How to stop "Just In Time Debugging" messages blocking a buildserver

Our buildserver (TeamCity, much recommended), runs our a whole bunch of testsuites on our finished c++ program.

Once in a whole, a test causes our program to crash, often bringing up a VisualStudio dialog offering me to JustInTime debug the crash. The dialog stops the buildserver from progressing. Instead of the build marked as failed, it just hangs. I've turned off the Just In Time debugging feature in VisualStudio, but when it's turned off, you still get a message "Couldn't JustinTime Debug this, you can turn it on in the options".

Does anybody know of a way to ensure that any unhandled exception in a program does not result in any modal dialog?

This MSDN article explains how to disable Just-In-Time debugging on a Windows server. I've included the relevant portion of the article below:

After Visual Studio is installed on a server, the default behavior when an unhandled exception occurs is to show an Exception dialog that requires user intervention to either start Just-In-Time debugging or ignore the exception. This may be undesirable for unattended operation. To configure the server to no longer show a dialog when an unhandled exception occurs (the default behavior prior to installing Visual Studio), use the registry editor to delete the following registry keys:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\DbgManagedDebugger

On a 64-bit operating system also delete the following registry keys:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger

  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\DbgManagedDebugger
