SBS DNS not working for all client workstations
I am in the process of adding 8 new client workstations (all identical) to a SBS 2003 SP2. I have used http://server_name/ConnectComputer sucessfully to add two of the computers onto the domain. Both are configured for dynamic ip address via DHCP, however I'm having problems with internet connection. One of the workstations connects ok, but the other will not connect. (Page cannot be displayed error). On the problematic workstation I can ping www.google.co.uk and ping 66.102.9.104 sucessfully, but cant get an internet connection. I'm thinking it could be a DNS error, but then why would it work or one workstation and not the other, additionally why would it resolve www.google.co.uk if dns was incorrect.

Hi Daniel,
There is no proxy set on lan connections and there is no filtering on the gateway (172.16.1.200).
Thanks

1. Try installing Mozilla Firefox to see if it's an IE issue.
2. Also test anther protocol ie FTP to see if that PC can get out.
3. Make sure you don't have any anti-virus/software firewall preventing access (disable all to test).

I've just added another brand new workstation onto the domain and the same problem is happening. No internet connection. It gets it IP address ok from DHCP, but when I try ipconfig /renew I get the error:
An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out.

Is the SBS server using the same class B subnet mask? (255.255.0.0)
bertster,
You can verify if your DNS is working..
Follow the steps:
1) Go to Start
2) Click RUN
3) Type: CMD then press ENTER
at the command promt
4) Type: ipconfig /flushdns
5) nslookup experts-exchange.com
The reply should be similar to:
Non-authoritative answer:
Name: experts-exchange.com
Address: 64.156.132.140
If it resolves .. it means your DNS is working... then just follow the advice of Daniel.
I hope this helps.

Chatxfalcon,
Yes nslookup resolves experts-exchange to 64.156.132.140
Seems DNS is ok.

Can you test Firefox to see if it's an IE problem.
You could also try a local web (SBS) server - http://companyweb. That should definately work.

Firefox now installed but is also not working - address not found

Can you run the following from command prompt and post.
tracert 61.88.88.88
tracert 61.88.88.88
Can you specify what the firewall (or the device at 172.16.1.200) is?
And does http://172.16.1.33 bring up a SBS 2003 website?

So to sum up :
-ipconfig /renew gives a timeout error even through the system already got an IP address from DHCP previously
-you can ping and tracert to an internet IP address but not web browse to it with IE or Firefox - no filtering or proxy involved
-the pc is configured identical to another pc that is working properly
-the pc can't hit http://companyweb (altho that may not be enabled on the SBS server)
Can you ftp to the internet from a command prompt? (i.e. ftp ftp.microsoft.com)

Yes your summing up is correct
I CAN ftp from a command prompt (just connected to ftp.microsoft.com)

And what about the software on the PC:
Antivirus?
Firewall?
"Security" Software?

Nope - both fail with page cannot be displayed.
Incidentally the ipconfig /renew now works - it once again sees DHCP server

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
However, since you can ping 66.102.9.104, that means you are actually getting to the internet.
The first thing that comes to mind is to check that no Internet Explorer proxy is set up on the problem workstation. (Tools/Internet Options/Connections/LAN Setting - uncheck use proxy server for your LAN)
From what I can tell, your SBS server is 172.16.1.33. Your internet gateway is 172.16.1.200. You can check to see if there is any kind of internet filtering configured on the 172.16.1.200 device.
