MS-DOS utility that displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP), which allow the user to troubleshoot NetBIOS name resolution issues. Normally, name resolution is done when NetBIOS over TCP/IP is functioning correctly. It does this through local cache lookup, WINS or DNS server query or through LMHOSTS or Hosts lookup.
NBTSTAT [ [-a RemoteName] [-A IP address] [-c] [-n] [-r] [-R] [-RR] [-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 NBT’s cache of remote [machine] names and their 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
