I’m adding a Windows 2008 RC2 (x64… if it matters) to an existing 2003 domain.  Join the domain, everything’s happy, run all my forestprep & domainprep goodness… but dcpromo kept shitting itself with:

“Failed to examine the active directory forest.  The error was: The operation cannot continue because the LDAP connect/bind operation failed: error: 58”

The only thing I could find was this page which suggested the local admin account password had to be the same as the forest root domain password.  Before I went through all the account renaming and hunting down the password (all your admin accounts get renamed, right?  And no one really has that password?) I decided to just disable the local admin account on the 2008 server first.  It worked.  “WTF?O” indeed.
