WMI kald fra C# til anden maskine

Hej alle

Jeg skal hive data fra en anden maskine, men uanset hvad jeg gør får jeg info på localhost. Er der nogen der kan fortælle mig hvad der er forkert i nedenstående, siden jeg ikke får data på "TestMaskine" (men på localhost).

    public string Testing()
    {
        long mb = 1024 * 1024; //megabyte

        //Connection credentials to the remote computer - not needed if the logged in account has access
        ConnectionOptions oConn = new ConnectionOptions();

        //oConn.Username = "username";
        //oConn.Password = "password";

        System.Management.ManagementScope oMs = new System.Management.ManagementScope(@"\\" + "TestMaskine", oConn);

        //get fixed disk stats
        System.Management.ObjectQuery oQuery = new System.Management.ObjectQuery("SELECT FreeSpace, Size, Name FROM Win32_LogicalDisk WHERE DriveType = 3");
        ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery);
        ManagementObjectCollection oReturnCollection = oSearcher.Get();

        //variables
        string name = "";
        double fs = 0;
        double us = 0;
        double tot = 0;
        double up = 0;
        double fp = 0;

        //select objects
        foreach (ManagementObject oReturn in oReturnCollection)
        {
            // Disk name
            name = oReturn["Name"].ToString();

            //Free space in MB
            fs = Convert.ToInt64(oReturn["FreeSpace"]) / mb;

            //Used space in MB
            us = (Convert.ToInt64(oReturn["Size"]) - Convert.ToInt64(oReturn["FreeSpace"])) / mb;

            //Total space in MB
            tot = Convert.ToInt64(oReturn["Size"]) / mb;

            //used percentage
            up = us / tot * 100;

            //free percentage
            fp = fs / tot * 100;
        }

        string extraInfo = ". Should be around 48 GB (not 8,26 GB, that's localhost).";
        switch (1)
        {
            case 1:
                return "Free space in GB: " + (fs / 1024) + extraInfo;
                break;

            case 2:
                return "Used space in GB: " + (us / 1024) + extraInfo;
                break;

            case 3:
                return "Total space in MB: " + tot.ToString() + extraInfo;
                break;

            case 4:
                return "Used percentage: " + up.ToString() + extraInfo;
                break;

            default:
                return "Free percentage: " + fp.ToString() + extraInfo;
                break;

        }
