    Running Windows Server 2003 SP1. Running about 10 small public web sites on
    it. This is a single-server pointing to itself for DNS and running Active
    Directory. The AD zone is standard primary with "Secure and Non-secure"
    updates set to 'Yes'. All other zones (for the 10 small public web sites)
    have dynamic updates turned "off". None of those have name servers pointing
    to my ISP. They do however use the Notify feature to transfer to them a
    secondary zone. In DNS, under Forwarders, are the two IP addresses for my
    ISP's DNS server in question. They were also entered into the properties of
    the Default Virtual SMTP Server so that Exchange running on this box could
    do reverse lookups on the domains of incoming mail but I have removed those.
    The event ID error below basically indicates my server cannot communicate
    with my ISP server. I can understand that problems sometimes happens, as my
    ISP is hosting my secondary zones for the 10 small public web sites. But
    why is the server trying to communicate with it using DCOM? I would assume
    it would only try to communicate with it using standard tcp over port 53
    (zone transfer). To me that's just plain weird. I have been over every
    square inch of this server. DCdiag results also keep telling me I'm using
    the two ISP's DNS servers mentioned but I cannot see how/where I am doing
    that anywhere within the GUI. The Preferred and Alternate DNS servers for
    this server points to itself under network properties.

    Event Type: Error

    DCOM was unable to communicate with the computer <ISP DNS> using any of the
    configured protocols.
