I am adding a A.D. based domain to my NT 4 based network. I have created a trust between the two both ways and have a DNS server on the AD domain. I have the AD server in the Native mode. The problem i am haveing is that on the AD server in the logon, only the netbios name of the AD domain is available. I do not know why the proper name is listed ( I.E. abc.xyz.com )

Once you have upgraded your NT 4 to W2K AD, you will continue to logon to the NetBios domain name. FQDNs are managed by your DNS server (abc.com).

Just to make sure i am understanding you corectly. Even though the AD domain is complete seprate form my NT 4 domain, i will NEVER use the FQDN to log in to the AD domain. ( IE user@abe.xyz.com )

Regardless of whether you upgrade an NT4 doamin to AD or install an AD domain from scratch, you will always have in effect 2 domain names (the AD domain name - using the DNS name format; and the NetBIOS domain name - using the format you are familiar with from NT).

When installing AD from scratch, when naming your domain, you have a choice of changing the NetBIOS domain name form the default. The default is always the part of the AD domain name prior to the TLD extension.

When upgrading to AD from NT4, youare not given the option of changing the NetBIOS domain name. The NetBIOS domain name will always default to your previous NT4 domain name (regardless of the AD domain name.

The NetBIOS domain name will ALWAYS be the one that shows in the logon box.

Further, when joining an NT client to an AD domain, you MUST type in the NetBIOS domain name for the domain to resolve properly (NT only understands NetBIOS). When joining a Win2K (or later) client to an AD domain, you musttype in the AD domain name to successfully join.
