User credential issue in SharePoint Site

Hi all,

Today, I'll talk about an strange SharePoint issue, but it's not an issue from SharePoint.

It's a client side issue.


Facts:
 - User is Site Collection Administrator

 - User gets popup to enter his login/password (credentials) when accessing to his SharePoint Site

 - Login & Password are correct

 - Login to his SharePoint site from another computer is working (this is the first test I've asked the user to do and provide me his feedback)

Solution: Check the user credentials on your computer:

 - Click on Start

 - Control Panel

 - User Account

 - Credential Manager

 - Remove from Vault all references to SharePoint sites

Possible reason:
 As company policy, we must change our password several times per year.
 I bet that Windows kept (for this user) his old password in cache, thus replacing automatically his credentials by the one stored in the Credential Manager.

That's all folks
