Re: Urgent! New router and big disaster

Both NICs should point to his internal IP. The SBS DNS server, running on
the internal IP, will then satisfy external requests via either forwarders
or 'root hints'.

C'mon, we're getting close. Don't spoil it.

You're getting close. Since you can reach an external web site by using
its IP it means that your problem is now DNS. I don't see how your
settings could work. In the TCP/IP properties for the external NIC, you
need to specify an external DNS server for DNS, instead of the server's
own IP address. You should do that in the CEICW, that way it will set up
the DNS forwarding to work correctly. When the CEICW asks you for the
configuration for the external NIC, use:
IP Address 192.168.0.99 (See Note 1)
Subnet Mask : 255.255.255.0
Default Gateway: 192.168.0.1
DNS Servers: 192.168.0.1 (See Note 2)

Note 1. 192.168.0.100 looks like an address in the DHCP range of the
router. You should give your SBS a fixed external address so you can
forward ports to it reliably in the router. I don't have the D-Link doc
but x.x.x.99 should be outside its DHCP range. If not pick another one.
Why do that if the SBS is the only computer connected to the router?
Because some day you might try to debug something else, plug a computer in
the router while the SBS is off or disconnected, then plug the SBS back in
and discover that the other computer has now been given the address you
thought was the SBS's own. Then of course RWW and all those goodies quit
working. Play it safe. Use a fixed address outside the DHCP range of the
router.
Note 2. Normally the router will forward DNS requests. You may be able to
speed things up by specifying the IP address of your ISP's DNS servers
instead of the router -- the router will just pass that through instead of
actively forwarding.

I checked the binding order and the Server Local area connection is at the
top.

I should have been more clear about internet connection..
- when we open internet explorer the company web is shown, when we type
in
an address... http:www.google.ca, we get page cannot be displayed. But if
I
type the ip address 65.98.45.220 the webpage loads. (this is true for
Both
the SBS and client stations)
I just read somewhere in another posting about nslookup.exe, and thought
I
would give it a try. I got this..
***Can't find server name for address 192.168.16.2: Non-existent domain
Default Server: Unknown
Address: 192.168.16.2
( I found that in the DNS - clicked my server name and ran the lookup
tool)

Check Binding order
------------------------
Right click My Network Places...Properties. Highlight the Internal NIC.
Then
select Advanced...Advanced Settings from the top menu for that window.
This
will check the bindings.

The Internal NIC should be displayed first followed by the External NIC.
If
not, move the Internal NIC to the top of the list.
The Internal NIC should have File and Printer Sharing bound
(checkmarked) to
the TCP/IP Protocol.
The Internal NIC should have Client for Microsoft Networks bound
(checkmarked) to the TCP/IP Protocol.
------------------------

Is the Internal NIC at the top of the list?

After
running the internet connection wizard, no internet was available for
either
the SBS or the Client by using the test page www.dnslookup.com, but
each
can
view 65.98.45.220.

What is 65.98.45.220? If neother SBS server nor client workstation had
Internet access, how could they view anything at this public (Internet)
IP
address?

Been having a a lot of trouble. The orignial router died and now we
are
using a D-Link 604. My problem is this:

1 -I have the set up done just like this...

http://www.smallbizserver.net/Default.aspx?tabid=266&articleType=ArticleView&articleId=76

The Current ipconfig/all from server is this
Server Local Area Connection:
Connection-specific DNS Suffix:

Any ideas?

Other info... Before I ran the internet connection wizard, I also
disabled
the UPNP on the router itself. I have checked the DNS Service and it
is
running, also is the DCHP Service.
I wonder if I may have missed a firewall setting on the router as
well.

Hmmm. In a 2-NIC setup changing the router (which feeds the WAN side
of
the
SBS) should have nothing to do with the inability of the clients to
login
to
the domain. Completely separate networks. The IPconfig for the
client
shows
that the client is not able to get an address from the DHCP server on
the
SBS.

Now, a problem could occur if the physical net was configured to use
the
router's LAN switch to connect the workstations (both SBS NICs into
the
same
switch) which in theory should work but is of course a very bad
practice.
If
that is the problem, try to fix that, using the diagram in the SBS
documentation (such as it is...). Assuming that this is not the
problem...

First check whether the DHCP service is running. If it is not, start
it,
then try to figure out why it did not start in the first place.

