In my Lab, I have SCCM and SQL Server on the Same Drive. Recently I have been having issues with Low Disk Space which affected the speed and performance of my SCCM Lab. I was going to write HOW-TO on this one but then I came across Prajwal Desai’s blog. He has gone through the exact same Disk space issue I had. He wrote this nice Post on his Blog. Link is below. Please make sure you follow all Steps caqrefully and you have a backup of your SCCM/DB etc.
