Thanks for responding.<br />
<br />
This server is a test server. Therefore, would it be easier to recreate the DC?<br />
<br />
Also, I don't know what you mean by:<br />
<br />

<blockquote>
domain functional level is not high enough to use the netdom command
</blockquote>
</div>


<div>
Open active directory users and computers, right click on the domain and deal with forest/domain functional level<br />
Raising them to as a high level as you can noting your setup.<br />
I.e. If you have a 2000 server, you can not go higher........
</div>


<div>
Basically for the netdom to be able to be used to rename a DC you need to have your domain functional level at 2003 or higher. <br />
so when your domain was setup the functional level was not 2003 or higher. As Arnold provided above you can increase the level using the AD tools. if you still have a 2000 or NT domain controller on your test environment you will need to update it or remove it as a DC prior to increasing the functional level otherwise you should be fine increasing it. <br />
If you don't want to deal with that and just rename the DC just rename it the same as you would a regular machine and wait for DNS and AD replication cycle prior to performing any test or authentication against the server your renaming.
