Cannot access the internet from a 2nd server

September 30, 2010 at 08:36:34
Specs: Windows Server 2008 Standard
I have added a 2nd server (windows standard server 2008) to my domain which is on a SBS server 2008 and which acts as my DNS server. I have another computer in this domain as well. I can access the internet from the SBS server and from the computer but I can't access internet from the 2nd server (local access only).

I am using fixed IP addresses. I can ping the 2nd server and the router from both the SBS and the computer. I can only ping the SBS from the 2nd server, not the other computer or the router.

Here are the configurations:
DNS server (SBS):
IPv4 address: 192.168.0.2
Subnet mask: 255.255.255.0
Default gateway 192.168.0.1

Computer:
IPv4 address: 192.168.0.3
Subnet mask: 255.255.255.0
Default gateway 192.168.0.1

2nd server:
IPv4 address: 192.168.0.4
Subnet mask: 255.255.255.0
Default gateway 192.168.0.1

The TCP/IP settings you show look correct. However, you should have but didn't include the DNS setting. Compare the DNS setting on the client and the server that doesn't work. If they're not the same, then that's your issue.

Typically, the DNS on your DC (SBS) should be forwarded to your provider's DNS. All clients and servers within the domain should point at the DC for DNS.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

Yes, I should have included DNS:

SBS (DNS server):
Preferred DNS: 192.168.0.2

Computer:
Preferred DNS: 192.168.0.2

2nd Server:
Preferred DNS: 192.168.0.2

Both the DNS server and the computer are getting internet.

Try to ping a public ip address from the second server.
If this works fine, try to ping e.g. google.com.
If this doesn't work, you have a DNS problem at the second server.

Post back the result.

I pinged the actual IP address for google from 2nd server and it still timed out. What is interesting is that when I pinged "google.com" from the 2nd server it displayed the IP address for google. It knows where to find google but can't ping it.

Yep, so it can find google.com and resolve the name to it's ip address, but ICMP Request and/or ICMP Reply is blocked.
Any kind of firewall running on second server (windows firewall or third party firewall)?

On the 2nd server, Windows firewall is on. Is there a group policy that I should update?

If the server is behind a router with firewall, I would test to simply disable the firewall at the second server for testing.

If this will work, it shows you the way, for further research.
