i have a dhcp server serving multiple subnets.
when the link goes down the workstations go to the default address
169.254.?.? what would be the best solution to allow users to get to
the local resorces until the link is restored?
can i change XP to use a different default address range or will it be
something i need to handle in routing?
One thing you can try is configuring the clients with an alternate
configuration in TCP/IP properties. This is a static configuration that is
used by the client computer when the computer is configured as a DHCP
client but the DHCP server is unavailable.
The only catch is that the configuration is static -- so you could
conceivably cause an IP address conflict if you aren't careful in how you
set it up. One approach would be to assign reservations for clients on the
DHCP server, and then use the same reserved IP address in the alternate
configuration for that client. Another possibility (though I have not
tested this) is to create an exclusion range on the DHCP server and only
create alternate configurations from the IP addresses in the exclusion
range.
A couple of Help topics for you:
