Index Server Returns HTTP 500 Error

 Last reviewed: May 21, 1997
Article ID: Q160350
The information in this article applies to:
  • Microsoft Index Server version 1.0

SYMPTOMS

Microsoft Index Server processes one query, and then the following error message appears: 

   HTTP/1.0 500 Server Error (The security descriptor structure is
   invalid.)

CAUSE

Setup incorrectly registers the idq ISAPI extension with a partial path. Internet Information Server requires all extensions be registered with a full path. When another service or ISAPI extension changes directory, it may cause Index Server to return error 500.

WORKAROUND

To work around this problem, you need to edit the registry:

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  1. Start Registry Editor (Regedt32.exe).

  2. Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey: 

          System/CurrentControlSet/Services/W3SVC/Parameters/Script Map

  3. Change the value for .ida from "idq.dll" to the following 

          <Systemroot>\system32\idq.dll

    where Systemroot is the system directory for Windows NT (the value of the %Systemroot% environment variable).

  4. Change the value for .idq to be the same as for .ida.

STATUS
