Tasks is not running as scheduled. Couldn't run it manually either. It seems to hung and doesn't give an error message to trace the problem. I have gone through all the steps mentioned on every nett but doesn't help to fix the problem yet. The scheduler service is also grayed out and it's not possible to restart it after every small changes. It's difficult to boot a server in prod every time things are changing. Any one who came accross this issue and can give me a solution?

Hi, do you receive any error if you use CMD (run as administrator) and "net start schedule" to start Task Scheduler service? Have you tried run services.msc as Administrator to start the service? •Click the Start orb •Type Services in the Start Search box •Right-Click Services, and select Run as Administrator If you are prompted for an administrator password or confirmation, type your password or click Continue •Right-click the Task Scheduler Service and select Restart If this does not fix the problem you may want to use the System File Checker tool. Please follow the instructions below. To run the System File Checker tool, follow these steps: Click the Start orb, and then type cmd in the Start Search box •Right-click cmd in the Programs list, and select Run as administrator. •If you are prompted for an administrator password or confirmation, type your password or click Continue •At the command prompt, type the following line, and then press ENTER: sfc /scannow If the issue still occurs, you can run the following command and let us know the result: cmd /k sc qc schedule Hope this helps!Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hei, Thanks a lot for your reply. I have done just like you have mentioned but the problem still exists. Task scheduler service is running and configured to run automatic. But can not be configured manually either to stop, start or restart. It's grayed out. I have to boot the server to be sure that the service is restarted after I make changes which requires restart of the service. I run command line as administarator and tried to stop the service, net stop "task scheduler" but got a message "System error 5 has occured. Access is denied" I run the command line as administrator and run sfc /scannow. The verification completed with this message "Windows resource protection found corrupt files but was unable to fix some of them". It generates a log file under C:\windows\Logs\CBS\CBS.log I run the command line as administrator and run cmd /k sc qc schedule with the following result C:\>cmd /k sc qc schedule [SC] QueryServiceConfig SUCCESS SERVICE_NAME: schedule TYPE : 20 WIN32_SH START_TYPE : 2 AUTO_STA ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\Windows\s LOAD_ORDER_GROUP : SchedulerGro TAG : 0 DISPLAY_NAME : Task Schedul DEPENDENCIES : RPCSS : EventLog SERVICE_START_NAME : LocalSystem I appriciate your generous reply!TGB

Hi, since the issue can be caused by corrupted files during SFC/scannow, you can upload the CBS log for further research. For your convenience, I have created a workspace for you.

Ok, I have already sent the log file. Thank you!TGB

Hi, below is what I found in the CBS log: 2011-07-12 10:39:41, Info CSI 00000128 [SR] Could not reproject corrupted file [ml:520{260},l:88{44}]"\??\C:\Windows\security\msscw\TransformFiles"\[l:32{16}]"scwvariables.xml"; source file in store is also corrupted 2011-07-12 10:43:34, Info CSI 00000191 [SR] Could not reproject corrupted file [ml:520{260},l:88{44}]"\??\C:\Windows\security\msscw\TransformFiles"\[l:32{16}]"scwvariables.xml"; source file in store is also corrupted You can try replacing the file on a working Windows Server 2008 computer or perform a In-Place Upgrade on the computer: How to Perform an In-Place Upgrade on Windows Vista, Windows 7, Windows Server 2008 & Windows Server 2008 R2 http://support.microsoft.com/kb/2255099 Regarding the Task Scheduler service issue, I suggest you check the following solution: (Note: remember to backup the registry entry before you modify it.) 1. Open your registry, Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Schedule 2. Find the REG_DWORD called Start. 3. Modify the setting and change it to 2. 4. Find the REG_DWORD called Type. If it does not say 20 (hex) 32 (dec) then change it. 5. Close the registry, and reboot and see if it works.
