The session setup to the Windows Domain Controller %1 from computer
%2 using account %4 failed.  %2 is declared to be a BDC in domain %3.
However, %2 tried to connect as either a DC in a trusted domain,
a member workstation in domain %3, or as a server in domain %3.
Use the Active Directory Users and Computers tool or Server Manager to remove the BDC account for %2.
