NO NO NO! I Don't have a gazillion Domain Admins!! I was joking that it COULD be a possible solution. My scripts may not be the best, but I'm not stupid.

The reason for the @PRIMARYGROUP as the delimiter was to map the group drives of only the department the user is in and not any other %groupname%_PRIV that the user may belong to. If a user needed another department's Drive, they could map the %groupname%_PUB themselves. Thereby giving everyone a "share drive" that is not one big Dump of forgotten information.
