If it's not that, make sure that the service is running under the SYSTEM account and not a user account.

Turn off the web server piece or stop the recording service & install some other prgram that will let you configure the port like a ftp or telnet server. Configure that server to use 7647. Then try to connect to the machine using the appropriate client configured to use that same port.

On second thought, I just wrote a small Java app that will let you test your connection to a machine & port. If I can figure out how to attach the class file I will attach it to this. Otherwise, here is the source that you can compile yourself:

Code:

import java.io.IOException;
import java.net.ConnectException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.logging.Logger;

public class CheckPort
{
//  Set the logger on for CheckPort to see debug messages
//  See .\lib\logging.properties in your Java installation for more info
    private static Logger logger = Logger.getLogger("CheckPort");

    public static boolean inUse(String sHost, String sPort) throws UnknownHostException, IOException
    {
        logger.entering("CheckPort", "inUse");
        String altHost = "";
        try
        {
            logger.finer("sPort = " + sPort );
            int nPort = 0;
            if ((sPort != null) && !sPort.equals("") && !sPort.equals("null"))
            {
                nPort = Integer.parseInt(sPort);
            }
            else
            {
                throw new IOException();
            }
            InetAddress iHost = InetAddress.getByName(sHost);
            altHost = iHost.getHostAddress();
            if (altHost.equals(sHost))
            {
                altHost = iHost.getHostName();
            }
            logger.finer("altHost = " + altHost);
            
            Socket socket = new Socket(iHost, nPort);
            logger.fine("Created socket");
            
            int localPort = socket.getLocalPort();
            if (localPort != -1)
            {
                logger.finer("socket is connected");
                System.out.println("Connected to " + sHost + " (" + altHost + ") at port: " + sPort);
                return true;
            }
            logger.finer("socket is not connected");
            System.out.println("Could not connect to " + sHost + " (" + altHost + ") at port: " + sPort);
            return false;
        } catch (ConnectException e)
        {
            logger.finer("not in use");
            System.out.println("Could not connect to " + sHost + " (" + altHost + ") at port: " + sPort);
            return false;
        } catch (UnknownHostException e)
        {
            logger.finer("UnknownHostException");
            throw new UnknownHostException();
        } catch (IOException e)
        {
            logger.finer("IOException");
            throw new IOException();
        }
    }
    
    public static void main (String[] args)
    {
        if (args.length != 2)
        {
            System.out.println("Invalid number of arguments\nFirst argument is host and second argument is port");
            System.exit(1);
        }
        try {
            inUse(args[0], args[1]);
        } catch (UnknownHostException e) {
            System.out.println("Unknown host (" + args[0] + ")");
        } catch (IOException e) {
            System.out.println("IO Error");
        }
    }
}

To run it, place the classfile in a directory on the client machine. In a Dos prompt, switch to that directory & run this:
java CheckPort {yourHost} 7647
where {yourHost} is replaced by your host name or IP address.

For example:
java CheckPort pvr-vista 7647
or
java CheckPort 192.168.1.39 7647


I just wrote & tested this, so if anyone wants to try it out & let me know of any problems or changes that are needed, that would be great.

Now you can optionally pass in a URL instead of the host & port. It will find the host & port in the URL and use those values. For standard schemes like http, ftp, mms, https, etc., it will use the standard port number if one is not found in the URL. See the code below for the list of what I am using. I even support ignoring the username and password in the URL when specified with the @.

Examples:

java CheckPort http://dvr-vista:7647/gbpvr/Login.aspx
Can you connect to your EWA?

java CheckPort http://forums.nextpvr.com/showthread.php?t=36374
Can you connect to the GBPVR forums?

java CheckPort telnet://root@192.168.2.102
Can you connect to your mvp running mvpmc?

Maybe someday I'll rewrite this as a Windows app with a user interface.
