At first I always assumed this was the host applying updates or doing some maintenance. But after contacting the company, they assure me I would have received prior notice before any such event.
In finding the cause of the restarts, I really am not sure what I should be looking for.
They are seemingly random, sometimes 3-4 times a week, sometimes more or less.
Here's all the security log says. What's happening is I am logged in via RDP but I've been away for some hours and the server should be locked, when suddenly...

The server runs a webapp using IIS 6 and SQL Server 2008 R2 Standard. We're ready to get out of our beta, but this is really a big problem.
It was doing this since we were doing internal alpha testing (only allowing IIS to serve our IPs).
Thanks for any advice.
