CCMexec stops right after it has been started

I my environment, I suddenly had a lot of inactive clients. I thought that it was strange, so I dived into the issue.
Looking at a client, I found that the ccmexec service wasn't running.
I started the ccmexec service, but it stopped immediately (later I found that, on other client the service stopped after 5 minutes - they would start a repair, and then fail and stop).
Then I looked into the ccmexec.log and found this:
Service settings instance is missing from WMI.

Error loading service settings. Code 0x87d00218 Phase 0 initialization failed (0x87d00218). Service initialization failed (0x87d00218). Shutting down CCMEXEC
x

I tried a repair, but that didn't solve the problem.
Taking a deeper look into the log told me that the client had a problem with the ccm part of wmi.
I then tried to do a client push with the uninstall option checked - and now... Happy client again.

Looking at all my inactive clients - suddenly 10-15% og my environment - it seemed like this issue happened during the upgrade to 1602.

Reinstalling Management Point fails with "Not enough disk space" on SCCM 2012 R2 SP1 CU1

I have a SCCM server (level: 2012 R2 SP1 CU1) with SMS Provider- and Management Point role installed.
After upgrading WAIK to version 10, a reinstallation of all roles were initiated.
All roles installed fine - except for the Management Point.


Looking into MPSetup.log I found:



PreReq fails !!! ok, we look into CCMSetup.log:

Ok, the client installs ok, but the update fails with.... Not enough disk space - The installation requires at least 90MB free disk space ...
I have plenty more disk space than required....


Ok, I removed the MP role - and added it again.... same error...


After several hours of troubleshooting it turned out that there was a mismatch between the MP and the client version, that the MP tried to install (thanks to Microsoft Support and Kent Agerlund @ Coretech).


To solve this issue, I had to follow these steps:
1 remove the MP role from the server
2 uninstall ccm agent (ccmsetup /uninstall)
3 restart the server (just to be sure...)
4 install the MP role (this also install a sccm agent)
5 upgrade the sccm agent (ccmsetup /upgrade)


YES... now my MP was up running again.
(but the error message was SO far from error as it could be)
