samba - Feb 2002 - Samba 2.2.2 + NT problems

I am having a problem with samba 2.2.2 and an NT workstation.

Basically, when it's trying to log on to a guest OK share, it keeps 
asking for username and password.

Here's the log files on the file server:

[2002/02/12 11:12:51, 0] lib/util_sock.c:write_socket_data(542)
  write_socket_data: write failure. Error = Broken pipe
[2002/02/12 11:12:51, 0] lib/util_sock.c:write_socket(566)
  write_socket: Error writing 156 bytes to socket 26: ERRNO = Broken pipe
[2002/02/12 11:12:51, 0] libsmb/clientgen.c:cli_send_smb(89)
  Error writing 156 bytes to client. -1

and on the password server:

[2002/02/12 10:11:49, 0] lib/util_sock.c:read_socket_data(478)
  read_socket_data: recv failure for 4. Error = Connection reset by peer
[2002/02/12 10:11:49, 0] lib/util_sock.c:read_socket_data(478)
  read_socket_data: recv failure for 4. Error = Connection reset by peer


I'm not sure what SP this particular workstation is on.  It's one of 
those "proprietary NT printer servers" and only the factory has access
to any of the system / config stuff.

Here's the share that we're having a problem with:

[public]
    path = /var/tmp/public
    browsable = yes
    comment = Public temporary directory
    writable = yes
    guest ok = yes
    create mask = 777
    directory mask = 777

All of my other workstations can access it fine, but this is the only NT 
box on the network.  All my other workstations are win9x/ME.
