Hello, Only over the past month or so, I have been receiving almost weekly notices from my ISA server that states: "ISA Server detected a change in the IP routing table of the computer." Then always about 2-3 minutes later, it says it again. My guess is it is changing, and then changing back a few mins later? Where can I find out more information on this? route print? Is that what it is referring to? Any ideas why this would only happen infrequently? Environment: ISA 2000 SP1 in Integrated Mode on Windows Server 2003 no other apps or services, in a Windows 2000 AD Domain. Static IP from ISP. Thanks! Paul
