Windows2000 Authentication Issue

By allan ·
I've just installed a firewall and now have a strange problem.
From a server in the dmz, I could not browse or map a drive to machines on the inside. I opened up the interface to "IP Any Any"
-still no good
NT4 domain, so I put a BDC (also a WINSserver on same box)in the dmz to help authenticate.
Now dmz servers can browse and map drives into the inside.
What is not working....On a W2K server, when you choose a folders properties and want to add someone from the domain it says that it can not find the domain
NT4 servers in the dmz do not have this issue
It seems to be a communication problem from the W2K servers to the NT4 PDC or BDC.
There are no problems logging on to the servers so I know they can communicate on that level. Itjust when you try and change File/Folder security that it can not find the domain.
Any ideas ?
Thanks in advance -Allan

Have you joined the NT domain on the W2K mahcine?
Are you logging on localy or onto the Domain?

The issue was not an NT communication problem but was an issue with the firewall configuration. The IP alias in the DMZ created the problem.

Assuming the Win2K server is a member server of your NT4 domain, then I suggest you read Technet article Q180094:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q180094
(please remove any spaces)

This article tells you how to set up the LMHOSTS file on the Win2K box for domain authentication. YOu will add 2 records in the LMHOSTS file, pointing to the IP address of your NT4 PDC.

hope this helps
