NTLM is a challenge response protocol. That means the client needs to make a connection containing a challenge and the server makes the response. No user name and password are ever transmitted to the server - the authentication takes place with the domain controller.

Like I say. I have never written an NTLM authenticator in VB and I do not plan to either. That doesn't mean the its not possible, just that its a complex and time consuming task.

If you want to do it yourself here is a detailed specification.
