versions of the Remote Debugging Monitor.
Copy the respective ver that matches remote server (e.g. x64 machine use X64 folder & x32 machine use X86 folder) to a folder on
your machine.
While at the console on your remote machine, go to the folder and start msvsmon.exe.
Go to Tools > Options and change the Authentication mode to No Authentication and check the box Allow any user to debug.
From your development machine, on Visual Studio, go to Tools > Attach to Process.
Change the Transport to Remote and the Qualifier to the name of your remote server.
You should now see the executable, which you want to debug on that list. Select the process you want to debug and click Attach.
You may now debug the code while it is running on the remote server.
Just remember to turn off Remote Debugging Monitor at the remote server once done.

I tried using IISExpress to launch my web projects in Visual Studio 2015. I have both a RESTful service project and a front end website. Neither one will launch and after drilling into the diagnostics in Internet Explorer I find the error message
The remote device or resource won't accept the connection.
I have tried resetting Internet Explorer and there is no proxy server that might be interfering with the connection.
A) Check to make sure that IISExpress is running. First, start your project in Visual Studio, then click the Start button and search for 'Resource Monitor'. Expand the 'Network' section and look for IISExpress. You could also use Ctrl-Alt-Delete and choose Task Manager to see whether IISExpress is running. If it's not there then there is a problem with IISExpress and it's not even running. In this case you can work around the issue by configuring the web project to run in IIS.
Make sure IIS is set up on the machine
How to enable IIS on Windows
Configure Visual Studio to use IIS to run the web project
Use Local IIS as a Web Server in Visual Studio
B) Check the version compatability of IISExpress with Visual Studio. IISExpress 10 does not work with VS 2017, for instance.
C) There are any number of reasons why IISExpress night not be starting

When I want to debug my web project on local iis I get this error message. First I tried to debug an Umbraco project and I got the message below. First I thought it was because of Umbraco but a new empty web project gave the same error message.
Unable to start debugging on the web server. The Visual Studio 2017
Remote Debugger (MSVSMON.EXE) does not appear to be running on the
remote computer. The may be because a firewall is preventing
communication to the remote computer. Please see Help for assistance
on configuring remote debugging.
My configuration in Visual Studio 2017:
Local IIS
Project URL: http://my.domain.dev.nl
Virtual directory has been created successfully. Of course I tried some things before asking.
I tried to restart the Remote Debugging process.
I tried this command: devenv /resetuserdata.
I started a complete new project.
I changed debug CPU from any to x86 and x64 also.
If I choose for IIS Express I can run my project without any issues.
Someone any idea?
Edit:
Another thing to mention is that I have tried to ping the local address http://my.domain.dev.nl and I got a reply from another ip. Of course I checked my IIS bindings but everything is ok.
When I open my existing solution in Visual Studio 2012 professional, I got the above error. This used to work but something messed up after the computer is rebuilt.
I have installed Visual Studio 2015 Community and can connect to the same
collection correctly.
I also tried to use a browser to connect to the same collection. It works fine also.
Cleaning all files in AppData\Local\Microsoft\Team Foundation\4.0\Cache does not work.
It should not be a firewall or proxy issue since Visual Studio 2015 works.
Anyone knows what is wrong with Visual Studio 2012 and how to fix it?
Edit:
This error can happen with later versions of TFS:
Team Foundation Error
TF400324: Team Foundation services are not available from server TFSServer\DefaultCollection.
Technical information (for administrator):
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond xxx.xxx.xxx.xxx:443
According to this blog the solution is (and Yes it worked for me)
Close all instances of Visual Studio
Open the Task Manager and check if any TFS Services are running. Select each of them and click on End Process Tree (in my case I did not find any of them to End)
Browse to the folder %LocalAppData%\Microsoft\Team Foundation\
and then select the folder with your TFS version and go inside the Cache folder.
for example, in my machine the path was %LocalAppData%\Microsoft\Team Foundation\7.0\Cache and it should be the same on your machine with the difference of the TFS version folder name.
Delete everything in that Cache folder.
Start Visual Studio and build the project
I got this error in TFS2017. For me the problem was a Self-Signed Certificate.
Open the TFS URL in IE and you will see a Red Address Bar:
Click the "Certificate Error" in the address bar:
Then select "View Certificates":
If clicking "View Certificates" doesn't work, right click on page > Properties > Certificates.
If the Install Certificate button is hidden to make it visible you will have to Open Internet Explorer Options > Security > Sites > type the TFS server URL > Tick Require server verification > click Add. (If the dialog is disabled see the guide Trusted Sites Dialog is Disabled at the end of this answer).
