We are running into a problem where client computers are an incorrect DHCP sever in thier IP configuration.
Posted on 2009-02-20
Our network has a DHCP server at address 10.0.2.1. clients that have not rebooted in the last 24 hours are showing the proper DHCP and DNS servers in their IP config. But, on a system that was rebooted, it is showing up with a DHCP server of 10.0.2.252 (our WAN network Router). Quest is assuring us that there are no DHCP settings on their router
They are also getting DNS server information for address's outside our netwrok
126.96.36.199 and 188.8.131.52
A ping or HTTP connection shows the device as our Qwest Adtran router as expected.
Our internet router is showing some log entries
Deny IP spoof From (10.0.2.255) to 184.108.40.206 on iterface inside
How can i determine where the client computers are getting the incorrect DHCP server?
