We have a Windows SharePoint Services 3.0 farm that consists of 4 servers:

  • Admin Server
  • Search Server
  • Web Front End 1 (Load-Balanced)
  • Web Front End 2 (Load-Balanced)

A user has reported that Office 2007 documents are not being indexed. In troubleshooting the problem, I found these articles:

https://www.microsoft.com/en-us/download/details.aspx?id=20109 https://support.microsoft.com/en-us/kb/946338/en-us?p=1&wa=wsignin1.0

When I look on our Admin Server and our Search Server, the Filter Packs have already been successfully installed, and the entries in the registry are correct. When I look on the 2 web front end servers, they do NOT have the filter backs installed.

I'm attempting to take over some of the administrative responsibilities from people who have left the company. I'm not sure if this is a new issue or if it has always been this way.

My question is - do the search filter packs need to be installed on the web front end servers? Or is installing them on the admin and search servers adequate? If the latter, what else could be causing this problem?

Thanks in advance,


  • did you check the Crawl logs, if their is any error? What is your crawl schedule, If you did not run a FUll crawl in last couple of month then run that and test it.

  • Thank you, Wagas, for your response. We run a full crawl once per month and an incremental crawl daily. There are some errors in our crawl log, but none are present for the site in question. Jun 24, 2015 at 16:10
  • what file types they are not getting?

  • The issue was reported on an xslx file. There is an entry for this type in the registry of both the admin and search servers. Jun 24, 2015 at 16:19
  • can you search that file in crawl log( i am not sure if you can in wss 3.0, long time ago)

Couple of things to check.

  • Run a Full crawl if not done before.

  • Make sure the Search is crawling that document.You should check in the Crawl history /log if the specified file indexed.

  • Check the crawl logs for potential error.

  • Also try to upload the different 2007 files and run the full crawl and test it.

from communications, looks like your problem with a specific file. I would make a copy or delete and re-add it and then run full crawl and test it.

Note: On the side note, Filter Pack is prerequisite for SharePoint 2010, that's mean it should be install on all server in the farm. But no sure about wss3.0, because my experince is telling this is required only on search servers.
