    I've been baffled by this for awhile now. I have a simple site set up to use
    Windows Authentication, with an allow="*" and deny="?" to allow only domain
    users. The web server is Win2003 and is not exposed to the internet. If I
    access the site with the URL http://myserver/mysite/, I can access it without
    a challenge/response dialog and it picks up my credentials. However, if I
    access the site with the URL http://myserver.mycompany.com/mysite/, I get a
    challenge/response dialog and have to enter my domain credentials. I suspect
    this issue is related to the domain or DNS or perhaps IIS, but I doubt there
    is any ASP.NET configuration issue. Anyone ever experience this problem?

    Thanks in advance!

    Thanks, Brock! That is EXACTLY what I needed. It even gave me the
    justification I need to go to my domain admins and request that this be added
    to our local security policy.
