Sharepoint Requires Authentication

Our corporate intranet is on Sharepoint Foundation Server 2010.  It has been working fine for since February 2011; however, recently a small number of users (3 of 600) are being prompted for authentication credentials when browsing to the site.

The users are using IE9, no plug ins or add ons.

We have tried rebooting the client computer, resetting the browser to factory defaults, deleting temp files, and clearing cache.  The site is in the intranet zone (defined by group policy).  No particular update seems to have caused this issue.

do you have ISA or TMG installed
if yes check the exception list on the browser connection settings
also you can try remove/add those workstation from domain
Go to internet properties, click on security tab, go to custom level scroll to the bottom, in the logon section check use current username and password.

No.

Already checked.

Again was working for 8 months without issue.  No real significant network/server changes.
it is a internet explorer 9 issue. I had the same problem.
Have you tried a different browser?

DOes this happen if the user goes to another compuer? I would think it will not follow the user. this would equate to a local machine authentication issue try to run  control keymgr.dll and see if you have credentials

Check out the credentials section here and see if this helps:

45% of our user base uses IE9 (about 250 users).  3 have this issue.  If it were IE9, all users would have this issue.  I have IE9; no issue for me.

>DOes this happen if the user goes to another compuer?
Good question.  I doubt it but will find out.
So you're saying these users were able to go into sharepoint before without being prompted, or are these new users?

Any chance these user's password has been cached by the browser, the users have changed their passwords recently and the browser is sending the wrong password? Try clearing saved passwords from their browsers.
>you're saying these users were able to go into sharepoint before without being prompted
Yes

>Any chance these user's password has been cached by the browser
Seems unlikely given the troubleshooting steps outlined in the problem description.
Are their workstation clocks off from the domain server / SharePoint server?
I'll check.
I too am experiencing this annoyance. SharePoint Foundation 2010 was recently deployed and my users are reporting this annoyance daily. The quirk is they never lose connection to the site they are accessing. They select cancel when prompted for credentials, refresh, and the site page remains.
I have implemented the AuthForwardServerList reg hack (NG). In addition the url to the server has been added to the intranet zone also no success.
I also believe the issue to be related to IE9. This is hard to believe since we are taalking about Microsoft products across the board. I have tested using Chrome, FireFox, IE8 for a few days now and I am never prompted for credentials.
If anyone out there has further insight please post.

One of the embedded images was pointed to the external DNS mapping for the internal domain (ex.  internal domain is domain.local, external domain is domain.com.  The image was on server.domain.com, not domain.local.)

When I change the mapping of the image to server.domain.local, the issue disappeared.
None of the images (few that there are) that are present on any of the sites in question are pointing to any external domains.
Pgroup374, this is not your question.  Open your own question if you want someone to solve your problem.  You cannot hijack a question and object to a close because its not your solution.
my apologies
If they are being constantly asked to enter their userid/password and never make it to the first page, then we also had the same issue, I found that the network policies were mixed and the "bypass proxy for these sites" had the sharepoint website listed in it for some users but not for others, it was difficult to see this as IE had been locked down and you could not actually see what they were set to.

As this was an intranet SharePoint 2010 environment any user that was being re-directed through the proxy was constantly being asked to enter their credentials, not sure what proxy we were using but I did find other articles that pointed out some proxies just won't work with passing credentials through automatically.

The effected users were not receiving policy updates on their machine, do a roll-out of policies and ensure you add your sharepoint server to the bypass proxy setting in IE for all users. Or manually change this on the effected users pc.
