I am hoping someone out there has an answer for me.
We have 1 user that is prompted to enter his domain credentials when he opens IE to connect to our Sharepoint site. Once he enters his credentials, he gets in fne. Once he closes all instances of IE, he is again prompted to enter his credentials. The challenge box does remember his username, if that means anything to anybody.
This started about 2 weeks ago. He received a new PC about 6 months ago and had no prior problems with this. The PC is running XP SP3 with all current patches and IE8. When this started, we suspected a corrupt profile, so we recreated the profile and the problem went away until today. Our Sharepoint site is listed under the local intranet zone and when on the site it is recognized as being local intranet. Also, the radio button under the security settings is selected for Automatic logon with current username and password. We have also tried Automatic logon only in Intranet zone, but that does not change the outcome. We use proprietary point of sale/sales lead software that has our Sharepoint site embedded in it, so using a different browser is not an option..
Is there anything that you can think of that we might not have tried or any idea as to what might be causing this?
Thanks in advance for any thoughts.
