I have a Folder Redirection policy and I changed the path on our 2003 domain. However even after gpupdate /force the client (Win 7) still tries to access the old path and give me the "Windows cannot access ..." and the old share. Nothing has changed and the group policy is being applied , it simply isn't updating?
Try using
gpresult /v
. That'll give you a great starting place to start looking into if the policy is being applied correctly or not.