Once you have the install certificate button available, select “Install Certificate”.
This will launch the Certificate Import Wizard. Make sure to Choose the option “Place all certificates in the following store” and select browse.
Select Trusted Root Certification Authorities and click Ok.
Click Finish on Completing the Certificate Import Wizard:
Click yes on the security warning to install the certificate.
=================================================
Trusted Sites Dialog is Disabled
You can check to see if the site is Trusted, on Windows 7 the path is:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMapKey
The key should contain several string values with a name indicating the URL and numeric data indicating the zone, one of the following by default.
0 = My Computer
1 = Local Intranet Zone
2 = Trusted sites Zone
3 = Internet Zone
4 = Restricted Sites Zone
If the TFS site is not listed in the registry then add it manually. Restart Visual Studio and try to connect to the TFS server again from Visual Studio. Once you can connect you can also remove the TFS server from the Connection List. I suggest removing it and adding the FQDN url which will most likely already have a Trusted Site rule.
Edit
Hit this again. This time it was caused by a problem with a network card that was replaced on the weekend by our telecommunications provider.
This issue is happening when server is not responding, In my case server hosting TFS was down, we restarted and get connected.
Try clear both local TFS cache and Visual Studio Cache
clear visual studio cache under
%APPDATA%\Microsoft\VisualStudio
clear TFS cache under
%LocalAppData%\Microsoft\Team Foundation
...better late than never...
I just had a user run into same error TF400324 connecting VS2012 to TFS2015 (hosted in a virtual private cloud). TFS Web Access worked fine for her, but Visual Studio 2012 UI was stuck in offline connection.
FIX: She managed to get VS connected again after clicking Team Explorer > Connect | {TeamProject}, Then select desired Team Project below the TFS Server connection (see screenshot attached).
NOTES:
I suspect clearing client-side TFS cache might also fix, but all VS instances would need to be closed then "Connect to Team Project Connection" re-established. Just disconnecting and reconnecting VS to TFS did not clear the "offline" state.
Error she saw was in VS output window:
This solution is offline. [Team Foundation Server: {//TFS Collection URL}]
The solution was offline during its previous session and will remain offline.
TF400324: Team Foundation services are not available from server .
Technical information (for administrator):
Page not found.
NOTE: I recently moved TFS to different domain requiring SSH connection and localhost port mapping. I have users going offline much more frequently due to different proxy routing depending on whether they are at work or connected more directly to the Internet.
For me the fix was simply running Visual Studio (2010) as an administrator.
In my case, my company VPN my Host machine was connected to was preventing me to access the tfs on a VirtualBox VM, returning this exact error message.
We solved it by adding a specific exclusion to ESET / Kaspersky AntiVirus for the devenv.exe
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"
Its been working great ever since.
I get basic idea from this link
Soluton for me was to run the standalone TFS installation. This is for 2017, but worked to fix my VS2019.
https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=TeamExplorer&rel=15
Bit of background...
I'd been having this issue since 2017. Tried all the usual suggestions on here, cache clearing, config file editing etc. but would always have to come off my organisation's network to check code in, as it was proxy related. TFS was trying to connect to a proxy server ip that had been decommissioned, no one from the service desk could work out why. Couldn't find any reference to this old ip in any config files.
Installed VS2019 hoping it would solve the issue but it persisted. Eventually I thought of trying to uninstall it as a component and re-installing it. Couldn't find a way to do that but in my search I found the standalone installer for Team Explorer, albeit for VS2017.
After installing, I ran this, opened up Manage Connections in the Team Explorer connections page and did what I needed to connect to the repository from there. Worked first time. Closed Team Explorer 2017, opened my VS2019, and everything seemed fine in there as well.
Amazed my problem is finally solved!
This error is usually related to the TFS cache. Before you clear the cache folder, please make sure you have closed all instances of Visual Studio and also try to open Task Manager and check if any TFS Services are running. Select each of them and click on End Process Tree.
And also clear the server cache Server cache, the path like C:\ProgramData\Microsoft\Team Foundation\Web Access
Then restart Visual Studio and run as Administrator Mode.
More details you can refer this blog (archived version at the bottom) and also could try the better fix.
Note: Make sure you are working on a different workspace rather then VS2015's.
For me it was the windows firewall causing this problem : TF400324 The underlying connection was closed.
I have read this question and this page linked to in the question, as well as dozens of other articles about debugging asp classic with VS but it's still not clicking for me.
I am using VS 2010. The files I want to debug live on a remote server. I have installed the Remote Debugger on the server. I opened the website and attached to the w3wp.exe process on the remote machine. I created some breakpoints but I am still getting "The breakpoint will not currently be hit. No symbols have been loaded for this document" on those breakpoints. Is that the problem or is that a symptom of a larger problem with what I am doing?
