Three possibilities:
1. you are supporting VPN clients. Each time a client connects or disconnects,
the Windows routing table changes
2. you have a site-to-site VPN; if / when it is dropped / reconnected, the
Windows routing table changes
3. your server is reacting to upstream router MTU change requests; when the
Windows stack has to retransmit with a changed MTU, it
"updates" the routing table.

Subject: [isalist] Routing Table Change
http://www.ISAserver.org
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
