I have a server named Cognos. It used to be assigned IP address 192.168.0.69. for various reasons, I gave it a new IP address of 192.168.0.7. When I try nslookup and type in Cognos, it resolves to the old IP address of 192.168.0.69. I have done ipconfig/flushdns on both of my DNS servers, stopped/started the DNS service, rebooted both of the DNS servers with no success.
I have also deleted the old name out of the WINS database on the WINS server. I have performed an ipconfig /register DNS on the Cognos server. It seems that no matter what I do, it still shows up as COGNOS. Either thru nslookup or when I ping. It fails the ping because it is resolving to 192.168.0.69 when it should be resolving to 192.168.0.7. I can ping 192.168.0.7 and it comes back fine.
