Re: network topology

Well now I feel like an idiot and much better all at the same time.
I called my ISP, went through a few tests, repowered the modem, hubs and
router and voila, all is well. My sincer thanks to Claus for your persistance
in trying to resolve this issue.

Something doesn't sound right. The normal setup would be that your cable
modem has a WAN and a LAN side. The WAN side has the static IP from your
ISP. The LAN IP is normally something like 192.168.0.1. You would configure
your SBS WAN to something like
IP 192.168.0.2
GW 192.168.0.1
DNS 192.168.16.2

What is your ISP? What type of cablemodem do you have?

Hello again Claus, really appreciate your help with this.
Local Area Connection is now working fine, thanks! I'm able to login and
open companyweb from client computer.

There is nothing but a hub between the server and the ISP's cable modem.
Even if I bypass the hub and go direct to the modem, no change.
All computers on the wireless router network are working fine
I changed IP to .225 on SBS and still no result. Back to .214 now.

Displayed from CEICW wizard:
DNS Servers:
PReferred: 64.59.144.18 (assigned from ISP)
Alternative: 64.59.144.19 (assigned from ISP)

Static IPs from ISP:
24.82.160.214 (SBS server)
24.82.160.225 (router off domain)
Assigned GW: 24.82.160.1

What sits between the internet and your SBS?

As long as the ISP DNS servers are not in the 24.82.160.1 to
24.82.163.254
range you should still get name resolution but you will not get to any
server in that IP range.

Depending on where you are located, I would try some other DNS servers.
But
first test the ping to 4.2.2.1. If you don't get a response, there is
something wrong with your internet access.

If that's the case I would plug a laptop into your ISP connection and
configure it with the same IP as your server (unplug the server) and test
if
you get out with the laptop.

Hello Claus, thanks again for your reply.

That GW was assigned by my ISP
IP assigned by ISP is 24.82.160.214
Sorry I don't have the DNS IP's here (I'm at home now) but will post
them
here tomorrow morning.

I tried pinging a couple of different sites (google, microsoft) with no
reply.
No packets are being received on the extenal NIC
Companyweb opens fine.
I'll try 4.2.2.1 tomorrow when (I'm back in the office)
Any ideas in the meantime would be greatly appreciated.

Your internal NIC looks fine. Your external is very unusual. Are you
sure
that it is correct?
Where does your GW 24.82.160.1 sit and what are the DNS IP address
that
your
ISP gave you?
The reason why I'm asking this is if the GW is at your office any
traffic
for 24.82.160.1 up to 24.82.163.255 will not leave your office because
it
is
considered within the local subnet.

Did you test to ping from the server to say www.google.com? What is
the
response? Did you test to ping known public addresses? Give 4.2.2.1 a
try
and see if you get a response.

OK but SBS still cannot connect to the internet :(


"Claus" wrote:

No, that is correct. The only DNS that should show up on the WAN
and
the
LAN
NIC of the SBS is the SBS DNS which is the IP of the LAN NIC.
Your
ISP
DNS
servers are entered under the Forwarders tab on you DNS.

Yes, I did it with the wizard, then ran CEICW afterwards.
Interesting note: the CEICW always changes the WAN (internet)
DNS
to
the
same one I assigned locally (192.168.16.2). I guess this means
I've
done
something wrong with the Local Area Connection?

TIA
Robert

If you changed the LAN IP did you do that with the wizard or
manually?
Did
you run the CEICW after the changes?

OK I've done that. Now the server is unable to connect to
the
internet
(even
though the network connection indicates the server is
connected).
The
local
area connection indicates it is connected as well but no
computers
are
visible. FYI I've also installed ISA.

while its not absolutely required...it is more secure to
split
them
up
So get a second router to be used by the SBS server and
configure
the
External IP as it is now
Configure the Internal IP as 192.168.16.1, Turn DHCP off
on
the
router
Start the DHCP Service on SBS and set it to automatic
Then on the SBS server, Server Management Console, Click
on
Internet
And
Email
then run the Change Server IP Wizard, make it 192.168.16.2
When thats complete, Re-run the Connect to Emailand
Internet
Connection
Wizard (CEICW)

Your two workstations will now get their addresses from
the
SBS
server,
not the router and all will be well!

I recently set up sbs and I'm now wondering if I used
the
right
network
topology. We have 2 workstations on the domain, both
mobile
users.
We
also
have a wireless router for use by a workstation not on
the
domain,
and
used
as the DHCP server (sbs assigned a reserved ip).

We have 2 static IP addresses from our ISP. Currently I
have
the
sbs
behind
the router, with a one NIC config. I'm thinking a
possible
alternative
which
I hope someone can advise whether it is worth doing this
or
not:

Separate the wireless network from the domain using the
spare
static
IP
and
a hub.
Add a NIC to the sbs server and a hub to connect the
clients
to
sbs.

Is it worth re-installing SBS (still possible if
.
