Consider the following scenarios.

Scenario 1

You install the 2007 Microsoft Office servers Service Pack 1 (SP1) on a server that has the Foxit PDF IFilter installed. When a Microsoft Office SharePoint Server 2007 site collection on the server is searched by the SharePoint Server 2007 for Search service, .pdf document types are not indexed. When you try to search for .pdf documents in the SharePoint Server 2007 site collection, the .pdf documents are not found.

Scenario 2

You install Microsoft Windows SharePoint Services 3.0 SP1 on a server that has the Foxit PDF IFilter installed. When a Microsoft Windows SharePoint Services 3.0 site collection on the server is searched by the Windows SharePoint Services Search service, .pdf document types are not indexed. When you try to search for .pdf documents in the Windows SharePoint Services 3.0 site collection, the .pdf documents are not found.

This problem occurs because the Adobe PDF IFilter GUID is hard-coded in the 2007 Microsoft Office servers Service Pack 1 (SP1) and in Windows SharePoint Services 3.0 SP1. During the installation of the 2007 Microsoft Office servers Service Pack 1 (SP1) or Windows SharePoint Services 3.0 SP1, the Foxit PDF IFilter GUID is replaced by the Adobe PDF IFilter GUID in the registry.

To work around this problem, use one of the following methods.

Method 1: Reinstall the Foxit PDF IFilter
