I am attempting to setup a remote profiling session with a server. I have downloaded the latest version of Zend Debugger, and have installed it on the server with the following setup - http://puu.sh/3ezyh/39247f2f15.png . With my local machine, I have setup a putty session to the remote server, and forwarded port 10137 as per the KB article listed on zend.com.
I am able to debug the remote server without a problem, however when I goto profile the page, the page will process, then a dialog will pop up with a "Waiting for the debugger's response" message. After approximately ~20 seconds, I get the following error: http://puu.sh/3ezDk/57f6dc1bb5.png .
However, there will be profiling information displayed , as well as execution statistics, but no execution flow, almost like it's getting part of the data but not all of it.
The page in question does have anywhere from a 20-30 second page load (which is why I'm tyring to profile to find the problem.)
The only error I can find is in the server's error_log, which just says "[Zend Debugger] Cannot send message"
Is there anyway to diagnose why I'm not getting the complete response?
I wonder if it is getting your IP address and trying to send directly to it instead of over the local forwarded connection. You might need to set your host IP to 127.0.0.1 as the address like in http://screencast.com/t/7lheaOlx. If that doesn't work I would say do a
tcpdump port 10137
And see what you can see. Also, depending on your local OS you may have a firewall blocking access to your instance of Studio.

I am getting the above error message in production when trying to call the AddImageUrl section of ABCPdf (version 10). This started occurring yesterday just after midday my hosting provider assures me nothing has changed I am the only developer on the project as was working on something else entirely.
The URL provided in the stack trace can be accessed in IE on the web server without any error messages (including SSL). There is also a UAT environment on the same web server in which the PDF works, the UAT environment is identical in code and application pool settings, the only difference is the web address and database.
The HTML the PDF is calling can take a little time to come up on first load. Given that data is different I have increased the timeout from 15 seconds to 2 minutes.
I have arranged a reboot to see if that fixes it, but I have run out of things to check.
Edit: I did think of one further check, could I add the image of a page not on the site (https://www.google.co.uk/), doing this resulted in the same error so it appears not to be a blocking issue on the worker process.

Edit2: switched to the gecko engine and it is now working.
You can sometimes get this error if the web browser within Abcpdf cant access the URL.
On the webserver add the URLs directly to the local machine hosts file
C:\Windows\System32\drivers\etc\hosts
The entry should look something like this
127.0.0.1 example.com
I have a windows 16 machine on AWS. I installed Cygwin on it so that I can connect it as a jenkins slave. But once I connected it as a slave, I am NOT able to MSTSC/RDP into the machine. I can still access the machine via ssh/cygwin.
( I repeated the process several times and ended up losing rdp connectivity everytime )
This is what is actually happening now :
The EventLogs on machine are saying that logoff instructions are being initiated by the RDP client.
RDP client is saying "The disconnection was initiated by the user logging off their session on the server"
Visually, if seems like the remote connection was setup for a split second. Then it vanishes.
So, I believe that somehow my Administrator account is not able to maintain the session. It's getting disconnected as soon as it connects.
Can you suggest me which settings should I debug into ? I am able to extract a few details from my machine using ssh, but I can't explore all the settings.
If you are familiar with this behaviour please suggest me what settings might be reponsible for this.
Addition info:
If I restart my ec2 , it will never come back because a status check starts failing
I am able to telnet to 3389 port. So I guess, firewall rules are not an issue.
I have tried various RDP clients, on MAC as well as on Windows.
I found this in event log (ProviderName: Microsoft-Windows-RemoteDesktopServices-RdpCoreTS) on my remote windows machine:
5/10/2019 3:13:44 PM 103 Information The disconnect reason is 12
.

