    I'm trying to connect my 360 to an MCE2005 PC running Norton's 2008 firewall
    product. I get to the point where I enter the 8-digit setup key and after 15
    seconds or so it errors out complaining about the firewall. I have added the
    following 6 programs to Norton's firewall config (Norton knew about all of
    them and automatically generated a set of firewall rules for each). Still
    same error. I then went back and changed the rules to allow FULL network
    access for all 6 programs: still same error. Finally, I disconnected my
    router from the Internet and then disabled Norton's firewall completely:
    Success!! I was able to connect and see the MCPC from the 360. However, as
    soon as I reenabled Norton, no joy. There must be some other program or
    setting that I am missing here.
    The six programs I have added firewall rules for are:

    Does anyone have a suggestion how to go about diagnosing this problem??
    Maybe Ethereal/WireShark??

    Thanx for the quick reply; I read through the 2 links you provided
    (actually I had used the 2nd one to come up with the 6-program list I
    originally posted), and couldn't see which programs I'm short?? Both of
    those lists show the same 6 that I have.

    Am I missing something ??

    OK, here's the answer in case some other poor slob finds himself in the same
    Norton Firewall settings are broken into 3 main categories:
    1. General Settings which apply to all access to the machine.
    2. Program Settings which apply to specific programs.
    (This is where I set up MCE program access according to Microsoft
    3. Trust Control which supposedly allows or disallows access to MS
    Shared folders and files.

    What I discovered was that even if I had ALL the firewall rules set up
    correctly for each of the Extender related programs, if the XBox is NOT added
    to the Trusted list (either by IP or MAC address), no traffic is allowed
    between the two devices. Once I added it, everything works as documented!

    Thanx for reading,

  6. Glad you got it working. Just for reference, the KB article I posted
    earlier lists the 8 programs that need inbound or outbound permissions in
    the firewall.

    Program/File Name Port Direction
    Ehshell.exe TCP5555 Incoming
    Ehshell.exe UDP 7777 Incoming
    Mcrdsvc.exe UDP3776 Incoming
    Svchost.exe UDP 1900 Incoming
    Svchost.exe TCP 3390 Incoming
    Mcxnettw.exe Random Outgoing
    Mcrmgr.exe TCP3932 Outgoing
    Ehexthost.exe Random Outgoing

    Thanx again for your responses. There are actually only 6 programs in the
    list in that first KB article you referenced (Ehshell and Svchost each appear
    twice for separate TCP and UDP port entries). This matches the entries in
    the other Microsoft article, which turned out to be sufficient once I added
    the XBox to Norton Trusted list.
