Tech-Archive recommends: Fix windows errors by optimizing your registry



dave,

let me recap, i unplugged the cat5 from comcast router plugged it into my
laptop-server / configured my laptop to a set Ip address just changing the 61
to a 66 perferred DNS was my server Ip address and default gateway was the
router address 10.1.X.X. did a telnet check three times and did not get a
response.

Exchange sounds like to me is not configured right any idea's thanks for
your help[

OK, you've pretty much ruled out Exchange configuration. I'm guessing that
if you configured it with the CEICW you don't have some bizarre issue like
Exchange not listening on the Internet NIC.

What I would do at this point is to configure your laptop or a spare machine
with an IP in the same range as your external NIC. Pop out the cable from
the Comcast router and plug it into that machine, and do the telnet test
again. If you get the same 220 response you got from within the LAN,
that'll confirm 100% that the problem is on the Comcast side.

You can test the connection from within the LAN, but if you have two
NICs,
you'll be testing the internal interface while SMTP is blocked at the
external interface. It's still blocked, by the way. If you ran the
CEICW,
I'm thinking that leaves the NAT device blocking port 25.

To test from within your network, on an XP desktop, open a command prompt
and type:

telnet <enter>
set localecho <enter>
open x.x.x.x 25 <enter> replacing the x's with your SBS internal IP

You should get a response starting with "220 mail.newhomes2day.com" plus
some other information.

From an external XP machine, you'd do the same thing but substituting the
public IP. All the telnet stuff is described in detail in the KB I
posted
in the original thread.

Please describe your network configuration. One NIC or two? Do you have
the LAN side of the Comcast router plugged directly into the Internet NIC
of
your SBS?

D,
#1 nat device on the comcast router,#2 re-ran CEICE

test now on dnsreport / logging in to comcast router about nat..

firewall on server how would i test to make sure port 25 is open from
internal network

Something is blocking connection attempts at your server. Do you have
an
external firewall or NAT device that needs port 25 opened inbound? If
you're absolutely sure it's not an external device that's blocking the
connection attempt, re-run the CEICW. For any page not relating to
the
immediate topic, just click the "don't change" option.

This doesn't relate to your internal domain name, which can be
anything.
Exchange is separate from that.

See my previous post on testing your server from an external PC using
telnet. You may not have to do this since you can see what's
happening
right in dnsreport, but that's the actual way one would test smtp
connectivity. But telnet to port 25 is the correct way of
troubleshooting
smtp connectivity.

FYI regarding your DNS, yesterday in the other thread when Cris Hanna
said
he saw one thing, and kj said he saw another, I saw both. First what
Cris
saw, then what kj saw. It looks to be fixed now, but your server is
still
rejecting connection attempts. See the text below, which I'm pasting
in
directly from a dnsreport.com check of newhomes2day.com that I just
ran.

ERROR: I could not complete a connection to any of your mailservers!

newhomes2day.com: The mailserver terminated the connection before the
transaction was complete (state 1). This is not RFC compliant, and
therefore
either due to an error, or it may be the result of a non-RFC-compliant
mailserver or non-RFC-compliant anti-spam program.
