I am trying to connect to a aspx page which is configured with NTLM
authentication using the user name/domain I am logged into in my workstation.

I can log in automatically (not prompting me for credentials since it gets
my login credentials) but the credentials are wrong. During the NTLM
challenge/response IE is telling the server i am user "X" when in fact I am
logged in as user "A".

The only relevance user "X" has is that I logged into a network drive as
user "X".

But I log into my own machine which this is running off of as user"A".

Why does it do this? How do I fix it?
