Retrieve Server Uptime

Uses the WMI to pull system uptime with WMI timeouts, it will useful when remote WMI not responding.

I have used it for a few hundred servers and it works fine. The initial test-connection uses only 1 ping, so that it can go through a large list of servers very easily. 

Your ratings are most welcome, Which helps me to improve :)
