Well, you can run it 3 times. When you install Windows 2008 without a key the 60 day trial will start, you can run the utility to add another 60 days to your trial period. You can use the utility for 3 times giving you a total of 240 days.
But in 240 days it will expire completely, so you would need to activate it with a proper key. You can read about it in KB article.
