        Are you getting an error message when you attempt to use telnet
on your Vista box or is the command timing out.
        
        To my knowledge, unless you elevate your rights on the Vista box
(right-click cmd.exe and select Run As Administrator) you can't use the
tool, assuming it has been installed.

        Internal box, my computer, which is Windows Vista, gateway is
set to the
        ISA server. I put it as the #1 rule, still no go. Nslookup works
fine
        and finds exchange.titusville.com, but of course that's a
different
        protocol.

        It would need to be before any deny rule that would prevent it
from
        being allowed.  You're telnetting to 25 from an internal box and
not the
        ISA box itself, right?  And the internal box either has the
firewall
        client installed or has the ISA box's internal IP set as it's
default
        gateway?
