We�re running a Small Business Server 2000 behind a Watchguard firewall. The latest servicepacks are installed. Sounds familiar to anyone? I have searched through technet several times without finding anything relevant. /Andy ______________________________________________________________________ This messsage was sent using the trial version of the 1st Class Mail Server software.
