+   <#
+      .SYNOPSIS
+      Set all Active Directory related commands to use a special kind of server
+
+      .DESCRIPTION
+      By default the Active Directory related commands search for a DC. By default I want to make
+      use of the closest one. When I make BULK operations, I would like to use the Server with
+      the PDC role. This becomes handy often!
+
+      .PARAMETER pdc
+      Use the Active Directory Server who holds the PDC role.
+
+      .EXAMPLE
+      # Use the closest Server
+      PS> Set-ADServerUsage
+
+      .EXAMPLE
+      # Use the Server with the PDC role
+      PS> Set-ADServerUsage -pdc
+
+      .EXAMPLE
+      # When it comes to scripts that do bulk operations, especially bulk loads and manipulation,
+      # I use the following within the Script:
+      if (Get-Command Set-ADServerUsage -ErrorAction SilentlyContinue)
+      {
+      Set-ADServerUsage -pdc
+      }
+
+      .NOTES
+      I use this helper function in my PROFILE. Therefore, some things a bit special.
+      Who want's an error message every time a window opens under normal circumstances?

+   param
+   (
+      [Parameter(ValueFromPipeline,
+         ValueFromPipelineByPropertyName,
+         Position = 1)]
+      [switch]
+      $pdc

+   {

+      <#
+         The following would do the trick:
+         #requires -Modules ActiveDirectory
+         But I don't want any error messages, so I decided to use this old-school way to figure
+         out if we are capable do what I want.

+            # Use the PDC instead
+            $dc = ((Get-ADDomain -ErrorAction $SC -WarningAction $SC).PDCEmulator)
+         }
+         else
+         {
+            # Use the closest DC
+            $dc = (Get-ADDomainController -Discover -NextClosestSite -ErrorAction $SC -WarningAction $SC)
+         }
+
+         # Skip everything if we do NOT have the proper information.
+         <#
+            Under normal circumstances this is pretty useless, but I use some virtual machines that have the RSAT tools installed, but they are not domain joined.
+            The fore I make this check. If all the systems that have the RSAT installed are domain joined, this test is obsolete.
