How can I install a package on multiple machines over the network.

I am wondering if there is a simple way to release a software install package to multiple machines on the same network. I dont want to connect remotely via an RDC, since it would take too long (+50 machines).
I am new to the networking world for macs, so any help really would be appreciated. Thanks

Oh i didnt know there was an app like that on a mac. for now i am running windows xp at work just because i want to get used to it again. ill boot up my mac now and look into that. is it come with the basic install?
thank you!
