I'm having issues getting a 2008 Policy to apply on my 2003 domain. I attached Group Policy Management from a 2008 server to the domain and setup it's own policy. The policy is User Configuration > Preferences > Control Panel Settings > Folder Options > Open With.
I check gpresult on the computer and it shows that it is applied, but under Filter it says Filtering: Not Applied (Unknown Reason). I don't see anything in the event log. Under the group policy scope, I have security filtering set to apply this to all Authenticated Users.
How do I start to troubleshoot this?
