    "SMTP could not connect to any DNS server. Either none
    are configured, or all are down."
    I get this error on my event logs and I am having issues
    sending and receiving emails. I send some but the emails
    never get there. I check the knowledge base and there is
    nothing about this event id. The sites that due know
    want me to pay...help!

    I assume the DNS servers in question belong to your ISP. I get those
    sometimes myself. Usually, it is a transient event. In your case, they may
    have changed the IP address on one or more of their DNS servers, and would
    cause this error since it's hard-coded into the properties of the Virtual
    SMTP server (are you running Exchange?)

    Yes, I am on Exchange 2003 that is running on SBS 2003.
    We just cut over to a T! with static IP's for remote
    access but all of the workstations are also on a 10.10.
    subnet. If that helps any.

    You haven't told me if the DNS servers the event log is complaining about in
    questions are in fact running.

    Well, my SBS 2003 is running DNS but I also have two
    other DNS servers that I use from my ISP. Those ar
    running because I can ping them.

    Let's back up.

    All your internal clients point to your internal DNS server for resolution?
    Your DNS server has your ISP's DNS servers set as it's Forwarders?
    You also have your ISP's DNS servers set in ESM under the Default Virtual
    SMTP server properties > Delivery tab > Advanced?