If that does not fix the problem, go through the following steps:

1. Verify that the workstations can physically connect to the LAN
side of
the SBS. Since it looks like the workstations are set up to use DHCP,
a
quick and dirty way to do that would be (a) disconnect everything
from
the
router then (b) to move the cable from the LAN side NIC of the SBS to
a
LAN
port on the router then (c) turn on the router, give it time to boot
and
do
an ipconfig -reset on a workstation then check whether it got an IP
address
from the router and that it can ping the router. If that doesn't
work,
first
do a deep reset of the router and try again. If after that it still
does
not
work, look for a bad cable or bad switch in the LAN or some other LAN
config
problem.
2. Assuming that step 1 is fixed, take this opportunity to log into
the
router and verity that it is set up correctly. It should have DHCP
turned
on
and have its WAN side configured properly, including the ISP DNS and
gateway
addresses if the WAN side of the router is not using DHCP. Don't
bother
with
port forwarding yet. Making sure that the firewall on the workstation
is
enabled (or using a test laptop instead of the workstation), connect
the
WAN
side of the router and check that the workstation can connect to the
Internet. If that works, then the router should not be a problem and
you
can
focus on the SBS. If that doesn't work, pretend that the router is
working
for the purpose of step 3, but you will need a router...
3. With all physical connections correct (as in the SBS documentation
diagram for 2-NIC setup with a router), run the CEICW. Use the
vanilla
settings. While you are at it, set up a LAN side address of
192.168.x.2
for
your SBS, where x is anything excep 0, 1, 2 or 13. This will allow
you to
substitute any router (at least from the brands I've tried) without
having
to worry about subnet conflict between the WAN and LAN side. When it
comes
to router UPNP say that your router is not UPNP, and look up the
"More
Info"
that tells you which ports you will need to forward on the router.
Port
forwarding on your perimeter device is something you probably want to
be
able to control yourself. Also, if you control port forwarding on the
router
yourself, you can replace the router at will without ever needing to
change
anything in the SBS configuration.
4. Check the Services to verify that the DHCP service is running. Go
to a
workstation and verify that it can get an IP address through DHCP and
that
you can ping the SBS--it should show up as the gateway and DNS server
in
the
IPconfig for the workstation. If this doesn't work, then you have a
more
serious problem with your SBS. Call for help.
5. If steps 1 to 4 succeeded, then try to king a known good test
address
(e.g. www.dnsreports.com) on the Internet from a workstation. If that
doesn't work (not found), try to ping a known IP address (e.g.
65.98.45.220). If that works but pinging by name did not work, you
have a
DNS problem. Check that the DNS configuration in the CEICW is
correct. If
you had made manual modifications to the SBS DNS settings, go back to
your
setup nodes and try to undo them before running the CEICW. If that
still
doesn't work, call for help.
Let us know how you've done. Sleeplessness induces people to make
strange
errors... so be careful.

It looks like new router configuration was different from one that
died.
Post output of "ipconfig /all" from server and one workstation
connected
to 24 port switch.
Should be able to give you simple instructions to get back to where
you
where before this incident.

quick brief on orginal setup
Dell Power 1800 server running SBS2003 standard with 2 nics
1 D-link 8 port router & 1- 24 port switch
D-link connected to ISP with a stactic ip and server- onbard nic
connected
to switch.
Orginal install went off with out a hitch including all updates
ect.
For
a
week clients could communicate with server.

Yesterday the router dies, and I quickly swapted it with another
D-link
router this one smaller -only a four port. When the router died,
other
than
no internet access, the client machines could still connect to
server.
After I swaped the router everything was still fine.

This morning, I had to go clean up my network room and wires.
During
this
I
shut down the server, and removed of from the room. It was down
for
about
5
hours.
Then I set it back up, all the same- i didn't touch a setting, and
now
my
clients can't login. The administrator can log in client machines,
release/renew the ip address, look at network places, see the
server
but
cant
connect. No internet access either.

Okay so back at the server -no internet connection but can see the
internal
website. The external nic is set to auto get ip from router, but
the
primary
dns is the ip address of the local nic. When I change that to the
ip
of
the
router I can get internet on the server. Ran the CEICW... doh! The
wizard
poped up with that the router is a plug in play and it wanted to
configure
it. Now everything is so totally messed.
I cant get any clients to log in but when i set the ip on the
external
nic
back to the router ip, I can reach the remote server login page on
my
laptop.
I have ran the change server ip wizard, but nothing.

Please I need to have this whole thing back up and running by Mon.
morning,
so please give very deatiled instructions if ya got them. I have
been
going
on less than 3 hours sleep, and if you can come up with a less
than
perfect
quick fix until next weekend, I am all ears.

Thanks
