we followed the article at http://support.microsoft.com/kb/927675/en-us to implement the pdf filter for wss 3.0. But the registry entry mentioned on step 2 (adding a new entry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Search\Applications\GUID\Gather\Search\Extensions\ExtensionList) is lost if we reboot the system.
Does anyone have any idea why that might be happening? We installed the adobe reader 10 and tried to configure the pdf filter for wss 3.0
Ok, found the problem. After changing the registry you have to stop and restart the share point search service. No idea how they are related tho!
Following are the commands: net stop spsearch net start spsearch
