Some details of your network and the error are appropriate.
ISA determines "spoof" by comparing the source IP of teh received packet to the 
Windows routing table and the address assignments of the network where the 
packet was received.
If the combined data doesn't agree, ISA calls "spoof".

Hello,
I keep getting this error message under the alerts in the monitoring tab
on ISA 2004 server.

The message is.

ISA server detected a spoof attack from internet protocol listing the ip
address xxx.xxx.xxx.xxx which is my internal sbs2000 server. I have ISA
2004 running on a seporate box.

Thanks Jim
