Locating the problem....Just like other people, I have searched everywhere to identify the real problem but most of the people were having a problem during trying to get the User Profile Service Sychronization job started. My issue was different from these because my environment was perfectly working fine without any issue. After I got this error, I went back and traced what was done to the SharePoint servers. I realized that I downloaded SharePoint 2010 Auguest 2010 Cumulative Update (CU) and ever since both CUs for Foundation and Server 2010 have been successfully installed, I started getting the error messges.


Solving the problem.....So, I created a farm backup and tried deleteing a SA for User Profile Service and re-created it. If you have My Sites created by your end-users, the My Sites will not be accessible until you re-create the SA (and don't worry, all contents in My Sites will still remain the same even though they look like they are gone). You should also expect that any profile edits made by individuals on their My Profile will be wiped out. After I re-created the SA for the User Profile Service, my error messages gone and my server shows no error. If you run into this similar problem and have a trouble getting the User Profile Service re-created or re-configured, please leave a comment! Good luck!
