:: ** IMPORTANT **
:: 1) Create a Sysmon folder with the SYSVOL share on your domain controller
:: 2) Download Sysmon from Microsoft and place both sysmon.exe and sysmon64.exe in
::    newly created Sysmon folder
:: 3) Download a sample sysmon config from SwiftOnSecurity, rename the file to
::    sysmonConfig.xml and place it within the Sysmon folder
:: 4) Enter the appropriate values for your DC and FQDN below.
:: 5) Create a GPO that will launch this batch file on startup.
:: 6) Apply the GPO to your specified OUs. 
::
:: Note: It is recommended that the Sysmon binaries and the Sysmon config file
:: be placed in the sysvol folder on the Domain Controller. The goal
:: being that the computers can read from the folder, but no one except for
:: domain admins have the ability to write to the folder hosting the files. 
:: Otherwise this will be a great way for attackers to escalate privs 
:: in the domain. You have been warned. 

:: Enter the full name of the domain controller, and FQDN for the domain. 
:: Be EXTEREMLY careful of spaces!! 
:: Example: DC=dc.corp.local
:: Example: FQDN=corp.local
