I'll recommend Red Gate's Multiscript product for that kind of thing.
If you can't get that (check the link at the top of this site), then a dynamic SQL script that queries sys.databases and runs the script you have against each one, is going to be easiest. You'll have to manually run that on each server, but it will get the job done.
Multiscript will be easier, and if you're administering multiple servers, it'll pay for itself pretty rapidly.
