    Ah! I saw this right after I sent my other post,...check it out....(hehe).

    It is seeing the "dots" in the IP# and treating it as a FQDN (treats the
    numbers as if they were letters). It then trys to process it that way and
    creates a mess.

    Keep in mind that *all* FQDNs are *assumed* to be out on the Internet until
    after they are resolved to an IP#,...so they always are proccessed by the
    proxying service. Once they are resolved and determined to be on the Private
    side of the LAN the "proxying services" bail out and let it transit to the
    destination directly. If it improperly interprets the IP# in the URL to be a
    FQDN instead,...well the problem becomes obvious.

    MS Exchange and the IIS SMTP Service will also do this and require that a
    raw IP# be enclosed in [ ] such as, [192.168.1.3] to indicate that they
    are simply a raw IP# and not a FQDN. But I doubt that would work with ISA if
    you did that in the browser's address bar.

    Unfortunately, I'm not sure what causes it and I have no idea where the
    problem is happening either to even know what to blame.
