shell script related to server

I want to run a shell script in such a manner so that if i will run that script on one place than changes related to that will reflect on all the servers in which i want.Is it possible to write such kind of script?Please respond me as early as possble because it is very urgent for me.

You will need to be a lot more specific if you want to get help with this.

What do you want to do with the script, how many servers, how are the servers related to one another, do you use a naming service, do they have nfs mounts etc.

u might need to trigger a copy of the script on each of these servers using some network software....
