Mulitple IP configs - one for the Windows network gurus?

[Guest]

I have a laptop that I regularly take between two offices. At my main
office, I use a fixed IP address that allows me access to hosts within the
DMZ.

At the secondary office however, I cannot use that IP address, I instead
have to switch to standard DHCP to obtain an address.

What I want to know is, can i configure Windows with two different TCP/IP
configurations, that can be selected at startup?

I've seen the technote that tells me I can have an "alternate" IP config,
but that only kicks in when DHCP is unavailable. DHCP is available in my
primary office, I just don't want to use it.

I can't think of any way to have two different fixed IP addresses, can
anyone else?

Use the "netsh" command to set the configuration. Put the appropriate
commands in .bat files and run them as needed:

To specify a fixed IP address:

netsh interface ip set address <connection> static <ip> <mask>
<gateway> <gateway metric>

For example:

netsh interface ip set address "Local Area Connection" static
192.168.0.100 255.255.255.0 192.168.0.254 10

netsh interface ip set address "Wireless Network Connection" static
10.20.30.100 255.0.0.0 10.0.0.1 20

To specify a DHCP IP address:

netsh interface ip set address <connection> dhcp

For example:

netsh interface ip set address "Local Area Connection" dhcp
