Weird Problems - Name Resolution??? 2

[Mighty]

We have two NT Servers and the BDC crashed last week and we had to get a new drive a rebuild it. So we reinstalled the operating system and the service pack and then restored the C drive that was on the old drive from tape backup.

However, since then we are having several problems with client PC's logging in and mapping drives. This can usually be resolved by installing the NETBEUI protocol on the clients. However, we never needed this before.

Can anyone shed any light on this for me??

Are you running WINS Server on the network? I was able to get rid of NETBEUI altogether once I got wins working. (serveral years ago)

Did the crashed server have WINS on it?

Hi Storm,

We do have WINS Server running on the network but it runs on the PDC. The Server that crashed was a BDC. I have the Wins server specified on the BDC to point to the PDC.

However, the WINS service is running now on the BDC. Could this be causing some kind of conflicts?

If you have WINS running on two machines, make sure that WINS replicates with one another. If it does not, you can have problems.

Do you have DHCP installed? Maybe the server that went down had DCHP running...and now that the server died, DHCP is no longer running. You should check your IP settings on the client machines to see if they are connecting properly.

I aggree that you should avoid NetBUEI all together.

-Hope this helps..

In relation to WINS, am I better off to disable it on the BDC or replicate it from the other server.

DHCP is running but seems to be working properly. The problems that we are seeing is that mapping drvies on the BDC is requesting passwords even though the users always had access to them. THe permissions are set up correctly on the shares.

Also on some clients, you can only log on as administrator or as a user that has been logged on to that pc before. If you try to log on a new user, it won't allow it. However, after installing NETBUEI this worked.

I'm at a loss as NT admin is not my strong point.

You should replicate WINS for redundancy. (You need to check you DHCP settings to see if 1 or 2 ip addresses are being handed out by WINS. If two ip addresses are being handed out, you need to make sure replication is working between your two WINS servers.)

You really need to validate whether DHCP is working properly. Print out all of your settings being handed out by DHCP and compare this to a client machine. Make sure that they match up.

The issue is this...you are telling me that things don't work right unless you enable NETBUIE... So, this fact alone, points to an IP related problem. You must make sure that IP will working properly. I would concentrate on this...

-hope this helps...

Turn off WINS on the BDC (or get replication working) and your problem will go away.

Assuming all of the other machines are pointing to the other WINS server it is the BDC itself that is having resolution issues (It is using its own WINS database which has no entries for the other Domain controllers).

Specifically it is probably not finding your PDC, (you should have entries in the event log to that effect).

Then what happens is that it thinks the users are not logged in to the network if they authenticated with the PDC
and so it asks for passwords.

Thanks guys.
Once I got WINS replicated successfully, all my problems disappeared.
