This works perfectly in both directions. No errors at all.

Even though the other machines are not all the time on line? Remember that
the only machine that is 'always' on is the W2K3 server.
Is this not contradictory to the fact that we have disabled on all
workstations the 'computer browser' service?

That's exactly how it is.

That's new for me, I was not aware of the existance of a DMB (Domain Master
Browser right?)
Can this be configured apart from the SMB in w2k3 server, and how to do so?

I only know a little bit of subnetting, I understand that the second portion
of an IP address determines the subnet, but I don't know what name is
assigend to a subnet. Where can I find that? Note that our network is Class
B and, correct me if I'm wrong, each machine is on another subnet because
the third octet of the IP address, assigned by DHCP from the w2k3 Server, is
a different number. I don't know what name would be used in Browcon to
differentiate those subnets.

I hope my questions make sense, sorry but I'm not an expert in subnets and
this level of TCPIP.

Thanks for your patience,
Perry
