samba - Feb 1998 - Invalid NBT packet

I get the following error when trying to mount a Windows 95 machine
from my Linux machine (RedHat4.2, 2.0.30) [Samba version 1.9.16p11].

smb_get_length: Invalid NBT packet
smb_dont_catch_keepalive: server->data_ready == NULL
smb_dont_catch_keepalive: server->data_ready == NULL

My command line argument is:

$ smbmount //printser/test /mnt/test

I have also tried -c, -U, -P options and get the same message. Is this
a problem on my Linux machine or on the Windows side. The directory I
am trying to mount is D:\test, which is shared.

TIA.
