with nbtstat that allows several options such as: local cache lookup, WINS Server query, broadcast, LMHOSTS lookup, and Hosts lookup. It is not for DNS server query. When a network is functioning normally, NetBIOS over TCP/IP (NetBT) resolves NetBIOS names to IP addresses. It does this through several options for NetBIOS name resolution, including local cache lookup, WINS server query, broadcast, LMHOSTS lookup, Hosts lookup, and DNS server query. The command removes and corrects preloaded entries using a number of case-sensitive switches. The nbtstat -a < name > command performs a NetBIOS adapter status command on the computer name specified by < name >. The adapter status command returns the local NetBIOS name table for that computer as well as the MAC address of the adapter card. The nbtstat -A < IP address > command performs the same function using a target IP address rather than a name. Syntax nbtstat [-a RemoteName] [-A IPAddress] [-c] [-n] [-r] [-R] [-RR] [-s] [-S] [Interval] The common parameters are:< nbtstat -c: displays the contents of the NetBIOS name cache, the table of NetBIOS names and their resolved IP addresses. nbtstat -n: displays the names that have been registered locally on the system. nbtstat -r: displays the count of all NetBIOS names resolved by broadcast and querying a WINS server. nbtstat -R: purges and reloads the remote cache name table. nbtstat -RR: sends name release packets to WINs and then starts Refresh. nbtstat -s: lists the current NetBIOS sessions and their status, including statistics. nbtstat -S: lists sessions table with the destination IP addresses.
