This morning upon looking at the server, DNS duplicate entries are everywhere.  So many computers now have the same IP entry in DNS, why would this happen so suddenly?  And why to so many machines at once?

Have you changed added a DHCP server or changed the service over to another server? Have you added or moved anything in your network?  I would clear the cache, update data files, and scavenage old records in DNS.

Hi,
most likely something wrong happened with a DHCP server within the domain. I hardly imagine something different. No hints from the Event Log?
Cheers

Sounds like a virus or worm.   Check to see if you have some sort of malware bouncing around in your network.

Looks to have solved it, the scavenging took away a little to much, but it seems to be fine after I added some missing a hosts.
