Help! Last night we had to re-IP one of our Windows 2003 Domimain Controllers that is running DHCP. After changing the DNS entry for the DC and changing the IP address on the DC we were able to go to our ROOT DC and add the Server with its new IP address to the list of authorized DHCP server but when we selected the entry for the DC with the old IP address and pressed "unauthorize", a message appeared on the screen saying that there was no object on the server. So what we have now is two entries in the DHCP authorized server list for the same server name but with different addresses and I can't remove the old one through the MMC or with NETSH. We would REALLY like to get rid of the entry with the old IP address. Can anyone tell me how I might get rid of this bogus entry? Thanks.
