NTLM

NT Lan Manager

Little history: It was the authentication protocol for the Windows NT and Windows 2000.So it started at that time and is still used but the latest one is windows kerberos (hopefully i"ll dig about this soon.)

What is it: Firstly it is a windows thing.
It is an authentication protocol where you don't have to send ur password out of your system. In the interactive logon you have a domain name,username and a password.After u enter the password your system converts this password into a hash and discards the password.

Meanwhile the system sends the username to the server which generates an arbitrary no. and sends it to your system.Your system somehow encrypts the no. using the hash and sends it(response) back to the server.The server gives ur  username and ur response alongwith the arbit no. to this thing called domain controller which also encrypts the arbit no. with the ur hash(which it will make from ur password) and checks it with ur response.
