Im not pretty sure but you may need to have a WINS server if the IP Address you are looking up is in a different subnet. I think you are able to get it right if you try an IP within the same subnet?

Hi,<br />
<br />
I'm trying to determine NETBIOS names from IP addresses on a network that does not run AD, it's a Novell network. I'll run GFI LAN Guard on a subnet and get quite a few PCs that don't have NETBIOS info displayed. I'll run NBTSTAT -A (IP ADDRESS) on the IPs that don't display NETBIOS information in LAN Guard and get a &quot;host not found&quot; message. The PCs are turned on, I can ping them, but no NETBIOS info. What might be turned off? We don't run the Windows Firewall. I'm pretty sure all the Microsoft services are turned on, ie. File and Print Sharing, Client for MS networks. Could NETBIOS over TCP/IP be shut off? Is that default?<br />
I've included a screenshot of the CMD screen when I use NBTSTAT.<br />
<br />
Thanks,<br />
Mike<br />

NBTSTAT not returning netbios names

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols
