Re: ConnectComputer Problem

Not sure I understand the question. With a (2 NIC + router) network setup,
the external must be given an IP address in the same range as the LAN side
of the router. So, if your router LAN side uses 192.168.1.x, with the
router itself being 192.168.1.1, the SBS external NIC must be in that range
(something like 192.168.1.2 or higher).

Does this answer your question?

We have a couple of questions:

What range the static ip address of the external nic should be? Since we
are using the generic ip address of 192.168,16.2 on the internal. Should
the configuration be the same with the static ip address on the wins, dns,
and the default gateway?

Thanks for your patience,
Stephanie

With a workstation, you generally don't care if the dynamically assigned
NIC
IP address changes. However, you don't want server NICs to change their
IP
address. You are forwarding port traffic (443, 4125, 25, 3389, etc.)
from
your router's public side to the IP address of the external NIC on the
SBS
server. If that IP address changes, traffic will not continue to be
correctly routed. Therefore, you should use static IP addresses for all
server NICs.

Both DHCP services will run independent of each other.

You actually have 3 networks involved with a 2 NIC + router setup.

1) The Internet + the router's public (WAN) side
2) The router's private (LAN) side + the SBS server external NIC
3) The LAN side of the SBS server + its workstations. (This includes
the
SBS firewall, either ISA firewall if SBS Premium or Windows Basic
firewall
if SBS Standard, which is configured when you run CEICW).

Traffic from one network to another is isolated by the "firewalls"
(loosely
speaking) on the router and the SBS server. By default, the DHCP traffic
from the router's LAN side will be isolated from the DHCP traffic on the
SBS's LAN. This will allow any computers attached to Switch1 to get an
IP
address from the router, since these computers will be located in the
router
LAN (which is outside of the SBS LAN).

Our configuration is set up like the final set up you described.
You've
stated that
we need to give the server's external NIC a static IP address, correct?
We've been told
that it should be assigned by DHCP. Which way is correct? Will this
casue
a conflict with
two DHCP services running?

"Merv Porter [SBS-MVP]" wrote:

OK. Which "setup" are you referring to in my last post? (1) Your
current "physical setup", or (2) what I described as your "final
setup"?

Again, this would be my preferred (final) setup...


Internet
|
Broadband Modem
|
Router --- Switch1... (attached computers; 192.168.1.x IP addresses)
|
SBS server (external NIC; static IP address 192.168.1.2)
||
SBS Server (internal NIC; static IP address 192.168.16.2)
|
Switch2
| | | |
Workstations (will get IP addresses from the SBS server in the
192.168.16.x
range)


Make sure the external and internal NICs of the SBS server have static
IP
addresses assigned to them. (You don't want these IP addresses to
change).

Switch1 is connected to a free port on the router. As long as this
is
physically set up properly, the SBS server will then be isolated from
your
router and your (assigned computers) attached to Switch1. Switch2 is
connected only to the workstations and the internal NIC of the SBS
server
(not to the router). The SBS external NIC is attached to a free port
on
the
router.

So the router can run DHCP service for the (attached computers) and
the
SBS
server can run a separate DHCP service for the (workstations). All
you
should need to do is re-run CEICW, enable the firewall, select the
services
you want, complete the Web Server Certificate and finish CEICW. This
should
configure the SBS server with the DHCP service and all other required
services. Then reboot your workstations and they should pick up an IP
address from the SBS server's DHCP service.

You will also need to forward all ports for the selected services
(443,
1723, 4125, 25, etc.) to your SBS server's external NIC (192.168.1.2)
so
that remote traffic can be properly routed to your SBS server.

Again, just follow the diagram at:
http://www.smallbizserver.net/Default.aspx?tabid=266&articleType=ArticleView&articleId=74

Please let me know if this is still not clear.

The set up you suggested is how our system is configured. The IP
address
of
the servers internal NIC
has same IP as the workstations as described in the diagram. Can
you
explain how our
NIC cards IP addresses should be configured. We are still getting
"Can't
find server"
error message when we try to run Connectcomputer.

We tried to make the domain name of the client systems, the domain
of
the
server,
this seems to cause a problem.

I'm a little confused by your network configuration. I'm not sure
what
you
are trying to accomplish with the 2 switches. If I've interpreted
your
description correctly, both switches would be on the same network
segment
and would not be "remote" to the SBS server.

Is this your physical setup?


Internet
|
Broadband Modem
|
Router --- Switch1
|
Switch2 --- SBS Server (with single NIC in the SBS server)
| | | |
Workstations


SBS works best when it controls the DHCP service for the its
network.
If
you want to isolate the SBS network from Switch1, put a second NIC
in
the
SBS server, then let the SBS server handle DHCP for its network
segment
(the
workstations). (The router would then handle DHCP for any
computers
attached to Switch1). Set is up similar to this diagram:

http://www.smallbizserver.net/Default.aspx?tabid=266&articleType=ArticleView&articleId=74

Then re-run CEICW.

Your final setup would look like:

Internet
|
Broadband Modem
|
Router --- Switch1... (attached computers)
|
SBS server (external NIC)
||
SBS Server (internal NIC)
|
Switch2
| | | |
Workstations

Merv,

A gentleman (Greg) that I work for settng up the server posed the
following
questions, any help
would be greatly appreciation.

The first question would be what if I was trying to connect from
a
remote
location? The set up here is that we are using two switches.
The
broadband
modem plugs into the linksys router and the router connects the
internet
to
the two switches and provides the IP address to all the clients.
The
one
switch has internet access all the time, the second switch has
the
client
computers connecting to the server. All the nic on the clients
point
back
to
the server internal nic with a generic setting of 192.168.16.2.
the
clients
can get to the Network configeration page but no further. The
internet
connection is not stable on the switch connected by the server,
but
is
on
the
other switch. Is there something we missed, and can we use the
other
switch
to connect to the server remotely.

Domain Name... no, you don't have to register it if it is an
internal
domain
name (not one that you use to connect the server from a remote
location,
like http://mycompany.com)

Have you re-run CEICW and does it complete without error?

We're using the Linksys Wireless - G broadband router model
no.
WRT54G

No, we have not tried another IP address

The error message we're receiving is "Page Cannot Be
Displayed"
the
error
code at the
bottom reads "Cannot find server or DNS error"

Does the Domain Name need to be registered by the ISP
provider.

"Merv Porter [SBS-MVP]" wrote:

Well that's strange.

What make/model router do you have?

Have you tried another IP address other than 192.168.1.105
for
the
external
NIC?

What is the exact text of the error message that you are
getting?

Tried to change external NIC to a static I.P assignment
when
we
recieved
invalid/error subnet mask. I am not understanding why that
error
is
occuring
for subnet mask 255.255.255.0. Any Ideas why that is
occuring

Any ideas?

Only a couple of things to note...

It looks like you have a 2 NIC + router network setup.
The
external
NIC
should have a static IP address assigned to it (not a
dynamic
one
assigned
by the router's DHCP service). You don't want the
external
NIC
IP
to
change
at the whim of the router.

Re-run CEICW and specify the ISP's DNS nameserver's as
"forwarders"
