We have only 1 DC running
1)
WINDOWS Server 2003 R2 Small Business Server.(standard ed)32bit
the AD is running off this server,
Recently purchased another server running
2) Windows Server 2003 Standard x64 Ed.
I wanted to make the second (2) server (Windows Server 2003 Standard x64 Ed) my backup domain controller.
i tried to run DCPROMO after running adprep successfully on the DC. But when i ran DCPROMO, i got error to prepare both forest and domain (which has already been done)
& The version of AD schema of sourse forest is not compatible with this version of AD.”
Dell mentioned that even though they are both running windows, i cannot promote the 2nd server as AD version is not the same. If i want to create another backup DC i have to install 2003 SBS on it.
wondering if this is correct and if anybody has come across this issue.
