login server

[DanS]

In a W2K server and W2K Pro environment with Active
Directory (all SP4), how does a client find a login
server? The reason I'm asking is occassionally we will
find clients in our New York office being logged on by
DC's in our Boston office even though the New York office
has global catalog servers which were up at the time. We
have even noticed Boston clients being logged on by Munich
DC's.

Anyone have any ideas? Thanks!

See this for info. on how Windows NT 5.x clients locate DCs:

This is probably a misconfiguration with your sites. Check, and then
recheck your subnet associations. Ensure there's no typo's, etc. Check
that the DNS server that you're clients are pointing to is local.

The Support Tools tool nltest has some handy tests that may help as well.
For example, nltest /dsgetdc:domain.com, nltest /dsgetsite, nltest
whowill:domain.com userName

Dan,

As Paul stated, take a look at your Sites and Services MMC. He also
supplied you with the link that describes how a Domain Controller is found
( but I think that the link that he gave you was for WIN XP clients; try
this one for the WIN2000 clients -
http://support.microsoft.com/?id=247811 ).

Essentially, a client is supposed to located a DC in it's Site. This is
handled by the SRV records.

HTH,

Cary

That won't affect the logon process.

Thanks for the replies. Problem got increasingly worse
and the domain controllers eventually crashed. Microsoft
came in and uninstalled and reinstalled TCP/IP (among
other things) on the DC's which seemed to fix the issue.
