I have a Single Domain AD server (windows 2000), and about two weeks ago I started adding a VOIP phone system on the network. For the phones on the system to work they need the Phone Server to be the primary DNS server. So I simply went to my DHCP server and changed the DNS Servers to serve out. Before I had my local DNS server, which is my PDC and an external DNS server listed. Now I just added the Phone System Server to the DNS list, and put it on top. Now since I have done this I have been having issues with domain users losing authetication to the domain. When they try to access the network it will ask for a user name and password. I am not sure if this is a DNS issue, but I am interested in what you have to say. At first I thought maybe my AD was going corrupt.
Thanks for the help....any help would be great!
