Good Morning,
Has anyone updated/modified the DHCP plugin for xymon,
Currently we are using the following ext script to monitor our DHCP servers on 2008 however we seem to be running into issues on 2012
Thanks in advance.

' BigBrother External Script for testing to see if Dhcp is up and responding on Window 2003 and above
' Gives Scope details running on the server specified With Active/Excluded and Available leases
' Installation
' 1) Modify the vairables below to match your system.
' 2) Add the script to your externals list in bbntcfg on the DHCP Server.
' so that it runs at least every 6500 seconds
' 3) Make sure you set the Saved Logs Location to %BBHOME%\ext
