I have two web sites run in IIS on a Windows 2019 server. I've been able to debug both by typing "stop" in the VBscript and it pops up a dialog box that says a "script breakpoint" occurred and which debugger do I want to use. I select Visual Studio 2022 and away we go.
Until now... all of a sudden, I can't debug one of them (development) but I can the other (production). There is NO ERROR, it just doesn't pop up the debug dialog box. I've changed a few pages in dev (asp and aspx) but nothing that should affect any settings. Both are on the same server and the only two web sites in IIS. They "should" be mirror images of each other when development is moved to production.
Compared IIS, ASP, Debugging properties and they are the same.
Run iisreset and rebooted numerous times.
Made sure web.config's are the same.
Started VS and attached to the development w3wp.exe... just ignores the stop command.
Put stop in a second page of the root of each web, production stops, dev doesn't
Checked registry - Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug
Debugger string is "C:\windows\system32\vsjitdebugger.exe" -p %ld -e %ld -j 0x%p
Coded a divide by zero in each page
production opens debug dialog and then gives HTTP Error 500.19 - Internal Server Error
dev shows white page with absolutely nothing in view source
I'm reasonably sure this is not a VS thing since both webs are built in the same VS... and actually the default page I'm putting the stop in was "hand" built, not in VS and the only pages in the root folder. So it seems like some setting in IIS, but what one?
Web.config is minimal for both:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<directoryBrowse enabled="true" />
</system.webServer>
</configuration>
Any direction here would be greatly appreciated.

I have to debug a classic asp site being served by IIS 7 (windows 2008).
How can I do this? I have only worked with ASP.NET.
From an MSDN blog post: http://blogs.msdn.com/mikhailarkhipov/archive/2005/06/24/432308.aspx
Here is how to make ASP debugging work:
Enable ASP debugging on the server. (I also added DEBUG verb to the asp extension, but I am not sure if it is required).
Open classic ASP in VS 2005.
Set breakpoint.
View page in browser or run without debugging.
Debug | Attach to Process
Locate IIS ASP worker process (w3wp.exe on IIS6) which exposes x86 and Script and attach as Script.
From eddiegroves comment below:
Regarding Step #1 in IIS7 - IIS > ASP > Compilation > Debugging Properties > Enable Server-side Debugging
I realize this is old, but thought I'd reply to help others since I was looking something else up.
You can use Visual Studio to debug Classic ASP.
If you're running a local copy of IIS, just attach the debugger to the w3wp.exe process and you can set breakpoints, add variables to watch windows, etc.
If you have more than 1 website, it's helpful to run each in a separate application pool, and you'll be able to identify different w3wp.exe process in the Attach Process window.
Just choose "script" as the debugger type. If you're running IISExpress, then the iisexpress.exe process is the correct one to attach to.
I've found that a useful setting to enable is found at the server level under ASP > Compilation > Debugging Properties > Send Errors To Browser. Set that to "True".
This may not be appropriate under all circumstances (e.g. for an internet-accessible site).
Built in classic ASP debugging is pretty poor. I put together this ASP include class which works with Firebug+FirePHP. It allows you to log values (including strings, multi-dimensional arrays and even objects created with json.asp) to the firebug console and view ASP's built in collection objects which can help (particularly with Ajax where you can't output debug data without breaking the json response.) Ajax script load times and errors are automatically logged for quick viewing.

This is the way I figured it out:
Put a stop (write stop) on the place where you want to hit the debug point. Then run the application on browser. When the execution comes to stop it will open up debug popup asking do debug with Visual studio (a VS version must be installed). Then it will ask to attach the process and you can use f10, f11 to go step over and in. You can see the data using add watch.
I use the following (which I got from somewhere online) to write to a log file. I would prefer a method for writing directly to Console in Firefox or Chrome, but this works pretty well for me.
NOTE: "timestamp" is a custom function of mine. You can probably guess what it does, and probably roll your own. ;-)
function error_log( message )
dim objFSO, objLog
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objLog = objFSO.OpenTextFile( "ASP_errors.log", 8, true)
objLog.WriteLine "[" & timestamp & "] VBS Message: " & message
objLog.close
set objLog = nothing
set objFSO = nothing
end function
host your site on IIS server.
enable remote debugger on IIS server.(follow this tutorial)
import the source code into visual studio.
install remote debugging tool from here
In the remote debugging tool select tools-> options -> no authentication for all users.
Go to visual studio and attach to process w3wp.exe.
if cant see the process (w3wp.exe). Open the website link in browser and select show for all users
now u will be able to see the process and attach.
