No internet access on SBS2008 second server

Hi,

I am setting up a new SBS2008 domain. So far I have a clean installation of
SBS2008 on one box and clean 2008 Server on the second box, both connected
to a router and nothing else on the network. The router is configured with
DHCP disabled. The SBS box has full internet access and the second server
has DNS resolution (e.g. can resolve the IP of any website) but is unable to
open any websites in IE or ping them from a DOS prompt

Both systems have the router's IP as their gateway. Router is on 192.168.1.1
and I have only one network card in the SBS box so can't see that I have
done anything wrong. I am logging into both boxes using the SBS
administrator account I created during setup. I originally installed Server
2008 R2 on the second box and had the same problem with that one before
reinstalling it with the original Server 2008 release to see if the problem
was related to R2

Any ideas? Have I missed something major here?

Many thanks for any help anybody can come up with!

Hi:

Since you did not mention the DNS settings on the SBS vs the Server 2008,
have you compared those?

Is the server2008 set to a static IP? Look carefully at all the settings.
The DNS server for all the systems in your network should be the ip of the
SBS.

Sorry to be so dense, but what do you mean when you say "can resolve the
IP of any website"?

SBS is set to static address at 192.168.1.2
Second server is auto-configured and IPCONFIG shows DNS is set to
192.168.1.2 (the SBS box) and gateway is 192.168.1.1 (the router)
Haven't checked the DNS server on SBS yet but as this is default settings
after installation I would assume it will be it's own IP
Basically all the networking settings are default out of the box settings. I
haven't changed anything after my initial OS installations. SBS set itself
up with this static address and had full internet access directly after
installation. I also ran the connect to the internet wizard on SBS but this
hasn't changed anything as far as I can see as the router was already
detected during SBS installation

I did however get a message from SBS saying the router could not be
configured to open ports which is strange considering uPnP is switched on in
the router (Draytek Vigor 2800VG). So I manually opened all the ports it
told me about to the SBS IP, and also port forwarded the same ports to the
SBS IP, put the SBS server's IP on a DMZ, disabled the router firewall and
added my ISP's primary and secondary DNS servers in the LAN settings on the
router. None of these actions gave me internet access on my second server
and I can't think of anything else I can bypass or disable on the router,
except perhaps resetting it to factory defaults and seeing if SBS can
auto-configure it then...

When I say the second server can resolve IPs I mean if I go to the CMD
prompt and try to ping a website by entering the URL, e.g. www.bbc.co.uk it
will return the IP of that website, but then it fails to get any replies to
the ping message. This makes me think DNS on the SBS server is working as it
should but something is obviously still wrong

Cheers

Ok, not required, but by custom servers have a static ip address so they
are always in the same place. <g> You could accomplish the same thing with
a dhcp reservation, but that would be unusual.

A remote url that resolves but does not ping may just mean the edge device
is set to not respond to an external ping request.

Servers, by default, do not gracefully connect to web sites. What errors
are you seeing in IE when you try to open, for example, support.microsoft.com,
one of the few non threating sites you could reasonably browse from a server.

I suspect an issue with the DNS forwarders. Can you please post the unedited
results of the command:

ipconfig /all > c:\iptest.txt

from both servers.

Ok I went back and compared the DNS settings on both servers and they were
identical. I also went into DNS Server on the SBS box and added in DNS
forewarders for my ISPs primary and secondary DNS. Still no joy

I then reset my router back to factory defaults, re-disabled it's DHCP
server (which got switched back on again) and now I have internet access on
both servers. So the router was causing it...

.... I then removed the DNS forwarders from the SBS box since they were not
there by default and still internet is working perfectly

Thanks for the help anyway... I do have one more question: why doesn't SBS
2008 need these DNS forwarders? On SBS 2003 these were entered in the ICW
and I seem to remember were set up automatically in DNS
