I am replacing my domain controller with a new server. The old server is win 2k and I am replacing it with Win 2003. I have a number of other servers on the network most of which are win 2k.
However, about 6 months ago I added a new exchange server running win 2003. When adding I ran adprep etc to extend the schema. Do I have to do this again when adding the new domain controller or as I ran it before I can assume the scema is okay and extended to allow win 2003 servers to be added. I made the new exchange server a backup domain controller.

It sounds like you already have a 2003 Domain Controller. So as long as the new server is 2003 and not 2003 R2 you should not have have to run ADPrpe again. If it is R2 then you will need to update the schema again to the R2 version.

As KenMcF said. This is only one time action. If you did adprep for 2003 and now you'd like to use R2 or Windows 2008 you have to do it again, if not, just run dcpromo on new server to make it as DC. Set also there GlobalCatalog and DNS service for redundancy.

the new server is R2 so i will have to run it again.
Just a thought can i run adprep during the working day whilst users are logged onto the system?
You can run it during the day, but my preferance is to do anything like this off-hours.

Yup, it doesn't require any downtime. But remember this is one way action, you cannot revert it back :)
