Hello
I have a problem with DNS in windows 2008R2. there is a policy prevent DNS resolving name to IP and I can ping any computer by IP put I cannot ping it by name although when I use "nslookup" on cmd the computer can see DNS server. Another problem I can join Computer to domain put when I want to add a domain user to local admin group the computer cannot see the domain and user show as s-1-5-21 if I could add user.I don't know the policy and how to delete it.