First, by default, when you open a web site in Visual Studio, you're opening it via the file system, not via IIS. If this is the case, then Visual Studio uses the internal Cassini web server, rather than IIS.
The Cassini web server does NOT run classic ASP. IIS does. So the first thing you need to do is figure out how to debug in IIS.
It should go without saying, you need to have IIS installed on the machine you're working with, and have the web site you're debugging set up the same as it would be on the server. (so you should be able to run http://localhost/somepath and be able to see your site)
You also need to attach to the running process of Internet Explorer. There's a link to that as well.
Next, you need to get Visual Studio to attach to IIS and execute the web site rather than use the built-in web server and enable debugging.
That's covered here: This topic is no longer available (which is the first child link of the page you liked to in your question here.
From there, you should be able to follow the remaining links and get up and running.

This article takes you through it step-by-step.
Debugging Classic ASP ( VBScript ) in Visual Studio 2008
I've just had this problem when trying to debug a classic ASP application in VS2012.
There's no need to copy PDB files, because there aren't in this kind of projects, so follow this steps:
Be sure that ASP compatibility is turned ON in your IIS installation (Control Panel -> Enable/Disable Windows features -> Internet Information Server). You can install all features if you want to be sure.
Access to the IIS administration.
Locate your WebSite, then access the ASP configuration.
Find "Debugging properties" and then enable client and server debugging. You can also enable error sending to the browser.
After that, just attach the VS2012 debugger to the "w3wp.exe" process. DEBUG -> Attach to process....
This will work for local debugging. If you want to do remote debugging, you must prepare the remote server to allow remote debugging (TIP: Use the same user in both, server and your machine, and be sure it has enough privileges). For more information take a look at:
Installing the Remote Tools
Debugging Classic ASP ( VBScript ) in Visual Studio 2008
From time to time I get the following error when starting the debugger in Visual Studio 2008 SP1:
The network connection to MYCOMPUTER has been lost. Debugging will be aborted.
I have several projects in the solution configured as startup projects. Some of them get started when the error occurs, some won't.
Any ideas?
Update:
- Visual Studio runs on a 64 bit machine (Win7)
- The application uses MSMQ (private queues on localhost)
The fix for me was deleting all my breakpoints. Evidently, an update from source control corrupted some pre-existing breakpoints.
What's likely happening here is that you are using remote debugging on your application. Some error during startup is causing that error message.
Can you give us a bit more information on the applications.
Are you expilictly using remote debuggging?
Are their any resources being used on MYCOMPUTER via some remote operation?
Are you runnig projects off of a share?
You may be implicitly using remote debugging if you are debugging a 64 bit appliction. Visual Studio runs as a 32 bit process and uses remote debugging under the hood to debug 64 bit applications.
For anyone stumbling on this post, I fixed this problem in Visual Studio 2015 by uninstalling Agents for Visual Studio 2015 on the remote machine.
For some reason it conflicted with the remote debugging process but I couldn't figure out why exacly. I found this by meticulously comparing a working remote machine with one that gave me the error and fixing every difference that I could find.
Check debug properties on your startup projects, there might be remote debugging configured. (Debugging/Remote settings)
Disable "Use Managed Compatibility Mode" option in Tools - Options - Debugging. It solved this problem in my case.
Add powershell rule as Admin. (You may need to change the file path to match)
New-NetFirewallRule -DisplayName "msvsmon" -Direction Inbound -Program "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\Remote Debugger\x64\msvsmon.exe" -LocalPort 4026 -Protocol TCP -Authentication Required -Action Allow
Other stuff I did:
add the following to your hosts file in C:\Windows\System32\drivers\etc
127.0.0.1:4026 YourComputerName # hostname
127.0.0.1:4026 localhost
More stuff I had to do:
open C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\Remote Debugger\x64\msvsmon.exe
check if the port is 4026 and also click on the Permissions button and see if the Admin and Yourself have permission to debug
also open C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\Remote Debugger\x86\msvsmon.exe
and see if the port is 4026, also check Permission to debug
Since I'm using HitmanPro antimalware/antiransomware software, I added all the *msvsmon.exe and main Visual Studio executables to the exceptions including the services (*msvsmon.exe files which don't have a UI). I also added the entire Visual Studio Install Folder to Windows Security as an exception. Therefore make sure you add these locations and files to your relevant antivirus, antimalware, antiransomware programs as well.
Almost gave up... but never do that... spent 3 days figuring this out and yet MS has pages and pages of stuff that will just probably confuse you.
