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 email@example.com. Please help!!! TIA!!!
