Windows NT cannot browse Windows Server 2008

Solution 1:

Can I propose an alternative solution?

If your NT4.0 boxen are controlling CNC hardware, I'm going to assume that all you need to do is be able to copy the command files (or whatever).

How about putting IIS on the Windows 2k8 server, then you'd be able to use Internet Explorer (or similar) to browse the file listing, and download stuff from it.

You could even use HTTP authentication backed by the Active Directory to get the user authentication bit.

You've probably got little to no chance of getting a proper file share working, as the protocols have changed so much, probably beyond compatibility, but HTTP 1.1 should still be a possible mechanism.

That said, if you wanted bi-directional file transfers, FTP is still a possibility..

Solution 2:

Another alternative might be to set up a small Linux VM and set up a Samba(3) server. It should be possible to configure it to talk to NT4.

Solution 3:

NT4 SP4 and newer is able to talk NTLMv2 as far as I know, so that shouldn't be the problem.

Basically, two things are required to happen for this to work: 1. Your NT4 box needs to be able to talk to a domain controller 2. Your NT4 box needs to be able to talk SMB with your file server

Could you try the steps outlined in this document? It's basically 4 GPO settings that need adjusting on the domain controller level. I'm assuming the NT4 box is a member for the same domain/forest as the file server. Also any event log entries on your NT4 client regarding unsuccessful domain logons would be of value.
