If you're not using multiple internal networks, and all computers are on the same subnet, it is most likely NOT a result of your ISA settings. I have that problem here occasionally, but it is usually a result of spyware. -----Original Message----- From: Scheele, Brian [mailto:bscheele@xxxxxxxxxxxxxxx] Sent: Wednesday, April 13, 2005 08:31 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Windows 2003 Service Pack 1 http://www.ISAserver.org I am not sure if my problem is related to the upgrade, but I just replaced ISA Server 2000 with ISA Server 2004 SP1, which is running on Windows 2003 SP1. My users are missing their home drive when they log in in the morning. ISA Server is on its own box. Probably a totally different issue to fix.
