Network currenly consists of One Windows 2000 Server that is the Root Domain Controller. This is old and starting to fail. Another Windows 2000 Server that is another Domain Controller. One Windows 2003 MEMBER server with SQL 2000 on it. I have a NEW Windows 2003 R2 SP2 server that I need to install active directory and make the root DC. I ran adprep /forestprep on the root DC. There were no errors listed. I let it sit overnight. I ran adprer /domainprep on the Root DC then let it sit for about a 1/2 hour. I then tried to install active Directory on the NEW server. I get the following message:
"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 propare both the Forest and the domain. For more information about using adprep - see Active Directory help.
"The Version of the Active Directory Schema of the Sorce forest is not compatible with the version of Active Directory on this computer".
I have shut down the network and restarted. Since the ROOT DC was having problems, I moved the FISMO roles to the second Windows 2000 DC, Turned off the original root DC. I am able to access the network from all workstations with out a problem. I then re-tried the Active Directory installation. I get the same error.
Does any one have any ideas????
