Adding Windows 2003 SP1 to existing Active Directory Domain – urgent

I have a domain consisting of 1 PDC, and 1 BDC. Those 2 were 2000 servers. I am introducing a 2003 server to host Exchange, and cannot add it to the existing doman w/Active Directory. I ran the adprep tool, and it was successful. The error I get on the 2003 Server is "The operation failed because: The Active Directory Installation Wizard was unable to convert the computer account XXX to a domain controller account. "Access is Denied." Type the username and password of an account with sufficient priveliges to create an additional domain controller for the JenkinsConstruction.com domain." Now, I am the NA, so I have sufficient priveliges, but it does not work. I even used the Administrator account, and that does not work either. So, I decided to upgrade (earlier than planned) my PDC to 2003 server thinking that would eliminate the problem. The upgrade went fine, but I'm still getting the same error. Actually, I have a NAS that has 2003 Appliance Server on it, and it has the same problem. You may email me directly at ashy@jenkinsconstruction.com. Please help!!! TIA!!!

Hello,

I’m curious as to why your running ADPrep on a member server? ADprep is a utility which prepares or sets the ground work for new W2K3 AD domains or forests. This utility is run from a DC and is run only once from either the infrastructure master (domain) or schema master (forest). All other servers, member servers or additional DC’s can simply be added through systems properties => computer name tab and click network ID to start the wizard. In your case your server thinks it needs to be a DC which is why your getting the error.

Try removing it completely from the domain, wait 15 minutes for replication or force replication (as a precaution, shouldn’t really have to) and re-add it as a member server without running ADprep.

Good luck!

    Why do you want the exchange server to be a domain controller? Microsoft discourages using exchange on a domain controller. Are you running in native 2000 mode? Also PDC and BDC don't have the same meanings they had for NT. You have several single purpose master roles, see: http://support.microsoft.com/kb/q197132/ Our exchange upgrade from 5.5 to 2003 went with minimal problems but we didn't try to make it a domain controller. rt

    You can remove the domain controller role to return it to a member server without rebuilding the machine, since you ran adprep to begin with. Kevin
