Unable to authenticate with PDC

By steffeno ·
Hi all, I will try to make this short.
1. There is 2 site with 2 servers running NT 4 with SP6a.
2. Site A is where the PDC is located.
3. Site B is where the BDC is located.
4. What I am trying to do is to decommission the BDC and allows user authentication through the WAN link.

A couple of things I have tried.
1. I have checked the WINS and everything is fine. the 1B and 1C records points correctly to the PDC.
2. Tried setprfdc from the resource kit but no luck. Logon server is still the BDC.
3. I analyse the network packets on both end. Seems like it reaches the PDC. But there's not much information there as well.
4. Tried adding lmhosts instead of using WINS. but no luck as well.

Can anyone help?

First of all it's good practice to have a PDC/BDC combination. If your PDC dies you can promote the BDC.

Secondly, If the WAN link goes down you can use the BDC to authenticate.

However, skipping all of that if your BDC is still UP then yes, it will authenticate the users simply because it's closer (in subnet terms) to the source of the authentication request.

Turn the BDC off and you should find they use the PDC.

Thanks for your answer, but the reason why I put this question here with 500 points is because after shutting down the BDC, the clients is not able to authenticate with the PDC.
