have tried adding two gateway TCP addresses but does not seem to switch between the two.
one gateway is for a router the other is for a server
is this possible?
To my knowledge, you can not specify 2 default gateways for one machine, except maybe if it has 2 different interfaces on 2 different subnets. Why would you need a gateway address to point to a server?
There are only 10 kinds of people; those who understand binary and those who don't...
You need a gateway address to point to a server if the server is unreachable through the router interface. You can add a static route to the machine using the "route add" command from the command prompt...just do a route /? , and that will get you going.
Will this failover still work if something beyond the first gateway does not respond, or is it dependant purely on the gateway itself having the problem before the failover?
have heard using 'route add' from the command prompt is a better way of adding gateway' rather than the metric adjustment in the adv. props... ne one know why?
[route add /help]
The issues are different. Using the GUI interface to TCP/IP properties, Advanced, allows you to add a second Gateway and adjust the metrics if required.
For command line access the best tool you have is netsh.exe under Windows 2k and XP:
What happens if you add multiple default gateways, via the advanced properties, all with same metric? Will this load share? If not how can I load share across three or four gateways (multiple ADSL connections).
The more you know, the more you realise there is to know....

The use of multiple gateways can be configured to use Dead Gateway Detection, but the only way that it will check a gateway again that has been "declared" dead is if the gateway now in use also goes dead or the box is rebooted.

Adding a static route is the way to go since you are telling the computer how to handle the traffic versus relying on an automatic mechanism to fail over (and may not work as advertised).
