Powershell script to create user home directory and DFS namespace target

Creating a new users home directory and corresponding DFS namespace target. The script can also force all domain controllers to fully sync up in case you have multiple sites. Sync is enabled by default, however it can be disabled. This powershell script does require WinRM to be enabled for sync to work. You need to have setup the DFS namespace root path already.
