How to determine firewall status of a remote machine?

I used following codes,
1)

try
{
   TcpClient tcp = new TcpClient();
    tcp.Connect("RemoteIP", Convert.ToInt16(135));
    Console.WriteLine("online");
}
catch (Exception ex)
{
    Console.WriteLine("offline");
    Console.WriteLine(ex.Message);
}

2)

Type NetFwMgrType = Type.GetTypeFromProgID("HNetCfg.FwMgr", REMOTEIP, false);
INetFwMgr mgr = (INetFwMgr)Activator.CreateInstance(NetFwMgrType);
Firewallenabled = mgr.LocalPolicy.CurrentProfile.FirewallEnabled;
return Firewallenabled;

----------------------------------------------------------------------------


* The first one will always connects to the port 135 if though Firewall is ON/OFF
* The Second one will determine the status correctly but,it requires user to be in the administrator group of remote machines and My Machine is of 64 bit and remote machine is of 32 bit which throws COM ERROR





Any other work around or Suggestions are welcomed,
