Dashboard Exchange-Integration - Windows Server 2012 R2 Essentials

Hello (at) all,

i try to integrate a Exchange 2013 Server. Essentials and Standard Server are both virtualized via Hyper-V 2012. Everytime I try to integrate it gives me an error that no Exchange Server could be found. Exchange works by the way. The Essentials Server is the only domain controller (learned that one the hard way...) See the log below:

I know that the OPEIntegration works via LDAP. If I search the Exchange-Server via the following script I find it without any problems.

Function Get-ExchangeServerInSite {
    $ADSite = [System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]
    $siteDN = $ADSite::GetComputerSite().GetDirectoryEntry().distinguishedName
    $configNC=([ADSI]"LDAP://RootDse").configurationNamingContext
    $search = new-object DirectoryServices.DirectorySearcher([ADSI]"LDAP://$configNC")
    $objectClass = "objectClass=msExchExchangeServer"
    $site = "msExchServerSite=$siteDN"
    $search.Filter = "(&($objectClass)($site))"
    $search.PageSize=1000
    [void] $search.PropertiesToLoad.Add("name")
    [void] $search.PropertiesToLoad.Add("msexchcurrentserverroles")
    [void] $search.PropertiesToLoad.Add("networkaddress")
    $search.FindAll() | %{
        New-Object PSObject -Property @{
            Name = $_.Properties.name[0]
            FQDN = $_.Properties.networkaddress |
                %{if ($_ -match "ncacn_ip_tcp") {$_.split(":")[1]}}
            Roles = $_.Properties.msexchcurrentserverroles[0]
        }
    }
}

    $role = @{
    2  = "MB"
    4  = "CAS"
    16 = "UM"
    32 = "HT"
    64 = "ET"
}


   foreach ($server in Get-ExchangeServerinSite) {
  $roles = ($role.keys | ?{$_ -band $server.roles} | %{$role.Get_Item($_)}) -join ", "
  $server | select Name, @{n="Roles";e={$roles}},FQDN
}

Any help would be greatly appreciated. Sorry for the poor english...