.
5/10/2019 3:13:43 PM 228 Warning Disconnect trace:CUMRDPConnection Disconnect trace:'calling spGfxPlugin->PreDisconnect()' in CUMRDPConnection::PreDisconnect at 4477 err=[0xc], Error code:0xC
It turns out the my problem was occuring due to some cleanup utility deleting up the system files required for mstsc.
Everything started working fine after I switched off the cleanup utility.
Thanks for the help though.
Issue: When running a load test from my client, with a remote controller on a second machine and a remote agent on a third machine, I receive the following error
Error 8/28/2017 6:59:18 AM Failed to queue test run '': No
such host is known.
I have Visual Studio 2017 on my client. The 2017 Test Controller is installed and configured on a second machine running Windows Server 2016. The 2017 Test Agent is installed and configured on a third machine running Windows Server 2016. The Test DB is on SQL Express on the second machine, same box as the Test Controller.
The configuration of all items worked fine (Test Controller, Test Agent, etc) without any issues or errors.
I installed VS 2017 on the Test Controller machine and was able to run tests without issue.
I can debug from my client without issue, but when I try RUNNING the test, it states the error above.
I can "manage test controllers" and see my controller, as well as the test agent listed, all in "ready status." Additionally, setting the LoadTest DB has a "test connection successful" message when setting it up.
My current .testsettings file is set up with the role to have all agents associated with my test controller be for running tests. It is set as the active test setting.
I've put the FQDN in all the setup, and added all the associated machines to the host files on each box.
The firewall has been disabled on every box to try that to no avail. Network Sharing is on, Printer sharing is on, ports are open. Verified this with port scanners, checking settings on the servers, and I can ping and NSLookUp each box from each other.
I've tried recording brand new tests and running existing tests (ones that worked if I ran VS2017 on the Test Controller) to no avail.
At this point, I'm really not sure what else to do or try, nor what other information to provide. I'm dumbfounded as I've read all the troubleshooting docs on network permissions, local permissions, etc. The only thing I haven't done is made an AD group for the machines involved and adding those to local admin groups.
If anyone could help, PLEASE, feel free to ask questions and I'll do my best to provide the info.
You can confirm these:
Create a load test in VS17.
On one computer, you configure a test controller in a domain.
On another computer, you configure a test agent in a different domain.
Note: The two domains trust one another.
You run the load test on the test controller computer and the test agent computer.
Edit:
Connect your controller computer and get its hostname.
Go to host file "C:\Windows\System32\drivers\etc".
And add hostname as IP address.
At last VS17 will successfully connected to your controller.
I had the same issue. The problem is that there was no route BACK to the client. I needed to add a fully qualified entry for the cient to the hosts file on the controller. This was compunded by using a VPN to Azure.
To clarify you need the FQDN of your client added to the hosts file of your controller.
I have a .NET 4 webservice running on IIS Express 7.5 on a 2008 Server
the service runs fine for a couple of hours or even a day but after some time the process crashes with an error message failed to translate IP address + Hostname to Site Id which is displayed red in the console output.
I streamlined the applicationhost.config to only contain a single site and the binding is only to an ip address and localhost but no success.
I use this command line to start IISExpress
iisexpress.exe /config:c:\myconfig\applicationhost.config /site:mysite
First of all a solution for the error would be great but any information on how to optain more data for this error would also help. I already checked the eventlog but can't find anything.
Well, I upgraded to IISExpress 8 which runs stable now.
I did not know what caused this issue, but I belive it was somehow related to heavy load on the server since to often (but not exclusively) happend during a scheduled backup.
I'm getting following errors on the test controller machine, when I'm trying to run CodedUI Tests remotely:
(QTController.exe, PID 3032, Thread 12)
ControllerDeployment.DoDeployment: System.Net.Sockets.SocketException
(0x80004005): No such host is known
During controller and agent configuration no errors came up. And when I go to Manage test controller dialog in Visual Studio I can see all the agents active. But when I try to execute any CodedUI test remotely it's hanging forever.
Not sure if it's connected with the fact that I've upgraded client/controller/agents to 2012 versions recently, but I've started seeing the problem only after this upgrade.
From Microsoft KB 2643086:
This issue occurs because the test agent computer sends its Network
Basic Input/Output System (NetBIOS) name instead of sending its Fully
Qualified Domain Name (FQDN) name to the test controller computer.
When the DNS server of the test controller computer does not have the
IP address mapping of the NetBIOS name of the test agent computer, the
issue that is described in the "Symptoms" section occurs.
You should ensure you are using fully qualified domain names (FQDN).
There is also a hotfix is available from Microsoft. However, you have to contact Microsoft Customer Support Services to obtain the hotfix.
I had similar problem, still not completely resolved but a workaround is to install Visual Studio on controller box and keeping result DB on same box.
Mostly the issue is restriction / firewall on VPN which might be blocking incoming traffic on TCP ports of machine / laptop.
