Since you are on a NAT box, I believe this is coming from withing your LAN. There does not seem to be a physical problem, as I can set a static IP address that will work just fine. In this example I have excluded a range of IP addresses, to, and a single address, I know you've said you've tested that, but if you have a rogue DHCP server, and yours isn't authorised, that will cause mayhem.

I rebuilt the scope, I unauthorized and reauthorized the scope, and I reconciled the scope with the registry, in short everything that I could think to do when rebuilding the scope Per a correction to your earlier comment, the Netopia inside addr ( is configurable..

You shouldn't, and can't disable the firewall on SBS client machines bacause it is controlled by an SBS domain policy.

If so is it responding and are those responses getting to the client?   Otherwise all I can recommend is to do the standard check the event logs, make sure the navigate here Autoconfiguration IP Address. . . : Subnet Mask . . . . . . . . . . . : Default Goto HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Connectivity\ICW and check if the "Last_1st_Nic_Guid" is also set to this Guid you noted in step 2.
