Browser fails to display websites
Posted on 2014-04-09
Hi,
I have an existing SBS2011 network with 192.168.2.x and all is working fine.
I am currently setting up another SBS2011 network for a customer. Since I needed an internet access, I put this new SBS2011 and one PC under another Internet router (192.168.1.1) under current DLink router (192.168.2.1).
In fact this new SBS2011 will replace SBS2003 with same IP network (192.168.1.1).
So I thought I could create a real environment (192.1687.1.x) in my lab and set up everything before delivering the SBS2011 to my customer.
Things work mostly fine except the internet access.
I am having a hard time surfing the Internet from both SBS2011 and PC1.
Google is just about the only website that comes up ok. Other websites like Yahoo will take forever and most websites won't even come up.
The funny thing is I have installed LogMeIn Remote access program on both SBS2011 and PC1 (in 192.168.1.x network) and I can access them w/o a problem from anywhere.
I tried to connect to a terminal server from these computers by entering the domain name in Remote Desktop and it failed, but if I used IP address, it worked.
Basically it fails to resolve xxx.com into IP address, I think.
Thanks for your help in advance.

It is definitely a DNS resolution problem. Does the ISP provide a DNS server address? Your SBS are using their own IP address for DNS. Which is fine as long as the DNS server on each machine is setup and working correctly. Another option is to use Google public DNS servers 8.8.8.8 and 8.8.4.4. While each machine on your network won't have a DNS name every other website should work.

"Does the ISP provide a DNS server address? "---> Yes. The DLink that is connected to the Cable Internet receives DNS address like below:
Here is DLink WAN and LAN Status
IP Address : 65.60.x.x
Subnet Mask : 255.255.248.0
Default Gateway : 65.60.x.x
Primary DNS Server : 204.194.232.200
Secondary DNS Server : 204.194.234.200
LAN
IP Address : 192.168.2.1
Subnet Mask : 255.255.255.0
DHCP Server : Disabled
Here is WAN and LAN setting of the 2nd Router connected to DLink Router above.
IP address 192.168.2.100
Subnet Mask 255.255.255.0

Primary DNS 192.168.2.4

I assigned ISP provided DNS addresses in SBS2011 of 192.168.1.x network in replacement of 192.168.1.2.
Primary DNS Server : 204.194.232.200
Secondary DNS Server : 204.194.234.200
And it works. I can visit any website. Thanks for your help.
The ip address is the same for the router #2 and pc one on the first section ( 2.100 ).
This should cause an ip conflict. Not allowing router2 to receive all the packets. But let's assume that is not the case.
From clients SBS:
Step 1) ping 192.168.2.1
If not successful routing issue.
Step 2) ping www.google.com
If not successful either Internet or DNS.
Step 3) ping 8.8.8.8
If successful and Google ping fails. DNS
If fails. Internet
My gut instinct says the problem is DNS. In which I would change the SBS server to use 8.8.8.8 instead of itself.
