I am trying to promote a member server that was configured with WindowsServer 2003 R2 SP 1 into an existing Domain/forest. The existing domain has 1 Windows Server 2003 SP1 domain controller and 1 2003 Exchange Server (also running W2K3 R2 Sp1). When I try to run the Active Directory wizard (adprep) I get the following error: "This version of the Active Directory Schema of the source forest is not compatible with the version of Active Directory on this (member server in question) computer.
This is the same error you get trying to promote a W2k3 member server to a Domain Controller in a Windows 2000 domain.
Has anyone else seen this? Is there a quick fix? Do I have to upgrade (spelled "r e i n s t a ll") the w2k3 DC to W2k3 R2?
P.S. My domain functional level is still set to Mixed as I do have 2 other Windows 2000 servers in this Domain.
Thanks for your input........
