We spent about 15 hours working to reinstall on the same equipment with no
luck, so we put our old system back together and tried with it. No
problem
at all (at least everything appears to be working). It must have been the
motherboard or CPU that was causing the problems, because it took only a
couple of hours when we started working with the previous equipment, and
everything is fine.

Thanks for the help!

Hi Rick,

Thanks for your update. I appreciate your time and efforts to the issue.

Can I conform to your network topology as follows:
->SBS server (2 NIC, with 4 public IP)
Internet -> hub - {
-> Router (with 1 public IP) ->
{internal
network}

Is it true?

If you setup network like above, the computers in internal network
access
the SBS server box is the same as the internet computers although they
are
in the same physical location. All requests from internal network to SBS
server is transferred in internet since they have different public IP.
You
need open port 25, 80, 443, 444, 4125, 3389 in the Router, so that these
traffic can be allowed between SBS server box and computers in 'internal
network'.

However it is not recommended that you setup SBS network like this. I do
not understand that why you separate them using router. Can you describe
me
more detail about what you want to achieve

The following scenarios are recommended:

One network adapter:
-> SBS server
Internet -> Router - {
-> {internal workstations}

Two network adapters:

Internet -> Router -> SBS server -> {internal workstations}

Or
Internet -> Router -> SBS server ->hub -> {internal workstations}

You can setup network in two network adapters scenario for more security.

I suggest that carefully take a look the following KB article to get
more
information about setup network in SBS environment:

Hi Jenny,

Thank you very much for your input. Before I change anything, let me
try
to
describe our setup, and you can suggest how I change it to best server
our
needs.

Currently, we have five IP addresses. Four of these are allocated to
the
server, which is connected directly to the internet. There is no
router.
We
are on a Fiber Optic line, which brings an ethernet connection directly
from
the wall, so there is no router / firewall in place. The server is
just
connected to a hub, which connects directly to the outlet in the wall.
We
give one of the NICs four of our IP Addresses so that it will handle
our
websites. Right now, we have a second NIC in place, which we have set
to
obtain an IP automatically. There is no ethernet cable connected to
it,
so
it simply defaults to a 169 address.

We run a second connection from the hub to a router, which controls our
internal network. The WAN on the router is given a static IP address
(the
one address that we have remaining), so it connects directly to the
internet
as well. I would expect this to act as a separate internet connection
from
our server, as they both use different IP addresses.

What is very strange is that people in other places can access our
websites.
It seems that the only computers unable to connect to our server are
those
behind the router mentioned above. When I try to load our website or
connect
to e-mail, etc., from one of our computers behind the router we simply
cannot
get a connection- it times out. Absolutely nothing was changed on the
internal computers or the router.

Our server is maintained in my home so that I am around if there is a
problem. Our warehouse is in a different location (a few miles away),
and
can access the websites, log in to the server remotely, etc. That is
what
I
meant when I mentioned that we could access from the warehouse, but not
locally.

This was working previously, but after shutting down to install the new
power supply, it stopped working.

I was going to remove the second NIC, and keep only the one that
connects
to
the internet. But, when I do this and try to run the internet
connection
wizard, it says that I cannot use 'direct broadband connection' with
only
one
NIC. Because I am literally connected directly to the internet, can I
still
remove the second NIC and select a different connection option? I just
want
the server to handle our websites and e-mail, but did not know how to
close
ports. In reality, we need only a few ports open to run what we do.

Would I be better to connect the internal computers to the server on
the
second NIC? The only reason that we did not do this is that we do not
want
the extra load on the server in case it would slow our websites down at
all.

I am at a complete loss, so will await your suggestions on how I should
set
my connection(s) up.

Thanks again. I really look forward to your input so that I can get
things
operating properly again.

Hi Rick,

Thanks for posting here.

From your description, I understand the issue to be: users can not
access
the SBS server from some computers but can from other computers
without
problem. If I am off base, please don't hesitate to let me know.

From your description, I understand that you indeed use one NIC to
connect
to the route, another NIC is not be used. In your scenario, you can
remove
the second NIC from the server and use only one NIC. Please note that
after
you remove the NIC, please re-run CEICW to re-configure network
connection
regarding to one NIC scenario. I suggest that you refer to the KB
825763
to
configure network connection.

825763 How to configure Internet access in Windows Small Business

http://support.microsoft.com/?id=825763

If the ISA server has not been installed on the SBS server, we can
enable
RRAS basic firewall to offer basic firewall protection. You can use
Router
to provide more security of your network. It is not recommended we
open
too
many ports in the router since it is very insecure to our network.
Generally, we open the ports we needed to allow some specific
traffic.
You
can refer to the following list:

TCP port Definition
25 Email (SMTP)
80 required for
HTTP
requests for your site
443 required for
HTTPS
requests using SSL, which secures communications from your server and
a
Web
browser
444 Companyweb
4125 Remote Web
Workplace
1723 (plus GRE Protocol 47) VPN
3389 Terminal Services
21 FTP

You open related ports only when you need allow some specific traffic.

To the users can not access the server issue, please check the
following
settings:

I. Please double check DNS and Gateway settings:

1. Set the internal IP of the Router as the Default Gateway of all
client
computers and the server.
2. Configure the internal client computer's NIC to use the internal
DNS
Service (the IP of the SBS server box) as the DNS Server. And there
is
only
the DNS server be configured on client computers.

II. Please ensure enable NetBIOS over TCP/IP on client computers,
please
check the settings.

1. Right-click My Network Places, and then click Properties.
2. Right-click the external network adapter''s Local Area Connection
icon,
and then click Properties.
3. Click Internet Protocl (TCP/IP), and then click Properties.
4. Click Advanced.
5. Click the WINS tab.
6. Click "Enable NetBIOS over TCP/IP".
7. Click OK, click OK, and then click OK.

If not, please verifying to see if the issue is resolved.

If the issue persists, please help me collect the following
information
to
isolate the issue:

1. What is the exact error message you received when user try to
access
the
server? How you access it? using UNC path or others? Please help me
collect
a screen shot of the error message and mail it to my working mailbox:
v-yanniw@xxxxxxxxxxxxx

2. What is the meaning of the sentence "yet the server can be
accessed
from
other places (such as our warehouse)"? How user accesses the server
from
warehouse? Do the computers in warehouse in the same LAN or from
internet?

3. Please run command "ipconfig /all" (no quotation marks)
respectively
on
the SBS server box and one problematic client workstation and email
them
to
me.

I appreciate your time. I am happy to be of assistance to you and
look
forward to your reply!
