PDF Files Do Not Index after Adobe Filter Is Installed

• Microsoft Index Server version 2.0

SYMPTOMS

After you install the .pdf (portable document format) filter from Adobe, you may notice that .pdf files stop indexing after you restart Index Server or restart the computer.

CAUSE

When Index Server starts, it re-registers all the filter DLLs One of these DLLs has a default association with the .pdf extension and therefore registers itself as the filter for these files.

RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To resolve this problem, follow these steps:

1. Start Registry Editor (Regedt32.exe).



2. Locate the following key in the registry:
   

   
         HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ContentIndex
    




3. Add the path to the Pdffilt.dll to the DLLsToRegister key. The path to the .pdf filter should be added as the last entry in this key.



4. Quit Registry Editor.

MORE INFORMATION

When Index Server starts, Query.dll is re-registered (it is first in the list). However, Query.dll recognizes the .pdf files and associates them with the null filter. When you add Pdffilt.dll to the end of the registry key, it is allowed to re-register the .pdf files with itself.
