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
