Vista - DHCP console shows wrong server name

Hi,

I had to rename a DHCP server running Windows 2003 in an Active Directory
environment. I also change the IP of the server. Now when I open the DHCP
console and I want to add that dhcp server from the authorized DHCP server
list, that server still shows with the "Old" name. When I click on it to add
it, it tries to connect to the server with the "old" name and the "old" IP
address. How can I make the changes that I made reflect in the DHCP console?

Thanks,
