Strangely enough "route print" shows a default route, but the default
gateway is missing in the network connection properties, and I have to
manually reenter it to restore Internet connectivity. Anyone got any
ideas what's up?



Possibly related is that the Internet router actually tries to proxy ARP
for all IP addresses, which rather confused the configuration wizard.

If it happens again, open regedit, navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<GUID>\DefaultGateway

and double click the DefaultGateway value.

See if there is a blank line before the actual default gateway IP.

If so, it is most likely the issue in KB 973243.

973243 The default gateway is missing on a computer that is running Windows
Server 2008 or Windows Vista after the computer restarts if the default
gateway is set by using the Netsh command
http://support.microsoft.com/default...b;EN-US;973243

You can install that update to prevent it from happening in the future.

Thanks, this does indeed look like the problem. However the Microsoft
website only offers a Vista hotfix. As a workaround, can I simply
correct the default gateway setting in regedit?

Vista 64 = SBS 2008

It's the same code. Install it.

As Susan said, it's the same codebase so even though the hotfix says Vista
it also applies to Windows 2008/SBS 2008. You can still want to fix it
manually. The hotfix fixes netsh so that the default gateway will not be
written into the registry like that again.

By any chance did you change routers or change the nic from DHCP to a static
IP or static to DHCP?

Thanks, I will install the hotfix next time I reboot the server.

The nic would have been DHCP to start with but I used the Connect to the
Internet wizard to change it to a static IP.

Okay, thanks.

I had this problem last week on a Dell 2008 SBS Server.

The hotfix worked, after 2 reboots, and solved the default gateway problem.

However, as a consequence, I can now no longer access Printers or Network and Sharing Centre.

If you try to open either, it just takes forever, but doesn't ever error. You just have to close the window down.

It does mean we can't add/manange printers now.

Any clues/ideas/help would be appreciated, it's driving me mad.

Just to follow this up.

Removing the Hotfix has resolved the problem, without re-introducing the Default Gateway issue.
