Recently I have found that most of the clients are not showing up in SCCM "All Systems" collection. When I "Initiate Actions" from the Configuration Manager, client will appear again.

Anyone have an idea or can help.

Thanks - Ahmad

Hi,

Just to clarify. Are the clients disappearing from the console and then after you initiate actions they reappear. What actions are you initiating?

Hi Kent,

The clients are disappearing from SCCM server "All Systems" collection then they reappear after I initiate all the actions from the clients "Configuration Manager " in control Panel.

It sounds like clients are being deleted from the console/database. Do you have a tool installed that markes clients as inactive and then delete them?

See if the heart beat is set to like 1 or 2 days, also check to see if you have Uninstall Client flag turned on in your Task Maint.

What is happening is the server sees it as "dead" machine and removes it. When you initiate and action then SCCM gets a response from the client and sees it as active.

Gentlemen,

Thank you so much. The problem has been fixed by enabling the heartbeat discovery.
