Windows XP laptop with Static and DHCP requirement

i have a windows xp pro laptop that I use primarily at my office. It has a
static IP assignment and connected to our SBS2k3 domain. However, I need to
be able to use it on the road. Unfortunately, when I return from a trip and
was using the DHCP settings of the location I connected to (primarily for
internet access), I am unable to connect back to my office. In fact, the
only way I am able to connect is to first turn on the laptop without the
network cable connected, then login with my cached acct then plug the cable
in. This seems to allow me to connect to the domain. Is there a proper way
to configure my laptop to allow me both the ability to use my sbs2k3 domain
access and also DHCP access on the road?

Assuming you want to setup one NIC with two IP addresses, one for static IP
and another one for DHCP, you can use alternative configuration. This how to
may help.

Hi - honestly, the first thing I'd do is ask the people who manage the SBS
domain, "Why on earth are we using static IPs on workstations, in 2008?"
That's just silly - there is no good reason to do it.

Workarounds are fine, sometimes (and Robert's reply will help), but the
situation you're attempting to work around strikes me as unneccessary in the
first place.
