iis: Integrated Windows authentication still pops up account info login

Question

I have a website running on a Windows 2003 server on IIS 6, serving pages for a LAN where everybody is working with a domain account. On other machines this works fine, no-one has to login to the website, the dynamic scripts pick-up the account-name from the HTTP request.

Only, when browsing from the server itself (via remote desktop e.g.), Internet Explorer still pops up the domain-login-dialog when navigating to this site. (both the usual URL and http://localhost/). This was no problem on the Windows 2000 server we recently migrated the website from.

Solution 1

I had this problem or similar and solved it by:

• adding http://localhost to list of Intranet sites, via IE > Tools > options > security > Local intranet > Sites > advanced > add http://localhost. (This is necessary if you have IE Enhanced Security installed which assigns all intranet Web sites and all UNC paths that are not explicitly listed in the Local intranet zone to the Internet zone, even localhost or other domains that don't contain '.' symbol which would normally be considered intranet by default.)

• also on Security > Local Intranet > see what level of security you're on, to ensure that logon details are passed through. If it's Custom then click the Custom Level... button, scroll right to the bottom, under User Authentication > logon > for me it's 'Automatic logon only in Intranet zone', which works.

Solution 2

Did you configure IE on your Windows 2003 box for "Enable Integrated Windows Authentication"? This needs to be configured in IE6 to automatically use the logged-in user credentials.
