HI, We found the below error in ccmexec.log The CCM namespace does not exist. Repair required. Detected faulty configuration. Repair will be started in 5 minutes. Entering main message loop. WM_QUIT received in the main message loop. Shutting down CCMEXEC... UninitCommandExec failed (0x800401fb). Error invoking shutdown system tasks (0x8000ffff) Waiting up to 2 seconds for active tasks to complete... Error waiting for tasks (0x8000ffff), will shut down anyway. We have renamed the repoitory folder and it did not help. Please let me know the possible solutions. Regards, Boopathi S

Is this on a Site server or Workstation? Have you look at WMIRepair? (You can downlaod WMIRepair from MS download site)http://www.enhansoft.com/

if it is Workstation , i would just to use the Chris Zander tool to repair the WMI and repair the client .

Did you run CCMClean on the client and reinstall?Sabrina TechNet Community Support
