We have a login script that maps drives based on groups. We have been using this script on windows 2003 with no problems. The scripts actually will run on a 2008 server as this is a terminal server. If I put a user directly in the group that we have in the login script it works fine, however if there is a group within the group that we call in the login script it does not work. Again it works fine on 2003 but will not work on 2008.
