Folder Redirection still points to old server for Windows 7.
A quick work around is to create a hosts file on the workstation with the old server name but the IP Address points to the new server.
Be sure to make a backup of the users folder before making any changes.
DON'T MAKE an A record (or a host record) on the DNS server for the old server, or you will end up with a disaster. Just the hosts file on the workstation.
Hope it helps.. :)
