Active Directory and WMI: VBscript to enumerate the system uptime of all servers in Active Directory V2

The script for today is created for Paul.
It is an extension of the previous server uptime script.
The uptime is now formatted in: xx days, xx hours, xx minutes.

Follow the next steps to run the script (admin rights needed for the WMI connections):

• copy and paste the script in your favorite text editor
• save the script (for example c:\temp\serveruptimev2.vbs)
• open a command prompt
• go to “c:\temp”
• give “cscript serveruptimev2.vbs” (without quotes) and enter

The script:
