We here at ArmgaSys have started to see a high incident rate of User Profile loading failures. These failures have different symptoms, but exactly the same root cause.
Symptom #1: The never ending logon
This symptom is classically described as:
- You sit down in front of a PC you have logged into every day since you started work
- You enter your user name and password
- You are greeted by the “Welcome” screen
- You watch the “Welcome” screen spinner for hours…. and hours… and hours….
Symptom #2: New profiles can’t be created
This symptom is classically described as:
- You have called your client services folks over because of the never ending logon
- Your client service guy (or gal) logs onto your PC with their administrative account
- They receive the always entertaining “The User Profile Service service failed the logon. User profile cannot be loaded”
Symptom #3: The event log
Upon reviewing the PC’s event log (which any good Client Service team will do) reveals:
Event 1509, User Profile General
WIndows cannot copy file \Users\Default\AppData\Local\…\sqm-data[SEQUENCE].sql to location [A profile location goes here]
This error may be caused by network problems or insufficient security rights.DETAIL – Access is denied
Root Cause
The Software Quality Metrics software instrumentation system flubbed up a file in your user’s profiles.
We see this a lot in Visual Studio installs (VS2010 – VS 2013) but have noticed an increase in other Microsoft products.
How to fix
It is simple! Find and delete the SQM files listed in the event log
-OR- (The more draconian approach)
- Navigate to C:\Users\Default\AppData\Local\
- Search for *.SQM (all SQM files)
- Delete them!
Good luck!
