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:tempserveruptimev2.vbs)
• open a command prompt
• go to “c:temp”
• give “cscript serveruptimev2.vbs” (without quotes) and enter

The script:

' Description : script to enumerate the system uptime of all servers in Active Directory V2

In large Active Directory environments it is useful to know the uptime of each server (for patches, etc.).
This script lists all servers in Active Directory, checks if they are alive and if so check their uptime.
It can be run as a scheduled task (for example every day or week).

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:tempserveruptime.vbs)
• open a command prompt
• go to “c:temp”
• give “cscript serveruptime.vbs” (without quotes) and enter

The script:

' Name : serveruptime.vbs
' Description : script to monitor all servers in Active Directory

strDNSDomain = objRootDSE.Get("defaultNamingContext")
strBase = "<LDAP://" & strDNSDomain & ">"
strFilter = "(&(objectCategory=computer)(operatingSystem=*server*))"
strAttributes = "name"

strQuery = strBase & ";" & strFilter & ";" & strAttributes & ";subtree"
