I've run a small office network using a single Windows Server 2003 (Standard) for several years, it's called Fserver. This server has been performing all network tasks (file, domain controller, DNS, Exchange 2003, SQL etc). It's now creaking a bit.
Have bought a new server to take over several roles from the main server, these include: domain controller, exchange and SQL.
On the new machine, I've installed Server 2003 (64-bit, standard R2) and fully patched it, it's called Gserver. I've started to add roles but have come across a problem when trying to make it an additional domain controller for the existing domain. The idea is that Gserver will act as secondary domain controller for a while, then be upgraded to primary domain controller at a later date.
Running through the 'Active Directory Installation Wizard', it begins the process of configuring the Active Directory. However, it fails with the following error:
'The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep command-line tool to prepare both the forest and the domain'. 'The version of the Active Directory schema of the source forest is not comaptible with the version of Active Directory on this computer'
Now, both machines are Windows server 2003 - so where does this problem come from?
When it says to run adprep.exe - on which machine, old or new?
Any help appreciated
