SYMPTOMS

After you upgrade to Windows 2000, the Indexing Service may no longer index .pdf files or other files associated with a third-party filter.

CAUSE

The Query.dll filter shipped with the Windows 2000 Indexing Service registers itself differently than the old version(s) used with Index Server 2.0 or Site Server 3.0 Search. The new registration method can override associations in the registry for filters using the old registration method.

WORKAROUND

To work around this issue, do the following:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

  1. Stop the Indexing Service
  2. Start Registry Editor (Regedt32.exe).
  3. Locate the following key in the registry:

    hkey_local_machine\system\currentcontrolset\control\contentindex

  4. Open DllsToRegister and remove the entry pointing to Query.dll.
  5. Open hkey_classes_root\.pdf and remove the PersistentHandler registry key.
  6. Repeat the process for all other extensions.
  7. Restart the Indexing Service.
  8. Under your catalog, find the Directories folder and right-click the directory containing your data.
  9. Select All Tasks, and then rescan (full) to force the re-indexing of the documents.

This keeps the filter from rewriting its registry associations when the Indexing Service starts.
