PowerShell InvokeGet the directory property cannot be found

We needed to retrieve the information in active directory concerning 'Terminal Services'. For this I've created the following function:

Function Get-ADTSProfile {
               [CmdletBinding()]
            Param(
                [Parameter(Mandatory=$true,Position=0)]
                [String] $DistinguishedName,
                [parameter(Mandatory=$true,Position=1)]
                [ValidateNotNullOrEmpty()]
                [ValidateSet('UserProfile','AllowLogon','HomeDirectory','HomeDrive')]
                [String]$Property
            )
            Begin {
                $User = [ADSI]"http://LDAP$DistinguishedName"
            }
            Process {
                Switch ($Property) {
                    'AllowLogon'    {if ($($User.psbase.InvokeGet('allowLogon')) -eq '1'){$True}else{$False}}
                    'HomeDirectory' {$User.psbase.InvokeGet('TerminalServicesHomeDirectory')}
                    'HomeDrive'     {$User.psbase.InvokeGet('TerminalServicesHomeDrive')}
                    'UserProfile'   {$User.psbase.InvokeGet('TerminalServicesProfilePath')}
                }   
            }
        }

Most of the time this works fine, however, with some users we have issues. An example of the error:

Get-ADTSProfile -DistinguishedName 'CN=test\, test (Den Bosch) NLD,OU=Users,OU=Disabled,OU=NLD,OU=EU,DC=grouphc,DC=net' -Property 'UserProfile'
Exception calling "InvokeGet" with "1" argument(s): "The directory property cannot be fo

I can't really figure out why it works on some and not on all..
