Here is the forwarders tab, completely empty, should I set something up in it?
Click to expand...

Press the Edit button.

In the dialog that opens enter the IP address of the DNS server(s) you want to use.

Make sure it's happy (green ticks).

Press OK to close the dialog.

Press OK or Apply to finish.

And here is a screenshot of doing nslookups, it's failing to resolve I think :(

It looks like it's trying to use your router for DNS.

What does an IPCPONFIG /ALL on the client machine show.

On my machine I get the following for the nslookup:-

Code: 
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\xxx>nslookup
Default Server:  xxx-xxx.local
Address:  192.168.10.2

> salesforce.com
Server:  xxx-xxx.local
Address:  192.168.10.2

Non-authoritative answer:
Name:    salesforce.com
Address:  204.14.234.33

192.168.10.2 is my SBS 2011 server.

Workstation is still pointing towards the wrong DNS server.

With DNS fowarders, I'll add in your ISP's DNS address first (as it should be more local), then Google after.

This is on my own pc, it's not connected to the domain but it uses the same router
 
The router is irrelevant. An IPCONFIG from a non-domain PC isn't going to help with diagnosing a domain DNS problem.

Assuming you want to use DHCP for the clients you're going to have DHCP server running. This is going to either be the SBS server or the router.

The DHCP server (wherever it is) needs to be configured to tell the clients to use the IP address of the server for DNS. DNS is used for more than just allowing web access. If it isn't configured correctly the domain won't work.
 
If it's a client system on the domain that is the issue, then doing it off your non-domain system is of little use.

Redo an 'ipconfig /all' from a system connected to the domain.

Secondly, you shouldn't need to manually enter DNS settings to your workstations; the DHCP server (or router in this case), if setup correctly, should be handing out the DNS IP (ip address of the SBS server).

Edit - bremen1874 got there first....

The router's DHCP service is enabled and pointing at the domain server @ 192.168.10.2

I've just checked to make sure, the domain servers DHCP server service is stopped as it should be, cause (correct me if im wrong) two DHCP servers on the same LAN will make everything go mental ? :O
 
Here is an ipconfig /all from a client PC directly connected to the domain

If I were you I'd switch off DHCP on the router and use the server. I'd set the DNS forwarders to whatever two servers are provided by the ISP (often can be picked out of the router status page). Also, I used to make sure mailbox and filesystem quotas are off, but that's a personal preference. I prefer to use statics IPs out of the DHCP pool for printers too.

Btw. you have to use the Windows server for DNS because it contains records for finding a server to authenticate your logon credentials.

Sounds like you need an hour or two with someone on-site that's Microsoft certified.
 
1.Disable DHCP on the router.

2.Use the SBS Console 'Connect to internet wizard' to setup the networking on the SBS server. It will ask you what IP address the server should use and the IP address for the router. It will then setup DHCP, networking and will also create the remote certificates for you.

3.Run the ‘Set up your Internet address’ wizard to setup exchange and the internal sites.

4.Setup a DNS forwarder to point to your ISP's DNS or your router.

5.Turn off root hints.

6.Depending on your ISP, it’s also a good idea to disable EDNS probes. Run an administrative command prompt and enter:

dnscmd /Config /EnableEDNSProbes 0
