Hey Hey,

Question for ya phish... you said

The NT 4.0 File server host name is "fileserver"
That's the hostname or the NetBIOS name.. or both? to ensure that it's the netbios name run net user on the NT machine and see if you get \\fileserver at the top...

the reason that the ping would work is because it's using IP.. so it's going to use DNS... since there's no . after fileserver it's automatically going to append .domain.com (the origin)... (if you look in your options on your machine you're pinging from... in advanced you'll see the option to append this domain)... it's automatically filling it in for you. The reason it works with the full address is that it resolves without problem...

when you just type fileserver with net use... it's going to use netbios.... Is NetBios blocked on the network... is NetBios blocked on that machine... Do you perhaps want a WINS server (since you've got NT4) setup... that will translate the netbios name into an IP Address

I'm wondering (and I dunno... NT4 was before my time)... do you have NetBIOS on NT4 and NBT on 2K/XP... and that's causing problems??? I would't think so.. but it's a thought..

I'll keep pondering it.

Peace,
HT

Damn it... beat to it on the WINS point.... I should stop doing any real work and commit myself to AO
