SYMPTOMS

When you try to automatically attach a debugger to the Aspnet_wp.exe process at startup through the Image File Execution Options key in the registry, you may receive the following error in the Application Event Log:
Event Type: Error
Event Source: ASP.NET 1.1.4322.0
Event ID: 1084
Description: The description for Event ID ( 11013 ) in Source ( RouteService ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

After you apply the fix, follow these steps to attach a debugger on the startup of the Aspnet_wp.exe process:
  1. Open
    Regedit.exe
    and locate
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
    .
  2. Add a new key, and name it:
    Aspnet_wp.exe
    .
  3. Add a new string value (REG_SZ) to the newly created key, and then name it:
    Debugger
    .
  4. Set the Debugger value as follows: C:\Debuggers\cdb.exe -server tcp:port=8090 -g
Note There can be no spaces in your debugger update.
