How to use nslookup tool to identify services, computer, etc..

http://support.microsoft.com/kb/200525 Looking up Different Data Types To look up different data types within the domain name space, use the set typeor set q[uerytype] command at the command prompt. For example, to query for the mail exchanger data, type the following: C:\> nslookup Default Server: ns1.domain.com Address: 10.0.0.1 > set q=mx > mailhost Server: ns1.domain.com Address: 10.0.0.1 mailhost.domain.com MX preference = 0, mail exchanger = mailhost.domain.com mailhost.domain.com internet address = 10.0.0.5 > The first time a query is made for a remote name, the answer is authoritative, but subsequent queries are nonauthoritative. The first time a remote host is queried, the local DNS server contacts the DNS server that is authoritative for that domain. The local DNS server will then cache that information, so that subsequent queries are answered nonauthoritatively out of the local server's cache.
