How do you roll out patches over a network?

[cyborg]

Im a bit of a novice with networking sorry. Im working at a gaming cafe, and currently if there is an update to a game we have to run around and install the exe onto each machine seperatly.

Is there software so I can install it to all machines at once, or even a group at once?

40 pcs, all XP sp3.

Well the machines were all ghosted from a single harddrive, so each admin account is the same on them.

I can remote launch an application already on the machines with the cafe software we have, called smartlaunch, but I have two problems.
First problem is the tedious next > set directory > next > next > finish.
My second problem is an operating system limitation, as there is no proper 'server' here all we have is another xp machine were all the user files are stored and copied to their accounts on logon. Being xp this has the limiation of 10 connections at one time, which is really less when theres users in the store.

So I can tell 5 machines to execute an exe which is on a network drive (the 'server') but I still have to click the same buttons and set the same directory on each one.

Another question which is a bit seperate, how many connections can a NAS drive accept at any one time, can't see it in the descriptions.
