We use SCCM 2012 to deploy our Windows 3.7 agents and for patching servers. Every so often,I come across a server that is no longer reporting into Inventory. When investigating, I notice the agent is no longer installed. Further investigation shows that SCCM removed it at the beginning of it's patching job. The Windows event log shows SCCM tried to install the agent (no idea why since it's already installed) and then failed, leaving no agent installed. The SCCM techs are unable to find any indication as to why this is happening. It happens on 1% - 2% of the servers (not the same servers every time), but with thousands of servers, that adds up.
Has anyone else experienced this issue?
