Yes we are using Win2k3 as our DNS servers. There are 3 DNS servers, one for each location hosted on each DC.
I say it is not configured correctly due to various situations. For one thing the server was hurried out, mysterious software is installed (which looks like spyware or something, lacking updates, not running as smooth as DC1 and DC2. No issues with those DCs.
Essenstials is not up and running. And due to a contact with the out sourcing company, I cannot monitor the servers with Essentials (yet).
So far the only errors are the Netbt errors, no others at this point.