Dont forget to put a debugger in the application :-)
I am attempting to run an application in IIS8 that has the following in the config:
<modules runAllManagedModulesForAllRequests="true" />
IIS8 is giving me an error that says...
This configuration section cannot be used at this path. This happens
when the section is locked at a parent level. Locking is either by
default (overrideModeDefault="Deny"), or set explicitly by a location
tag with overrideMode="Deny" or the legacy allowOverride="false".
I'm guessing by the error and a quick SO search that there is some higher level security setting that's preventing that line from being allowed. Any ideas?
I've solved the same problem by installing the window features "Internet Information Service/World Wide Web Service/Application Development/ASP.NET x.x" in the Control Panel of Windows8. If you want to setting on Windows Server 2012, the following link gives you hint.
http://www.iis.net/learn/get-started/whats-new-in-iis-8/iis-80-using-aspnet-35-and-aspnet-45
hope that it works out.
For those of you running Windows Server 2012 the Application Development features are found at
[] Server Roles
[] Web Server IIS
[] Web Server
[] Application Development
[] ASP.NET x.x
When you select the .NET version it will ask if you want to add Extensions and other features. I just said yes, but you may be able to get away without installing those.
its hard to give a specific answer here, but the basics of it are that you need to look at the machine.config for the box you're running on. find the system.webServer node and look for the 3 tags/attributes its referencing in the error. chances are you'll find something that is marked as not overridable (allowOverride="false"), but i've not messed with windows 8/server 2012 yet, so i don't know what the machine.config looks like.
You can unlock the section via the IIS UI per https://serverfault.com/a/516921/137255
Open IIS Manager
Click the server name in the tree on the left
Right hand pane, Management section, double click Configuration Editor
At the top, choose the relevant section based on the offending item's XPath; i.e. system.webServer/modules for this example.
Right hand pane, click Unlock Section
I want to debug my application by VS but when the application should run, it should have url like: http:localtesting.com instead of localhost. I already have localtesting.com in my host file so directly putting that url in my browser opens my IIS default directory page. How can I make my VS to run on that url while debugging? Where should I put that url?
Edit:
Putting the url in custom web server textbox and running the solution I am getting :
Set it to "Use Custom Web Server" and put your URL into that box.
Edit: 'The unable to debug..' error message is probably a separate issue. Can you debug a brand new site that you can create just to test?
A few things can cause that error. For example, the URL Rewrite module: Unable to start debugging on the web server. Could not start ASP.NET debugging VS 2010, II7, Win 7 x64
As #SteveHobbs said, set it to "Use Custom Web Server and put your URL into that box. Just underneath that section, there should be another section labelled "Debuggers".
Put a tick into the checkbox next to ASP.NET and save the properties.
When you want to debug, go to the debug menu within VS and choose "Attach to Process...".
If you are using IIS, look for the process called 'w3wp.exe' and choose that. After a bit of crunching, perform whatever actions you need on your web app and you will see the debugger land on your breakpoints and so on.
I cannot start my website from Visual Studio 2010 anymore.
For a few days I cannot start my project in a web browser using F5. When I open my web application directly by typing the same url 'http://localhost/Default.aspx' everthing works fine.
When I run the project (F5) a new webbrowser starts, but after a few seconds it is stuck and Visual Studio gives an error dialog:
Microsoft Visual Studio
Unable to start program 'http://localhost/Default.aspx'.
OK
When I run the project in release mode it gives an extra error:
Microsoft Visual Studio
The following module was built either with optimizations enabled or without debug information:
C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\6552bec6\694bce32\assembly\dl3\8c9bd8d8\fb1d75cb_af26cc01\[name].Presentation.DLL
To debug this module, change its project build configuration to Debug mode. To suppress this message, disable the 'Warn if no user code on launch' debugger option.
OK
I have already repaired, removed and reinstalled Visual Studio 2010, I've tried using different browsers (including Chrome and Firefox), used different aspnet_regiis.exe options, etc. etc.
Nothing helps, and yeah now I'm stuck pulling hair out of my head ...
Anyone any idea how to solve this?
Does it work if you start it with [CTRL]+[F5] which runs without the debugger?
If so, then you have an issue with the debugger auto-attaching to the web server. I would check that debugging is enabled for your web project - a warning that usually crops up automatically from VS when it detects that a project is not built in Debug mode.
This is not as simple as switching the project configuration over to Release, because the DLL that the debugger is moaning about is one of the dynamically generated ones originated by Asp.Net itself.
