Uptime (Powershell)

Generate HTML file with uptime of servers.

This script will generate an uptime File called uptime.html in the folder c:housekeeping

This script is orginally created by Ed Wilson of Microsoft. I adjusted it so that the date and time stamp is added to the file. This way you can see the history if you schedule is script on a regular bases. You will be able to see if reboots have occured.
