I've run into a small problem which I'd like to be absolutely certain about and I hope that you can aid me in this.
We have an existing 2003 domain - schema version 30 - where I've identified a single point of failure regarding one of our domains. We'd like to get another DC up and running but we only have 2003 R2 available from our VLSC.
When I try to do a dcpromo on a new 2003 R2 server I'm being informed that it's not possible since the schema version isn't compatible and that I need to do an AD- and forest preparation. On the other hand, I've been informed that it's absolutely possible to add a 2003R2 server as domain controller to a 2003 domain without doing the preparation.
If this is true, how is this done? Initial Google'ing haven't yielded any results so far.
There's no problems in doing an forest preparation but we're in an ongoing project of upgrading to a 2008 R2 platform so AD and forest preparations are already scheduled. All I'd like is to eliminate this SPOF in the meantime.
Thank you for your time.
