PRB: The Specific Request Cannot Be Executed From Current Application Pool

SYMPTOMS

While executing a request you get HTTP status 403.8 with the following message:
The Specific Request Cannot Be Executed from Current application pool

CAUSE

The eSpace that is processing the request is location one application pool, and the customer error handlers for that eSpace are on another application pool.

By default IIS checks that the eSpace is redirecting the request to another application in the same application pool.

SOLUTION

To instruct IIS not to check this, simply copy the contents below to notepad and save the file as "FixAppPool.reg" on the server.

------------- START COPYING BELOW THIS LINE -------------
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters]
"IgnoreAppPoolForCustomErrors"=dword:00000001
------------- STOP COPYING ABOVE THIS LINE -------------

Import the file into the server's registry by double-clicking the file or using RegEdit.exe.
