NT_STATUS_BAD_NETWORK_NAME
On the other hand, if you're getting this sort of issue:
# smbclient //192.168.0.14/I/
Enter root's password:
Domain=[WINPC_NAME] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME
#
Then tips on this Samba / CIFS Connectivity page may help.
