I am always getting the "A Duplicate name has been found on your network......" error on one of my servers that is also a DC. If I run an nbtstat -n on it to find out what's going on, I get (3) listings for the server name (1F, 00, 20), and (3) listings for the domain name (00, 1C, 1E). Isn't that the correct listing? How can I *really* find out who is causing the duplicate name error? Thanks.
