Displays protocol statistics and current TCP/IP connections using
NBT(NetBIOS over
er TCP/IP).
NBTSTAT [-a RemoteName] [-A IP address] [-c] [-n]
[-r] [-R] [-s] [S] [interval] ]
| -a (adapter status) | Lists the remote machine's name table given its name |
| -A (Adapter status) | Lists the remote machine's name table given its IP address. |
| -c (cache) | Lists the remote name cache including the IP addresses |
| -n (names) | Lists local NetBIOS names. |
| -r (resolved) | Lists names resolved by broadcast and via WINS |
| -R (Reload) | Purges and reloads the remote cache name table |
| -S (Sessions) | Lists sessions table with the destination IP addresses |
| -s (Sessions) | Lists sessions table converting destination IP addresses to host names via the hosts file. |
RemoteName Remote host machine name.
IP address Dotted decimal representation of the IP address.
Interval Redisplays selected statistics, pausing interval seconds
between each display. Press Ctrl+C to stop redisplaying

Note: NBTSTAT commands provides some information that might be misused by somone in the sense that it provides 2out of 3 of the information necessary to connect to a computer. Yet, a very useful command for those who use it.
