Problem

The Web Viewer is does not respond to new requests. When you remote desktop to the server an unhandled exception from w3wp.exe is shown. The dialogue is stopping the Web Viewer from continuing.

Solution

To disable Just-In-Time debugging delete the follow registry keys in the RegEditor:

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

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\DbgManagedDebugger

If your computer is running a 64-bit operating system, delete the following registry keys also:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\WindowsNT\CurrentVersion\AeDebug\Debugger

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