Server and Clients unable to browse internet

I regret to say that I am a newbie...but I have installed and reinstalled SBS due to a myriad of DNS issues.  Anyway the server seems to be running perfectly except that neither my Server nor Clients can browse the internet?  They can all ping things on the net fine (i.e. google.com, etc.) but for some reason the sites won't return to the brower.  It just times out?

Any ideas???  Please help! :)

Sounds like a DNS issue, can the server browse the internet?
Run the Internet connection wizard in the to do list again.
Have you 2 network cards or 1?
Run the command prompt and type: ipconfig/all and post the results.

Which version of SBS are you using?
How are you conected to the internet?
Could you post an Ipconfig /all for both the server and a workstation?
Could you also post a tracert to an external ip address from a workstation?
How is your DNS Server currently configured?

Thanks,

I have 2 nic cards and neither the server nor clients can browse. I don't understand why I can ping everything and get a reply but it won't return to the browser.  I am running ISA server also...  Addtionally I have several other devices on the network like Vonage VoIP boxes and they are working fine...so somehow they are resolving but the client and server won't do it.

How are you conected to the internet?           Direct connection thru Router (serving me a public IP)
Could you post an Ipconfig /all for both the server and a workstation?

The tracerte hits my DSL box first but seems to be skipping the local DNS...
Is the ISA server part of SBS if so it's SBS Premium edition you using. Is this a new setup or did it just stop working?
So you have two network cards in the server, one connected to the netwrok switch and one connected to the router?
Has the broadband router DHCP enabled? if so make sure the nic in the server that is connected to this is obtaining its IP and DNS setting automatically.
See if you http://216.239.59.104/ (google.com) resolves in either the server browser or the client.
What way is the ISA configured?
 
Is the second Ipconfig info for the Server?
Have you installed the Firewall client on the workstations?
What is your ISP's dns servers?
If you go into Administrator tools and click DNS, a new window comes up, right click on the server and select properties. Is there a forwarder setup in there?


David
You mentioned premium for SBS 2003, but the ISA is it 2000 or 2004?

David

This is a new setup and I do have SBS Premium Edition.  ISA was loaded from the Premium Applications CD

Yes..the second IP config is for the server.

The clients do have firewall running but it is controlled by some Server Group Policy.

My ISP's DNS Servers are 66.73.20.40 and 206.141.193.55 (I have my DNS Setup to Forward Unresovled Requests to those)

I belive the ISA is 2000.

I can ping 216.239.59.104 and trace it but it isn't resolving properly within the browser.
When service pack one came out for SBS 2003 they upgraded from ISA 2000 to ISA 2004, you should contact Microsoft and see about getting the media updated to Service Pack One and get the added benefits of 2004.

Isa has its own Firewall client that you can install, this forwards traffic through the ISA server from your client machines, this is different from the firewall on your workstations.
To install the client goto \\sbsserver\mspclnt

Or you could just change your browsers configuration to use the isa server, but this would only affect your browser any other programs accessing the internet would be required to be setup as well.
In IE goto tool, Internet options, connections, and press the lan settings, select use proxy server and enter 192.168.1.1 as the server and port 8080.

That should get you surfing.
I recommend checking out either Harry Brelsford's series of books at www.smbnation.com or Eriq Neale's book Small Business Server 2003 Unleashed.
Just to help you out and deeper understanding of how the technoloigy integrates in SBS.

Hope this helps,

David,

I tried that out and I am still unable to browse... :(   BTW I do have ISA 2004 not 2000 as previously stated.

This is driving me insane to say the least....  I am basically getting a timeout in my browser when attempting to load pages.  This is despite the fact that I am getting excellent ping replies...

Any other ideas...?

Cory
How did you create the users? Using the sbs wizard or active directory Users and computers?
Could you post the complete timeout page that you see in IE?

Thanks

David

I created the users with the SBS wizard...  I will try to get the timeout page posted.  I keep having to log off my cell modem to work on the net and then I come back to see if you have posted anything else.  It would be easier if I had an internet connection... :)

Cory
when you said you were able to ping fine....

you did a ping www.google.com and got replies?


did you run a tracert www.google.com? can the results of both of these.

if you can ping using a host name the DNS must be working somewhere, or www.google.com is cached.

Also when you try to browse to a site, in the status bar does it have ip address or www.google.com?
Avatar of specicg

ASKER

already done...I know that DNS is working..

I am trying to figure out why results are not returned to the browsers

Any progress on the timeout errors?

specicg,

If you haven't already installed the Server 2003 Support Tools from SBS's Disk 2.  (If you have installed Service Pack 1 on your SBS, then you need to download the SP1 Support tools from here:  http://www.microsoft.com/downloads/details.aspx?familyid=6EC50B78-8BE1-4E81-B3BE-4E7AC4F0912D&displaylang=en)

Then, open a Command prompt and move to the C:\ root directory and run a "netdiag /l"  the /l will create a file on the C drive called netdiag.log.  You can then post the contents of it here.  Feel free to censor anything that you feel would be compromising, howver I ask that you do so with asterisks (*) because that symbol is not used in those reports normally.  Otherwise, please post the report in it's entirety.

This will help to see what's going on for you.

Jeff,

Thanks for your help with this...  I have rebuilt this server now four times.   Each time presents a new issue.  As the server sits right now, there are now premium applications installed.  When I rebuilt it the last time I didn't install the ISA Server or SQL Server update.  I will need to install these after I get everything working properly.  

During the last install, I didn't modify anything and let SBS do all the work as far as configuring NICS etc.  As it stands right now, the SERVER and the CLIENTS are able to browse the internet, but the clients are unable to connect to the server via HTTP.  As such, I am unable to use the connectcomputer feature to add the clients to the domain.  It has been very frustrating to say the least...  

I can ping the server from the clients...using name or IP address works fine.  I can ping the clients just fine from the SERVER also.  DHCP is working fine on the SERVER and issuing IP addresses okay over the internal nic.

The weird thing is that the clients and server can browse the internet fine, but not connect to sharedpoint services...  

As you requested, here is the netdiag results.  Please help! :)

In your original post you said that you could not browse to the internet, but your last post says that you can access all http servers external to your network?

Is the problem just that you can not access your own internal network Webserver?

Hi David,

The problems have changed due to me reinstalling SBS for the fourth time.  I can browse to any external websites from all clients and the Server. I reloaded ISA and am now able to connect to the server via but I am unable to use the ConnectComputer wizard to add machines.  It eventually times out and gives me an error saying the list of users and computers cannot be found.  I also am unable to make normal network connections to the the server (i.e. \\server\sharename).  

The server DHCP server is working fine...I think

I can ping anything by name or IP, but NSLOOKUP only responds with the server.  None of the clients seem to be registering properly in DNS.  I have tried flushing and forcing registration, but that doesn't work or help matters.

My clients are also logging this msg in Event Viewer

The Network Address Translator (NAT) was unable to request an operation of the kernel-mode translation module. This may indicate misconfiguration, insufficient resources, or an internal error. The data is the error code.

Can you put up complete ipconfig information from the server and workstations.

I finally figured it out.  I new that it had to be something really stupid to have taken three days of my time.  One of my two NIC drivers was wrong.  While it seemed to work okay, I realized that the problems would reverse themself when I swapped the NIC's LAN/WAN locations and settings.

I would have never guessed it until I looked a little closer.  Thanks to everyone for their help...  We'll split the points between Jeff and David for all of their efforts.  

The only real benefit to this mess was that I learned a great deal about SBS doing my trouble shooting research.

Thanks again!
