The parent post's idea actually isn't that bad. If it's for an internal Windows-only network you've got the benefit that all computers have it installed already. It doesn't sound like the submitter needs anything fancy, so why go through all the trouble of downloading and installing another IM tool? This is what my company uses and it works great.
