You'll need to update SBS 2003 R2 with the Server 2003 R2 AD Schema. This is because even though SBS 2003 has the "R2", it doesn't actually include Win2k3 R2

Good luck!
Main Topics
Browse All TopicsI am trying to promote a Windows Server 2003 R2 to an additional domain controler in an Small Business Server 2003 Std (pre SBS R2 release).
I get the following error
"The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer."
I tried to run the Adprep/ Forestprep and Adprep /domain prep on the SBS 2003 server; both report that Domain information has been updates.
Is tghe a problem with adding the R2 release?

"Using the Administrator ID" doesn't mean anything. Have you verified that this account is actually a member of the two groups?
Again: was the inital installation of this SBS a Windows 2000 that has been upgraded, or how did the "C:\WinNT" system folder come about?
Anything in the event log?
Run netdiag.exe and dcdiag.exe on the DC, check for errors.

If you haven't done so yet, the next thing I'd try is to simply reboot the machine and try it again.
You might have a look at this article before you try it again; shouldn't be necessary on W2k3, but the WinNT is somewhat strange, unless this was an unattended setup in which someone deliberately used WinNT as systemroot.
