Hi.
Got a problem here.
Having installed and configured an intranet SharePoint v2 on a server with local user accounts, I showed everything to the site administrators and everything worked fine using Windows Authentication with Anonymous turned off. However, the restricted users have to repeatedly enter their credentials every time they access any SharePoint item, list or library within a single session. When a user has entered their username/password correctly at least once per site, they can press Cancel in the logon box which helps get to the content more quickly. The IIS logs show ISAPI authentication errors when trying to GET /_vti_bin/owssvr.dll (401.5) for users running Internet Explorer 6 SP1 and alternating 401.1 / 401.2 when trying to get any /Lists/List/view.aspx followed by code 200 if the user has enough persistence or impatience to either repeatedly enter their password or hit Cancel in despair. Filemon shows that all file requests at the time of 401's return with success, so probably NTFS permissions are not to blame.
The server local restricted users granted the right to manage site separately or by inclusion in the Administrator site group do not experience this problem - they authenticate once and continue working normally as expected.
This post is not about automatically authenticating users without asking for credentials even once (save the local machine logon), but rather helping them to use SharePoint without this annoyance.
Any help finding the solution without employing AD would be appreciated. Authentication methods other than Windows Authentication are disabled.
Thanks in advance,
