Operating System - Windows 2008 R2 Service Pack - Service Pack 1 IP Address - 10.50.1.111 Subnet Mask - 255.255.255.0 Gateway - 10.50.1.1 DNS Server - 10.50.1.90
Other servers are using 10.50.1.90 as their DNS server and are not having any problems. This tells me that the problem is not with the DNS server.
I can ping 10.50.1.90.
The firewall is disabled.
If I run nslookup and query the name of 10.50.1.90 (OfficeDC1.office.org) it says, "*** [10.50.1.90] can't find OfficeDC1".
If I run nslookup and change the server to 8.8.8.8 and query google.com it says, "*** [8.8.8.8] can't find google.com: No response from server".
Any thoughts?
Have you tried restarting? Or specifically restarting the service?
and restart DNS Client service?
In this case, the problem had nothing to do with DNS. The problem was the TCP stack was corrupted. I uninstalled and reinstalled the network adapters and ran the command below.
After the command ran I restarted the server and the DNS problems were resolved.
