Error 401, Unauthorized - authentication failed

[Scott M.]

On an NT 4, sp 6 pc with IE6 (all updates & service packs
applied), when going to a web site logged into the pc as
User A I get the "Error 401, Unauthorized -
authentication failed" message. However, when logged in
as User B, I can get to the site just fine on that same
pc. On a different pc User A can get to the site just
fine. Is there some property within Internet Explorer
that needs to be changed?

I can be reached at (e-mail address removed) for replies to
this. Thanks.

Go to Tools, Internet Options, select the Security tab,
select the Internet Zone, Custom Level and scroll down to
the User Authentication section. Under Logon, make sure
it's set to "Automatic logon only in intranet zone." It
was probably set to "Anonymous Logon" and if a site
requires a user name & password, it will fail if set
to "Anonymous Logon".
