Do you mean the servers went really slow for access to the web or access to the console was really slow or both. Nachi behind your ISA box will make CPU go to 100%, everything is still working but if you go the console the server looks like it is locked, but it's not, pull the cable from the NIC to the internal network and CPU usage will drop the 0% almost immediately, we had to do this to isolate which building had a Nachi infected machine in it. So more likely is that new network has some infected PC's on it.

Basically what would happen is that the ISA servers in the array would crawl for access (we just do outbound for web access). We would reboot them, and they would come back up fine. Couple of hours would pass, and boom, it would happen again. Of course it did not help we moved to a Win2k+3 DC this weekend so we were trying to track that down. Anyway, we found someone decided to bring up another segment. so these new IPs ranges were hitting the ISA servers. Since this was not a known IP their were no routes or LAT entries so everything was routed out the external adapter, not the internal. Added them and bam, everything cleared up. The back of my mind says this was a fluke and the problem is going to creep up again. Anyone have any ideas for a general slowness problem.. btw, my car is making the pinging noise.. I know, ghost error, but this is stumping me. Anyone have any issues with win2k+3 DCs?
