I have a technician that is having this situation in a few sites. He logs a domain user to his/her machine and the users can't resolve names. Try to use Outlook 2003 and can't find the server. If he setup the domain user as a local admin then he can resolve names and everything works fine. Where should I look to troubleshoot this problem. I always thought that DNS registration didn't have anything to do with the user on the computer. Thanks!
