Multihomed PC with DHCP and TCP/IP

[Tina]

Does anyone know how to set up a laptop to be multihomed
(multiple IP Configuration on one PC) I need a static IP
at work to connect to the company domain and DHCP at home
for a cable connection? I use Win2K SP4.

Sure, but that isn't the normal meaning of "multihomed" *** to network
engineers
(the context here).

It does however make sense as a term from the "user's perspective."

The simplest way is to upgrade to XP -- really since XP has an "alternative
configuration" which is designed specifically for this purpose.

Presuming that isn't possible, you would need to manually reconfigure or use
a script -- netsh.exe is the scriptable program of choice but VERY tedious,
even difficult to learn to use.

The easiest way to learn NetSh.exe is to use it's export command to export
the settings when they are correct at each location (separately) and then
use
those (or edit them down) to reload whenever you return to the corresponding
location.

***BTW, the normal meaning of "multihomed" is a machine with "two or more
NICs
on separate network segments" -- some people use the term also for a
machine
with multiple IP addresses even if they are on the same segment/subnet but
experienced
network engineers seldom intend this meaning by the term.

Thanks Herb. I was told it was possible by the Cable
Internet Company, but they would not tell me how. Not
part of the support program. Great to know I don't have
to waste any more time on this one.

There is absoulutely no need to upgrade to XP just to
perform this. There is a very neat product called
MultiNetwork Manager that does this and a lot more that
you need when switching between networks
I have used this product for years and I can't live
without it, even as I am on XP! you will find it at
