Mini Restarts When Shut Down

My Mini is a basic 2Ghz dual processor Intel model running 10.6.4. I run it almost exclusively via Desktop Sharing from a Macbook, but it has a keyboard and mouse connected. When I shut it down, about half the time, it starts up again in a few seconds. I've been very careful to select "shut down", not "restart". I've turned off the preference that causes it to "listen" for network activity. I can't see any particular set of conditions that exist when this happens that don't exist when it doesn't.

Does anyone have any knowledge of this they can share?

iMac 27" i7, Macbook Core 2 Duo, 2Ghz, 2G RAM, Dual 2Ghz PCI G5, 2G RAM 10.5.8, Mac OS X (10.6.4), MOTU 828 Mk 3, 2408 Mk 2, and Micro Lite. DP 7.1, Logic 8.02, UAD-1

Just want to chime in and say I'm also having this problem. It seems to happen quite randomly, I haven't seen any pattern to it yet. I've ensured "restart after power failure" is off. I do have an automatic startup time set, which works correctly, but that shouldn't normally cause it to turn on immediately after shutting down.

Other than a keyboard or mouse, do any of you have other devices connected to it? I am having the same problem from time to time. I brought my mini into a local mac authorized service place, and they told me the mini was fine and that my device (a drobo) may be the cause of the problem.

I wrote an email to CNETs Macfixit guy and got a couple of options to try

Reset the PMU

Reset the SMC

Reset the PRAM

I reset the PMU and the SMC and it worked for a while, then did the same thing again about a week down the road. Hope this helps someone.
