the Citrix Group Policy Management tools must be installed
.EXAMPLE
Get-CitrixRSOP -ComputerName "TargetPC01"
.EXAMPLE
Get-CitrixRSOP -ComputerName "TargetPC01" -Protocol DCOM
.PARAMETER ComputerName
The computer to retrieve the policies from
.PARAMETER Protocol
The protocol used to retrieve the WMI objects from the remote computer. Defaults to CIM, but
DCOM can be specified as well.
.PARAMETER SessionId
The user session ID to get user policies for. For XenDesktop this will always be 1 (the default).
