ok, im a little rusty i havent been a tech for a while (last job got messy) ok. Say your company is Test Company
root domain TC00 (good name, i dont think this will resulv anywhare heh)
Then have your new servers setup as bdcs based on location
TCCA00 (test company canada 00)
then you can have 99 canadain servers. You can also use diffrent country codes for more servers. This i find to work the best for a naming convention.
I think that answers your question. If it doesnt just repost and ill take another stab'at'er
