2 default gateways on windows server.

Hi,

We have a segment connected to 2 routers, we planned to add one more default
gateway to the windows servers so that one router can be a backup router.
Here is the setup :

Setup 1
router A : metric is automatic
router B : metric is 23

Setup 2
router A : metric is 1
router B : metric is 2

I notice that the default automatic metric is 20. At first, both setup were
working but suddenly it point to router B (the backup router), even though
router A is up and running. I thought maybe there was some connection issue
to router A, then it points to router B but even though if it happens like
that, does it supposed to point back to router A once router A is up and
running ?

Please help...

Thanks.

Regards,
Zul

No - what you are experiencing is the expected behavior unless you are
running a routing protocol - ie. when the preferred gateway fails, Windows
will switch over; but it will not switch back unless you reboot. See:
