Reinstall of SCCM 2012 (information required)

Recommended Posts


Before I start, I’ve never installed or used SCCM 2012 or previous version!

I’ve just inherited access to an existing SCCM 2012 install for work and I have no information about said install. I have no idea how the install was handled (done by the previous IT staff that left the job), the joys of IT! As far as I can make out we are running 3 servers, one CAS, one Primary and I’m not sure on the other (possibly something to do with SQL).

I can only really see one solution to my current problem and that’s to wipe the images and start from scratch.

I’d just like to know if there is anything I need to do before I carry out a wipe and full re-install. I’ve had a look around for prerequisites for a full uninstall, the only information I can find regards the SQL database.

SCCM 2012 Database:
• Delete your old SCCM 2012 DB from the SQL server.

SCCM 2012 Local User and Groups on SQL Server:
• ConfigMgr Remote Control Users
• ConfigMgr_DViewAccess

Registry Key on SQL server:

SCCM 2012 Service on SQL Server:

Is there anything else I should consider before attempting this?

I’m planning on going through the Standalone Primary Server install once I have prepped everything.

Now I’m off to buy some rubber rings for my trip to the deep end of the pool!
