We have a site running SBS2003 and have recently purchased windows server
2003 r2 std to install at a remote location for a small number of users,
The sites are connected by vpn tunnel and can see each other no problems
(the 2k3 server can join the sbs2003 domain no problem).
Trying to run dcpromo as an additional DC brings up the following error:
“The operation failed because:
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. For more
information about using the Adprep, see Active Directory Help.
The version of the Active Directory schema of the source forest is not
compatible with the version of Active Directory on this computer.”
Now i may be wrong but isn’t the adprep tool used for win2k servers?
I tried running the adprep tool anyway and get the message “forest-wide
information has already been updated”.
Would really appreciate any help!!!
