Alerts come through after Server taken out of maintenance mode

Hello

We are still using SCOM 2007 R2 (CU6)  :(

some times when we put a Server into Maintenance Mode e.g. > OpsMgr Console > Monitoring > Windows Server. The right click Maintenance Mode > Start  Maintenance Mode

we then do what ever e.g. patch server and reboot etc. when the Server comes backup and comes out of Maintenance Mode we get an alert to say "Heart beat failure" and "Server unreachable" e.g. the normal alerts you would expect if the Server was not in maintenance mode.

Does any one know they this happens? is there a fix?

Has Maintenance Mode been fixed in SCOM 2012 R2 ?

Thanks All
