Troubleshooting NetBIOS Name Resolution Problems

Use NbtStat to verify that you have the right IP address for a specific NetBIOS name is to use a tool that displays protocol statistics and TCP/IP connections using NBT (NetBIOS over TCP/IP). The syntax is case sensitive. For example, nbtstat -A lists the remote computer name table when given its IP address, and nbtstat -a lists the remote computer name table when given its name.

Examples of NetBIOS name resolution problems:

  1. You can ping another computer, however Nbtstat believes it is a computer other than the one that you specified. This means that there is a problem with name to address mapping. (An Nbtstat result overrules a Ping result.)
  2. You cannot ping another computer, and you receive a "Bad IP Address" error. This means that the name cannot be found.
  3. You cannot ping and you receive a "Request timed out" error. This means that either there are name resolution or connectivity problems or that the server is not functioning.
Using Nslookup for Name Resolution

You can use Nslookup to perform DNS queries and to examine the contents of zone files on local and remote servers.  To use Nslookup in interactive mode and to verify name resolution, at the command prompt, type the following:  NSLOOKUP
