HI!
I had similar problems when connecting to an old SAMBA server running on UNIX .
It was that NT didn't agree to send the login credentials in clear text, as was required by the old SAMBA.
The solution was to upgrade the SAMBA or to change the registry on the NT machines, I did the second even so it is less secure.
Try this on your NT machine:
REGEDIT4

;Subject: Registry file to enable plain text passwords in NT4-SP3 and later
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Rdr\Parameters]
"EnablePlainTextPassword"=dword:00000001
And here is a Win9X version, in case you also have problems with win98/ME:
REGEDIT4
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VNETSUP]
"EnablePlainTextPassword"=dword:00000001
Bye
