    HI!

    What are the default open ports on XP Home? Why does XP sometimes open UDP 1029 (Openports says Explorer.exe is listening on that port)?

    Hey Porthound

    Depending on Windows configurations, Explorer.exe can be reason for listening ports.

    For instance: Is Active Desktop Disabled?

    In anycase you should do Scans using properly configured&updated Anti-Virus, Anti-Trojan and Anti-Spyware Systems...

    Hi Phantom,

    yes, Active Dekstop is disabled, I don't need it. I've scanned with Kaspersky AV and I'm also pretty sure I don't have any spyware on the machine. I've never seen Explorer.exe listening on 1029 before on this machine, so that's why I asked.

    Hey Porthound

    I think this is simply that of Internet Explorer, use TCPView on re-boot and then launch Internet Explorer. ;)

    Hi PortHound,

    it can be the DNS cache service under XP which takes a free port upper 1024 at first DNS request and keep it for all the session, unlike windows 2000 or each DNS request is assigned to a different socket.
    This behaviour can be disabled but it is not a danger.

    regards,

    gkweb.

    When reproducing the anomaly with Explorer.exe, I noticed it only happens with Internet Explorer and I don’t have DNS Client Service Enabled. ;)

    With XP Home you may find that port 5000 (Unplug&Play)is open by default.
    A scan at Shields Up! should tell you if it is open.
    There is a small,free utility available at that site which can open or close the port for you.It's called "Unplug&Pray".
    Unplug&Pray is available at the link below.

    As PhantOM stated:

    explore exe= UDP datagram

    WTH is a UDP datagram? :D

    I don't use IE, but the Opera browser... The UPNP service I've disabled. Strange stuff.

    UDP (User Datagram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol
