WinNT 4.0 SP3 and Samba 1.9.16p11

[Gary Jackson-CVUK Coventry +44 1203 417718 x428]

I've just installed Samba 1.9.16p11 on a Sparc2 running Solaris 2.5 and
can connect from Win95 and DEC Alpha WinNT Server v4.0 (SvcPk 2) clients
with full support but I cannot connect from my Intel WinNT Workstation
v4.0 (SvcPk 2 and 3) clients! Any attempt to map a drive responds with
"The network path was not found"! I can ping and telnet the server but
cannot connect and browse it. I've also tried specifying the server in
the lmhosts file to no avail.

Any ideas?

Regards,

    Gary.
