Hi!
At the site where i work we experience a strange problem, when the PDC goes down for some reason the users can not logon anymore (they can logon with cached credentials though, but not a "real" logon) with authentication from a domain controller.
Our WINS servers are still up and running though, so i canīt see a problem there (but havenīt investigated that much yet).
Do you know of any things that can couse this? So i have something to start looking at (as i canīt really come up with much to check at otherwise).

Perhaps quite common but normal? The very reason for having BDC:s is that they can authenticate users, as it is now here at the site it seems that we have a single point of failure for logons.

No there is no need for arguing, we both now the reason for BDC:s of course, and both want it to work (even though it might be common that it doesnīt).
I have heard a lot about WINS beeing more secure on Windows 2000 servers than NT4 ones (which we currently use). Do you think that it could be a problem and that we should migrate?
And what action do you think that should be taken to "manually fix the wins data for your domain"? Delete the records of the crashed PDC from the WINS database and let it register itself again when it comes back online?
And last but not least, have you tried to script anything which takes care of the manual change in the WINS database to get it working?
(as i sidenote i can say that we have a LOT of WINS servers in the enterprise, a whole lot more than Microsoft recommends so we have a big and complex replication which occurs here)

if your PDC goes down you must immediatley promote a BDC to take its place
This should not necessarily have to be done unless i need write access to the SAM database. For user logins everything should work, in theory anyway. If it doesnīt i think that something is wrong in the setup, thatīs what i think that we have somewhere. Either that or buggy software.
