I know the LOGON_USER server variable will tell you who is logged on, providing anonymous authentication is not running. <BR>I want to know if it is possible to specify an NT Account for a specific ASP page to execute under? I've tried: <BR>response.AddHeader "LOGON_USER","username" <BR>but it didn't work - IIS popped up the user/ID password box. I want to authenticate for this one page but I do not want the user to have to enter an ID/Pass. <BR>Any ideas? I asked this question in the non-advanced & got no answers after 8 hours, so hopefully you won't perceive this as crossposting.
