How to confirm DNS is setup correctly?
Posted on 2014-12-22
All of the sudden, our internet connection has become very slow and I think it has to do with our DNS configuration. We have one domain 2008 R2 and very site is a DC controller used for file and print sharing. In addition, we also have DHCP and DNS on each site. How do I confirm that our DNS is setup correctly. If I do a dns lookup, I am getting the following:
DNS request timed out.
time out was 2 seconds.
Is there a tool or command that I can run to assure all my DNS settings are right?
