Microsoft has just released a number of new KB articles that describes how to maintenance and troubleshoot software updates in Configuration Manager 2012.

Those are:

Today I had a strange problem.

I was testing OS deployment at a customer and had two test PC's that I was testing Windows 7 deployment on.

At first they could PXE boot and start the Windows 7 deployment but then deployment failed with an error.
I corrected the problem in the task Sequence and PXE booted again and this time the Windows 7 deployment was failing with a new error.

I corrected the error but now I could not PXE boot the computers anymore. When they entered the graphical part of WINPE they just rebooted again.
I checked the MSTSC log file that stated that "There is no task sequences available to this computer".
I checked the ConfigMgr console. Both computers (which was failing) was in the correct collection and they had the Deployment for the Windows 7 deployment.

I then google'ed the problem and found this where they have the same problem. More...

During a ConfigMgr 2012 SP1 client deployment I had problems with one client on a Windows Server 2003.

It seemed like the client installed correctly but it would not communicate with the management point.

I looked in the log files and found the following:

I could also notice that there were no SMS certificates in the local computer certificate store.

I asked Google for an answer to the problem and found several posts like this one suggesting to delete all files in the "C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys" folder and then restart the SMS Agent service. This solution had helped several people but in my case it did not work.

Instead the information here guided me to the solution.

When the SMS Agent host service was restarted it recreated a certificate (19c5cf9c7b5dc9de3e548adb70398402_6ee5afbf-3882-4a52-8ad4-1ef3db2563ee) in the above mentioned folder but it turned out that it had the wrong access permissions. I gave "System" full control to the file and restarted the SMS Agent Host service again and now the SMS certificates were created and the ConfigMgr client could communicate with the MP as it should.

Problem solved......
