Unable to Execute Server-side Include (.stm) Files

• Microsoft Internet Information Server versions 2.0, 3.0

SYMPTOMS

When you access server-side Include files (.stm), you may receive one of the following error messages:

Requested header was not found

-OR-

Internet Explorer cannot open http://%path%/.stm

CAUSE

This can occur if the IUSR_Computername account does not have proper Windows NTFS permissions set (read/execute) for the Ssinc.dll file. This dll file is responsible for processing server-side Include files (.stm). By default, it is located in the %Winnt%\System32\Inetsrv directory.

NOTE: The location of your Ssinc.dll file may be different than the one specified above.

WORKAROUND

Apply the appropriate permissions (read/execute) to the Ssinc.dll file.
