We have replaced our DHCP server with a Windows 2008 DC.  We installed DHCP and put in the router, DNS, and domain name.  When we do a /release then /renew, the DNS numbers are correct.  Less than 2 hours later, the DNS addresses have changed to our old DNS servers (both primary and seconday change).  Everything else is still correct.  It shows the correct DHCP server, it has the correct IP address, just the DNS numbers are from our old servers.  Any help would be greatly appreciated.  Thanks.