Typically you should have, in your web.config:
<configuration>
<system.web>
<compilation debug="true" >
</compilation
<system.web>
<configuration>
(Along with any other stuff in <configuration> and <system.web> nodes).
There's also the possibility that Asp.Net debugging is not, for some reason, enabled.
Check out this msdn article on debugging asp.net applications in VS2010 for more information.
Note that if this is VS010 express, then you won't be able to debug - as confirmed by the aforementioned link; but since you way it used to work then I guess that's not your problem.
Update
Since that hasn't worked - you can try emptying the Temporary ASP.Net files folder. Easiest first is to do an iisreset. Then navigate to C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and delete everything in it. I've had issues in the past where the Asp.Net binaries don't get refreshed and so when I'm debugging it moans that the files are out of date.
Change the View Browser to another browser. Run the view in browser or debug, then change back to original browser should work after that.
Had same problem, answer for me was to remove Avast Free AV. Everything worked for a year with avast free up until a week or so ago, uninstalling it fixed the problem.
I had this exact problem with Visual Studio 2008. The solution was to set the default web browser that VS uses to a real browser (e.g. IE) and not the "Internal Web Browser".
Right click on an ASPX file in your project and select "Browser With...". This lets you select the default browser to use when you select the "View in Browser" option and for when you debug/run the app (this is key).
Select your favourite browser (i.e "Internet Explorer") and click on "Set as Default". Do not pick "Internal Web Browser".
Debug away! Your app should come up in your browser now and debug as normal.
the solutions for me is to test with 127.0.0.1 in place of localhost. and all goes well for.
so the problem come from the host resolution name, to solve it please proceed like :
open cmd and then tape : %systemroot%\System32\drivers\etc\
open hosts file with notepad and the look for localhost ligne(you'll find 0.0.0.0 befor it )
change the 0.0.0.0 with 127.0.0.1 at all lignes with localhost .
I solved in this way:
Right click on a aspx page
Browse with set internal browser as default
Remove the previous default browser
Add %programfiles(x86)%\internet Explorer\iexplore.exe
Set this choice as default
For me I just did a Build /ReBuild on the project level and it started working!!!
I had the same problem. When I debug my code it says:
Unable to start program 'C:\homework.exe'. this system cannot find the file specified."
I'm using Microsoft Visual C++ 2010 Express but when I made a new project by the following steps:
Open C++:
Press new project
Press win32
Press win32 Console Application
Rename it
Click next
make sure: that the application type is console application
additional options: empty project*
Press Ctrl+Shift+A
In Visual C++/Code section press C++ File (.cpp)
rename it and press add
It works fine with for me now.
Please set your page name e.g Default.aspx revert to parent in IIS configuration
I'll share my experience with this same problem. This is not a solution, but someone may be able to figure out the problem from my particular experience.
I've been having this same problem for a few weeks now. (I don't know what changed on my system.) I do not run as local admin, because we are not allowed to have admin privileges on our PCs where I work.
Until today, I could expect F5 (Start Debugging) to start up a new local VS web server, open an IE window, and then issue an "unable to start program http://localhost:nnnn/Login.aspx" and "access is denied" error pop-up. If I closed the IE window, waited a few seconds, and then clicked F5 again, it usually started up my web app in debug mode just fine from that point on.
But today, that all changed. I did not change any configuration on my web app, which has been running fine, but I did add a couple of more classes to one of my subprojects. At this point, I could never get past the "unable to start program" message. I could run my app without debugging, but that was rather pointless. I even tried attaching to a running (non-debug) IE process, but that did not work.
Finally, I modified some of the properties in the WebAppName >Web >Servers screen. Specifically, I enabled "Specific port" for a specific HTTP port (which VS had been using all along), and I disabled "NTLM Authentication". I also enabled "ASP.NET" in the Debuggers section. Some of these I first clicked, then unclicked, then clicked again, saving in between each click.
This time, running with debug (F5) worked.
After running several times, I still usually get a "unable to start" error the first time after a recompile, but I can still usually get a debuggable running app to start after the second or third try. At least I'm back to where I was yesterday.
I suspect it has do with VS reloading its execution profile, and also probably something to do with permissions (since I cannot run as admin).
I'm using VS2012 with an ASP.net app that was written using VS2003... I've tried everything to get the IE page to open automatically when I select F5, or even Ctrl+F5... Haven't been able to get anything to work... However, I have stumbled upon a very poor work-around. When I select debug and I get the 'Unable to start program...' msgbox... I noticed that on the icon-tray I get a msg saying local-host has started
You'll notice a picture that the msgbox is pointing to:
Well, if you right click it, you get three options:
When you select the first: 'Open in Web Browser', it will open IE with the page your working with...
