Task Scheduler MMC - Red Stop Sign

Hi Experts,

I'm not sure how long this has been an issue. However, when opening the Task scheduler we now get a red cross when opening it from the mmc.

It doesn't list any tasks and has occurred across 3 of around 10 of our servers.


It may have been the latest windows updates we have put on, however the task scheduler hasn't been checked after patching.

Has anyone seen this before?
What is my first step to troubleshoot this?

This is Windows 2008 R2, no Service Packs currently.

Thank you.

This could be corruption with the mmc addin.

Try moving the files from %AppData%\Roaming\Microsoft\MMC to another location to clear out that folder and retry.

Thanks for the quick reply!

I've removed the items. I've now tried to load the task scheduler again however now still showing.

Expand: Loading task folders...      is showing at the bottom of the window.

No other files have appeared in the %AppData%\Roaming\Microsoft\MMC either.

Thanks again.

To add to this, when I try to goto Local Users and Groups, Group, Double click Administrators. This is now crashing the MMC too.

There is a know bug with Server 2008 and the MMC, to which Microsoft have released a hotfix for. That may assist you in a resolution.

Additionally, any information from the event log regarding the failure of the MMC would be useful.

Thanks.

The hotfix is relating to ADUC, I'm talking about local users and groups on this server.

Thanks though!

This is an error I had when the MMC crashed:

The program mmc.exe version 6.1.7600.16385 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.
 Process ID: 1330
 Start Time: 01cd08e22c8705a3
 Termination Time: 47
 Application Path: C:\Windows\system32\mmc.exe
 Report Id: 141ce03f-74d7-11e1-8328-005056a31ef7

No other issues reporting about MMCs not loading though.

Nothing obvious there. Does explorer hang at the same time?

Have you also moved the files back into the %AppData%\Roaming\Microsoft\MMC that were removed during the testing earlier?

Is the server 32bit or 64?

Can you open the task scheduler using the following command, either from a command prompt or the run box.

%SystemRoot%\system32\taskschd.msc /s

This is 2008 R2, so 64bit.

Running %SystemRoot%\system32\taskschd.msc /s  gives the same erroneous result.

I have now put the files back into the directory and again, same result.

Explorer doesn't seem to hang at all throughout the problem.

Thanks again for your help.
