I am studying the packets that are exchanged between RPC Proxy Server and
Backend Exhange Server 2003 (in a RPC over HTTP deployment)
I have been reading the NTLM authentication methods and have used the
challenges given by exchange server to create LM/NTLM responses. These
responses are not like the ones that are observed in the actual
communication. I have used the codes in SMB auth files and their response is
different.
Anyone who can point out the difference. The ethereal recognizes the
originial communication as NTLM challenge response mechanism and the
responses are of 24 bytes. However their value is different. What is the
cause? Has Microsoft changed the Algorithms when two Windows 2003
communicate with each other or what else?