Like I said, it's a very poor work-around... but it works. This isn't an issue when I select debug using 'Chrome' or the page-inspector... But they have their own issues.
Try to turn on Bypass proxy for local addresses.
First you can go to your browser settings-> Change proxy Settings-> Connection-> Lan Setting and just check bypass proxy for local addresses.
If this solution don't work then also copy the following code check your web.config file for settings to bypass firewall:
<system.net>
<defaultProxy>
<proxy usesystemdefault="true" proxyaddress="http://proxy:port" bypassonlocal="false" />
</defaultProxy>
</system.net>
I easily resolved this problem by enabling script debugging in the browser.
When I ran into this problem (using IE 11) I noticed that iexplore was open about a hundred times in the task manager. After killing them all I was able to open my project just fine.
Since then, I have made a .bat file with this code:
taskkill /F /IM iexplore.exe /T
so now I just run the .bat when I get that error.
(alternatively you could run that code from the cmd)
I just ran into this problem in Visual Studio 2013. I had to enable Anonymous Authentication.
Click on the project node in solution explorer.
Hit F4 to show the properties window.
Change the Anonymous Authentication option to Enabled.
UPDATE: navigating to the process via menu:DEBUG / Attach Process / iexplore.exe shows "Automatic: Silverlight code". i.e. VS 2010 already attached to the process. Why doesn't it go to debug view?
I have a frustrating debug behaviour going on on my laptop which I'd like to fix. I was following along with the demo called Silverlight TV 46: What's Wrong with my WCF Service?
On my computer, I noticed that putting throw new ArithmeticException() in the RIA service causes the just-in-time debugger to get involved (a bad thing -- I want VS). I can put a break point on the the throw new ArithmeticExpression() line, and VS stops as it normally does. Press F10, and I still get the just-in-time debugger kicking in.
On Yvor's computer (the presenter in the Ch 8 link above), the visual studio debugger kicks in instead of the just-in-time one. What am I doing wrong? Could having Redgate Reflector installed previously have caused this (it is gone now).
ERROR:

I've spent several hours looking for a way to solve this.
Browser is IE9 / Silverlight 4.
Previously, I started starting the silverlight app directly via the VS2010 environment... but then decided to get more deployment compliant (again).
http://msdn.microsoft.com/en-us/library/cc838267(VS.95).aspx
Down the bottom they mention repairing from control panel / VS2010. Did that. Waited for ages, made coffee, did something else. Finally complete. Problem sill there. Included this step just-in-case the fix is cumulative (you get superstitious after a while with these things).
I then deleted zap files, switched startup page from html to the aspx one. Wired aspx to the xap (it wasn't pointing to the /debug/ folder). [note: looks like you can remove the debug via Silverlight Project / build / Output path: Replace Bin\Debug\ with Bin. With Silverlight I feel that the relative Uri path should match up to your html / aspx files no matter what -- wheather you are in Debug or Release.
project properties / Web / Specific Page
debugging works again!
Did .html stop debugging? Casual inspection reveals the same javascript stuff firing up Silverlight. On the surface it looks the same. hmmm. I guess it isn't.
... here are a few extra things to look at for those who still have issues (I may as well list them
while they are fresh in my mind).
project / properties / Web / Debuggers: I now only have Silverlight checked. ASP.Net is not checked any more. (Not sure if this influences my result at this stage)
make sure your web project points to the silverlight project in project / properties / Silverlight Applications. This ensures that the silverlight project's binary "xap" is copied to a folder within the Web Site / Web App. Note: hitting the add button reveals a destination folder (should be ClientBin).
Your build configuration will add an additional sub foler e.g. debug.
Make sure your .aspx or .html files have the right path. For me, I just included the .ClientBin/debug/ folder. I don't think this is deploy friendly, so I will search for a better way later.
IE9 settings.
[X] Disable script debugging.
[X] Disable script debugging (Other)
[ ] Display notification about a script error
[ ] Show friendly HTTP error message
Again, unsure if these later setting have an impact.
Lastly, there's something that I forget about sometimes. Be sure to check Debug VS2010 / Exceptions / Common language Runtime. This ups the ability to catch exceptions.
I had a similar problem, but the above did not resolve it. However, starting the application without debugging (Ctrl-F5) and triggering the exception would allow me to select the Visual Studio instance that I started the application from. Amazingly, I got a sensible stack trace and resolve the problem within a few minutes.
