When I try to promote a windows 2000 server to a domain controller by running dcpromo. I alway get the same error, "Operation failed because: Failed to modify the necessary properities for the machine account bcat-backup1$" Access is Denied. I am using the an enterprise admin account to promote the server. I have also tired to remove the server from the domain and add it back in. I have even tired another windows 2000 server and got the same error. Any help would be appreciated.
