I have 1 server running 2000 Server, ADS, Exchange 2000, WINs
I need to add a server for file and print and as a secondary Domain Controller.
I have bought an HP server with 2003 Server.
How can (or can I add) the 2003 server to the 2000 Domain?

You can add the server and run DCPROMO to make it a Domain Controller - this should be fine as long as you don't elevate the domain to 2003 native mode.  (Read this on a message board - not 100% positive of it)

I did run the DC utility on the 2003 server and tried to add it to the 2000 domain and an error came back saying I needed to run a utility on the 2000 domain.
Can't recall the name of the utility.

Run Adprep /forestprep on the 2000 DC that holds the Schema role - you must log into the server with Enterprise Admin permissions.

After that is done, run Adprep /domainprep on the 2000 DC that holds the Infrastructure Master role - you must log in as a member of the Domain Admins.

If those two things complete with no errors you can DCPROMO the 2003 server into the 2000 Domain as you would normally do.

Hope that helps.

Where do I get Adprep?
Are their any concerns regarding Exchange 2000?

Adprep is on the 2003 CD - I think it's in the Support directory.

If Exchange is on a 2000 server then you will be okay.  Do not upgrade the Exchange server OS to 2003 or it will break Exchange.  Exchange 2000 will function fine in a 2003 domain provided it runs on 2000 - you can't install it on 2003, but you sure can upgrade the OS and cause yourself nothing but grief.

One more thing - Exchange 2000 must be minimum SP2 with hotfixes, but SP3 is recommended.
