Integrated Authentication Issue

[Kevin Olsen]

I have a web application using asp.net that uses
integrated windows authentication. One of our users
changed their windows login information.

The problem I'm having is that asp.net seems to be
receiving the old user ID (found in Request.ServerVariables
["LOGON_USER"]). The odd thing is that the web logs show
the correct user ID.

This user does have the .net framework loaded on the pc.
Is there something on the PC that is causing it to send
the incorrect authentication information and how can I
clear that?

Also, is there another way I should be retrieving the
LOGON_USER from the client?

Thanks for any help.
