1. After many years, I've learned NEVER to use anything but A to Z and 0 to 9 in the name of the server. You can gripe about this to Microsoft, but this is what I've learned and I'll share this.

2. You didn't mention the NT 4's condition. Did you reapply SP6 and all patches since then?

3. Did you reapply SP6 on the NT 4 box? It's not "sticky" and any changes you make sometimes will undo a patch.

4. No mention of adding the user to the NT 4 users?

5. Mappings and such may indeed vanish. You often find that login scripts are needed.

Sadly, I can't help too much with NT 4.0 anymore. Due to the security problems that Microsoft left unpatched, our last NT 4.0 servers and workstations were removed some months ago. I will NOT be able to duplicate much, but will share from my prior years of running NT 4.0 servers and workstations.
