I have an instance where I need to multihome a laptop.
Situation is fixed IP at office, fixed IP at home.

For some reason either one or the other set of addresses
works. What has been done is in the Networking tabs, under TCP/IP,
Advanced, there are two sets of addresses, two gateways and under the
DNS tab there are 4 DNS servers. Two for in office and two for out of
office.

Problem is only 1 set of addresses works at a time.

Any tips? Does the Windows Firewall know how to deal with this?

Use NETSH to create a script to run to change your location (work or home) -
you will have to run this when you want to switch.

Another option may be to use the Alternative Configuration in networking,
but that may only work if the initial connection you are trying to make is a
DHCP one. Do you have a way at either location to use DHCP but have the
server/router assign you the same "static" IP each time by MAC address?

No, that was part of the issue. I notice when you set DHCP as the
first connection you get a handy "Alternate" configuration tab. Bummer
that there's not one for handling dual static IP's.

Thx. Netsh did the trick.

Seems like a bit of a stretch to expect end users to set up DHCP at
home just to accomodate windows peculiarities. <shrug> Seems like a
rewrite is in order for the IP properties pages.
