The User Profile Service sercive failed the sign-in. User profile cannot be loaded


I had a Windows 2012 server, only the administrator could logon to. Every new login was meet with following message and then rejected.

login message


After looking a bit in the event log – we find entries with id: 1509:


Windows cannot copy file \\?\C:\Users\Default\AppData\Local\Microsoft\Exchange Server\v15\Configuration17788_100.sqm to location \\?\C:\Users\TEMP\AppData\Local\Microsoft\Exchange Server\v15\Configuration17788_100.sqm. This error may be caused by network problems or insufficient security rights.

DETAIL – Access is denied.


What this means – the System account cannot read the Default profile data, therefor unable to create a new user profile. I still have no clue why this happened in the first place.

Go to the Default user profile ( c:\users\default\appdata\Local ) right click on the Microsoft folder –> Security –> Advanced, and check the “Replace all child object premission…..”

Default profile  filepermissions


Try.. no, Please logon now 🙂
