This is a very good idea.  No matter what you might wish to happen, any
migration, be it to Vista, Mac, or Linux, will take much longer than you
plan.  Hofstadter's law will be in full effect.  It is generally best to do
it in short but solid steps, rather then blind leaps. since just about
everything in the migration can be done in gentle stages over a long period.
Don't set hard completion dates and try to keep the timing flexible.

Xandros is an unwise choice of distribution, unless it's purely being used as
a transitional stopgap measure.  The distribution's prospects are quite
bleak, and I would not want to bet my infrastructure on a company that has a
such a high chance of disappearing.

Most distributions lack good enterprise management tools.  It will take a long
while for your staff to figure out what works well for them, so any serious
rollout should not be set in stone until you get a comfortable setup.
Depending on what you plan on doing, Red Hat and Debian are probably worth
considering first.  (more on that below)

While getting full approval by the senior management is an absolute must, try
to get as many others on board as possible.  Explain that not everything will
be perfect, but after the rough spots are polished the effort will pay off in
spades.  Give the actual users an impression that they have a stake in it
too, and that it is for their benefit.  Ask them what they would really like
to see in the new system and keep their feedback in mind.  Also make sure all
of your techies are enthusiastic about this, since the migration will
probably require a lot of effort from them.  The more people who are hopeful
rather than sceptical, the easier this will be for you.

Obviously, the backend must be in place and working before the front end.
Another important aspect is file formats; try to roll out OpenOffice and
other cross-platform applications on the Windows machines before a move to
Linux.  Another options besides using a terminal service to run those old
windows applications is wine, or it's suit-clad sibling Crossover Office.  I
have had a great deal of success with both of these.

Depending on your setup, you may opt to go for the thin client approach or the
full-desktop approach.  For a desktop approach, use the
preseeding/auto-install capabilities available in most major distributions.
Set up your own local package repository and have your machines set to
upgrade from that automatically.  For a thin-client approach, I would
recommend LTSP (the Linux Terminal Server Project), which is the most
developed thin client setup available for Linux.  What approach you decide to
take depends on your existing infrastructure, the needs of your users, and
your plans for the future.

The first person to get onto the new system should be you, or whoever is in
charge of teaching the other techies.  Then the techies must all use it and
become familiar.  Consider a certification from the Linux Professional
Institute (ignore Linux+).  Once the techies are comfortable, hawk your new
setup to the few curious early adopters, and make sure you give them
something to take home to their own computer.  Talk with these people often
to assess their impression of the setup and make them feel appreciated.  The
next victims will be those who only use the most basic functionality of their
computer (web, mail, documents, etc).  They are relatively easy, since all
their needs are perfectly served by any platform.  The harder next step is to
migrate the more advanced users who may have special applications they are
fond of or have heavily customised their setup.  Make sure you meet with
these people _in person_ and help them through the process.  Many of these
types will not be pleased with the change (especially at first), and will
require significantly more backwards-compatibility labour.

Unfortunately, you cannot rely on too many people actively volunteering to
switch.  Humans are stubborn creatures and tend not to try new things.  Once
you exhaust your supply of volunteers, you have to start pushing.  Again,
take it slow, in particular with the more advanced users.  Don't expect to be
entirely rid of Windows for quite a long time, but keep pushing it ever
closer to the side.

Sometimes people just need Outlook, or MS Office, or Photoshop, etc.  Make
sure you allow them to continue using their existing tools if you don't have
an acceptable alternative.  Pushing too hard on these people will derail the
migration, so use kid gloves.  However, if there is a viable alternative to
the tool these people cling to, make sure you provide them with training and
hand-holding to make the switch.  They will become the aces in your sleeve.

1) Find the fire exit.
2) Run screaming.

I would not recommend Mac OS as an alternative to Windows.  It is seriously
lacking as a business platform.

Trying to find a distribution that mimics Windows is a losing game.  If users
expect the new setup to be just like Windows, then they will be annoyed every
time it differs.  Instead it is a far better idea to go for a system that
works well, is reliable, has a strong future outlook, follows the mainstream
of FOSS development.  Novell's products have been problematic in a number of
aspects, and their organisation shows a fundamental lack of understanding of
what they're actually doing.  Xandros and Linspire are niche products with
highly uncertain futures.  While many people get feisty about Ubuntu, I keep
running into problems with its quality and reliability whenever I try it.
Just like it is said that "nobody ever got fired for using IBM", the safest
pick for an enterprise rollout is still probably Red Hat.  They have
incredible experience with FOSS and much of what they develop gets used
throughout the Linux universe.  Being a Debian user myself, I would also
recommend Debian.  The Debian development process is overwhelmingly rigorous,
which results in a distribution of unparallelled stability and flexibility.
Commercial support for Debian can be obtained from a multitude of third
parties, whereas support for Red Hat would most likely come from Red Hat.
Both distributions are solid and capable, your choice would depend primarily
on your own personal preference and your organisational goals.

To recap, there are a few major points to permanently burn into your brain:
1.  Take it slow, do it right the first time.
2, Make sure you are ready _beforehand_, make sure your techies are ready.
3. Get agreement from as many people as you can.
4. Ask for help, chances are someone else knows how to do it.
5. Watch out for the advanced users.

Lastly, if things don't turn out well, or if the plan is scuttled before it
starts, don't sweat it.  FOSS isn't ready for everyone yet, so don't harm
your business or your career by forcing it if this turns out to be true for
your situation.
