I have an old 2000 Server acting as the DC. I have two additional servers 2000 and 2003 also running active directory. I have introduced a 2008 server which will be replacing both the 2000 servers. I have done all the adprep work, ran dcpromo created the DNS role as directed when running the dcpromo, (did not add a forwarding zone because not quite clear what that does) and did all the role transfers. The 2000 server has DNS running and the 2008 has DNS running.
All the workstations have static ip's and they where first pointing to the old server now they are directed to the new server. I have no login issues or login script issues and everyone can access data on the new server without issues.
Once I finished making the changes to the static DNS on the workstations, I turned off the DNS service on the old server and have been running fine for the last week. Today I introduced a new computer I assigned it a static IP with the DNS pointing to the new server and when I tried to join the domain, I keep getting messages that the DNS cannot resolve the domain name. I can ping both the ip address and the server name without problems. When I started the old DNS service and changed the DNS ip to reflect the old DC server it popped in just fine.
I am confused. Any suggestions.
