I don't know about sam30, but for me
How many client having same issue?
50% - 70% out of +-7000 clients
What OS version available?
WinXP, Win 7, Win2003, Win2008
What Sep version avaialble there.?
v11 RU5, v11 RU6 MP3, v11 RU7 MP2
So pretty much across the board.
One thing we have noticed, is that that number decreases as the day progresses. It would seem that as the clients report in initially, Tamper Protection is off and switches on shortly after, but is only reporting correctly after the next heartbeat.
