Yep, all of them. I open it up, and it's like a fresh install on a new computer. No triggers that I can think of. I have used Server Admin all the way back to the Jaguar days and never had this problem. This is on my laptop, of course, whose mobility may contribute to this, but still what a pain! I will try the 10.6.2 tools.
I experience this issue on multiple machines, it is not isolated to any particular laptop that I access the servers from.
The one thing I have tracked down is that it happens when I “close” the server admin window as opposed to (or prior to) quitting server admin. Quitting server admin (with the window open) results in all of my servers remaining.
Check on yours to see if you experience similar behavior but that’s what I have isolated it to on my end.
