I think we are having a problem with our DNS within my DC. I am having problems with users logging in. It says the domain cannot be logged into. Also when I try and ping a pc or anything on our network it returns the name along with our domain name. Someone told me you can uninstall DNS on the controller and reinstall DNS and it will rebuild and not affect Active Directory. Is this true? I really don't want to try this and lose my Active Directory. Any help or direction would be greatly appreciated.
