adding a terminal server to a windows 2003 sbs domain as an additional domain controller

Adding a Terminal Server to a SBS environment requires a few special considerations. I recommend you read Microsoft's white paper on doing so:

Here is a great document. The 3rd link down is that doc:

thanks guys....this is one of the documents i had come across.unfortunatloey it seems to dela more with actually installing t server and then joining that server tot he existing domain as a client  as opposed to joining as an additional domain controller.... ..

In your question you stated; "I currently have a windows 2003 sbs server (pre R2) running.  I needed to add a terminal server the the network."

If this is what you want to do, it's pretty straight forward, but important how you join the domain. On the SBS open the server management console, on the menu to the left select "Server Computers", choose "Set up Server Computers", follow the wizard (server should have a static IP), then from the new terminal server, in a web browsed enter:
http://YourSBSName/connectcomputer  and follow the wizard, pointing to your new server name, when asked. This will automatically configure domain membership, Remote Web Workplace, user permissions, group policy, firewalls, etc.

If you want to add a second domain controller please advise. It is an extremely bad idea to make a domain controller a terminal server as well.

Not this time Robbie_Leggett :-)

just to be absolutely clear.... u guys are saying it is not recommended to use a 2nd server which primary function is to be a terminal server to be an additional domain controller?  that is not really too much of a big deal ... i just thought it would add extra redundancy....

Thanks gerpaqit.
Cheers !
