When a Windows NT 4.0 computer starts up, it normally queries WINS to
locate domain controllers that it can log on to. WINS does not have any
awareness of geographical locations of domain controllers, so, if a distant
or low-bandwidth domain controller is selected, boot and logon times can be
The starting computer queries WINS for the domain[1C] name list. WINS
returns a list of domain controllers, and the computer sends a datagram to
each of them (as well as a subnet broadcast for any domain controllers that
happen to be on the same subnet). The first DC to respond is chosen as the
one to use for logging on.
NetBT has been modified to support multiple domain controller entries in
the LMHOSTS file. Entries can be added to specify preferred domain
controllers to use when logging on. Entries must appear as shown here:
To take advantage of this new feature, LMHOSTS lookups must be enabled. To
enable LMHOSTS lookup, go to Control Panel->Network->Protocols->TCP/IP-
>properties->WINS addresses, and select the "Enable LMHOSTS Lookup"
10.1.1.1 example1 #PRE #DOM:mydomain
10.1.1.2 example2 #PRE #DOM:mydomain
With the above LMHOSTS file entries, a computer would attempt to use the IP
addresses 10.1.1.1 and 10.1.1.2 to log on to the domain called mydomain.
