Are you able to change the port number in Windows Home Server 2011 from 4125 to another port? RRS feed

  • Question

  •  I only ask this because my ISP Knology is blocking that port and not admitting to it. I had to almost force them to open 80 and 443. Now they are saying that in my contract i cant have a server on there internet connection. Please Help!!! All i want is a working server for me to watch my recorded TV from my Windows Media Center Win7 on my Windows Phone 7.5 when I am gone from the house.

  • SBS 2003 and WHS v1 needed port 4125 for Remote Web Workplace (RWW). Later versions no longer used port 4125 only 443 for secure access. You must have some other port conflict.

    When I do the Remote Web Access Wizard it tells me a port is either being used or is blocked. I am in the DMZ on my router so my router cant be blocking any ports. Are the required ports for Remote Web Access 80,443, and 4125? That is what I found out online.

  • Run ShieldsUp at www.grc.com - that will show which ports are actually open. It will not tell you if it's a router or ISP problem.

  • Windows Home Server 2011 doesn't make use of port 4125. The windows phone app doesn't use SSL for streaming, either, but I believe others have had problems with .wtv files (the file that Media Center creates when you record television).

  • it does not allow remote web access unless i open ports 80,443, and 4125. I need those open for me to share with myself over the internet.

  • As Ken said port 4125 is not needed in WHS 2011. Why do you think it is? It was needed in the original WHS.

  • when i go online to canyouseeme.org when I do 443 port it works but Windows Home Server 2011 gives me that error. I have nothing on my network or on my computer that uses 443. Also what does port 443 specifically do?

  • 443 is for a secure connection (https)

    Try changing your settings in IIS of the listening port:

  • Is there any way that my ISP is blocking the ports I need without telling me? They have lied before to me about throttling my connection. We caught them and got 3 months free service. We pay for 15Mbps down and 2Mbps up and they throttled it to 3Mbps down and 500Kbps up.

  • I did the scan. I am in the DMZ on my router so it is not blocking anything. If you see the picture all that blue means it is blocked. Green means stealth and red means open. As you can see all of them should be open. But they are not even though i am in the DMZ. What does this mean.

  •  What does this mean.

    That a firewall, somewhere, is blocking those ports. Shields Up explains very clearly what each of the three possible results means: Open means that there's something listening on that port that accepted a connection attempt, closed means that something responded and denied a connection attempt, and stealth means there was no response at all. Most likely, in your case, your ISP is blocking all ports that are showing as closed or stealth. However, even if they aren't, most ports would show as closed or stealth anyway, since Windows has a firewall built in.

    I'll warn you that, since your ISP has stated that running a server on your internet connection is against the terms of service you've already agreed to, you're risking quite a bit by pursuing this. Depending on the subscriber agreement you're subject to, they could potentially terminate your internet connection with no warning, start charging you a higher rate (for a business class of service that allows servers), or even backdate additional charges to when you first requested that ports 80 and 443 be opened.

  • Port 443 is Open, so you should be able to gain secure (https://) access to your Server. But heed the warning given by Ken above.
