Hi Rob,

Thank you for the posting. As you indicated you want to install the same
copy of Windows XP Pro on two computers of your home network.

To answer your question. This is not recommended. To do so, you need to
get "Microsoft Windows XP Additional License"

Home Edition $89.10
Professional Edition $189

Under the Windows XP End-User License Agreement (EULA), you may install one
licensed copy of Windows XP on one computer. If you need to install Windows
XP on more than one computer that you own, you may qualify to purchase up
to three (3) discounted additional licenses in one of the following ways.

Purchase Online
==============

To provide a better product experience for our customers and immediate
access to additional licenses, Microsoft has partnered with participating
online retailers in the U.S. to allow you to purchase and use a Windows XP
license from the convenience of your home or small business. Here¡¯s how:

1. Enter either your current Windows XP Product ID or Product Key in the
boxes below, and then click Submit.
2. You¡¯ll learn whether you qualify for an additional license as well as
which license you qualify for--the full version or version upgrade.
3. Purchase your Windows XP Additional License Product Key for an
additional license directly from a Microsoft-approved reseller. A Product
Key is an electronic number that "unlocks" Windows XP and allows it to run.
4. After you purchase a Product Key, the key will be displayed on your
screen and you'll receive a confirmation e-mail message that also contains
the key

Purchase at a Retail Store
=======================

Microsoft has offered retailers in the U.S. and Canada the ability to sell
additional licenses at a discount. If you own a licensed copy of Windows
XP, and want to buy an additional license in packaged form, check with your
local retailer.

Purchase via Telephone
======================

Microsoft also offers an additional license service to customers who have
legally installed Windows XP and have an immediate need for an additional
license due to work stoppage or other unforeseen circumstance. In the U.S.
and Canada, call the Windows Product Activation Call Center at 888-571-2048
for more information on how you can take advantage of this service.

Hope the above information and suggestion helps and answers your question.
If anything is unclear, please let me know.

Sincerely,

Cherry Qian
