I either have to wait 3-5 minutes for the system to comes back up or go to the Microsoft Firewall services and Stop / Start it. Is there any reason for it. This has happened before but it correct itself. Now it is happening more often. I have all the updates for 2003 server and ISA installed. thanks _________________________________________________________________ Helping your favorite cause is as easy as instant messaging.
