I would like to ask for support regarding this problem. We have several users (Windows Xp & Windows 7 users) who are accessing our SharePoint site, but everytime they access the SharePoint site, the site is asking for their Usernames & Passwords, but we already set the SP to be Windows Authenticate. So every users can just open the site & they're automatic logon to the site. But some users, specially for 2-3 Windows7 users, the program is asking for the credentials & username & password. So, they'll just click the OK button 3x, then it'll be gone. But after some time, it'll pop up again...
Kindly advise on how to resolve this matter.
