Re: Loosing Internet Connection

I agree with SteveB and Marina that you should address all issues....BUT, I suspect this isn't your problem.

first, as already asked, an ipconfig /all on your server would be helpful. Secondly, you mention that your DSL gateway is bridging, so we will assume, for the moment that it doesn't hold an external IP address. If this assumption is wrong, please speak up!

You said you are using the linksys as a firewall/router. Does this mean it has an external IP? And if so, does the server also have an external IP? Or is it configured with a private IP via NAT? Of course your ipconfig will answer this question, but with either answer I'll have to admit some confusion which I will explain now, so that you can perhaps provide an answer along with your ipconfig.

If your linksys is runing in a NAT configuration, how did you remove it without breaking your entire network? For this to work, you'd need some head unit holding at least one external IP and routing for you to verify that the problem persisted.

Alternatively, if your device holds an external IP and your SBS server is confgured to utilize a NAT address then your ping test should NOT have pointed to the server as a problem. The server would not respond to a ping on the external address. If pings were timing out and then returned on their own, you can most assuredly start looking at the network structure (cable, devices, software) of everything between the linksys (INCLUDNG the Linksys) and the internet...as that is the device that should have been responding to the ping....

Hope that helps you narrow your search,

-Cliff

As Marina says you should take action on this and any other issues the BPA flags.

Thanks for the response.
Currently we are running SBS 2003 SE. After I ran the SBS BPA I received
warnings on a second NIC wich is disabled, so I'm ignoring this for now.

One thing that caught my eye was:
EDNS is Enabled:
EDNS is enabled on this server. Some of the routers or firewalls may not
support EDNS. You should disable EDNS on this server. To do so, click Start,
and then click Command Prompt. In the Command Prompt window, type dnscmd
/Config /EnableEdnsProbes 0 and then restart the DNS Server service.

Is this a problem? Should I perform the recommended task?

Not a good idea. Only the SBS IP address should be in the DNS setting for
both workstations and the server-no external ISP DNS IPs.

Ralph is this SBS SE or PE (with ISA 2004 installed) and 1 or 2 NICs. Is SBS
2003 SP1 fully installed and then have you installed Windows 2003 SP2?

Run the SBS BPA to see if it shows any problems that should be corrected.
