I am currently trying to set up a secondary DC on a Windows 2003 Domain and am getting the following error,
"The Active Directory 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. . . ."
I was under the impression that this was needed only when upgrading from a windows 2000 domain . . this is not what i am doing. The domain i am adding the secondary DC to is set up with only one DC at the moment, that DC is also running on Server 2003. Searching experts exchange i have been able to find people who have had to run ADPREP whenadding a secondary DC to a domain where the primary DC is running SBS2003 - but not anything where the primary and secondary are running 2003 Standard.
Running DXDIAG on both machines the only difference i can find is that the new server (which i am trying to set up as the secondary DC) differs slightly in its listing - as shown below.
Primary Domain Controller - Windows (5.2, Build 3790) Service Pack 1 (3790.srv03_sp1_rtm.050324-1447)
Secondary (Machine i am trying to add) - Windows Server 2003, Standard Edition (5.2, Build 3790) Service Pack 1 (3790.srv03_sp1_qfe.050504-1733)
The only difference on the main DXDIAG screen is that the primary is showing Service pack 1 and the secondary is showing Server 2003 R2 - could this be the reason i am having this error.
Anyway long story short - so i definately in this environment still have to run the ADPREP /FORESTPREP commands on both machines and if so should i use the disc from the R2 install?
Thanks for ploughing through this.
