Setting AD logging

Now that we know what the options are we can look at switching them on.

function set-logsetting{             
[CmdletBinding(SupportsShouldProcess=$true)]             
param (             
[parameter(Position=0,            
   Mandatory=$true,            
   ValueFromPipeline=$true,             
   ValueFromPipelineByPropertyName=$true)]            
   [string]$computer,            
               
   [string]$setting,            
               
   [ValidateRange(0,5)]            
   [int]$level             
)             
BEGIN{            
 $HKLM = 2147483650

PROCESS{            
 if ($logtype.Values -notcontains $setting){            
   Throw "Incorrect setting - please use get-logsettingoptions"            
 }            
             
 $reg = [wmiclass]"\\$computer\root\default:StdRegprov"            
            
 $key = "SYSTEM\CurrentControlSet\Services\NTDS\Diagnostics"

The setting and level are input as parameters. The level can be checked as a range – the setting to log is checked against the hash table of logging types. The WMI SetDWord method is used to perform the change. A few of the ways the setting to use can be input are shown in the help examples.
