SCCM: SUP is not working due to WSUS crash

Interesting case – WSUS built for SCCM SUP crashed regularly. It started from once in a month, after that more and more often and finally WSUS application pool could not stay and hour. Recommended solution was to recycle WSUS application pool. But that was not really a solution since permanent monitoring is required.

It turned out to be a known issue for SCCM 2012 (looks like SCCM CB is affected too) and Microsoft recommends to enlarge App Pool private memory to 4 (or in some cases to 8!) GB. Sounds a bit crazy for me but at least WSUS is up and running now.

SCCM: Clean encrypted drive before TS start

One of my Customers happens to have a McAfee encrypted drives on Laptops and Desktops he plans to migrate to Windows 10. Unfortunately McAffee version was not cooperative with SCCM and he was ok to clean the drives.

To achieve that I added a file called diskpart.txt on my file server (where my Network Access Account has access)

The file contains two lines:

Select disk 0
Clean

After that I customized the boot image by adding a pre-start command and pointing the boot image to the shared folder containing my configuration file:

image

The script is invoked after you press ‘Next’ on OSD dialog logon page but before you select any Task Sequence.

Did the trick for me.
