Applying policies to whole school

[HomerSimpson]

We've been running AB Tutor for a little while now. One of the reasons we have bought it is for its ability to block websites, particularly cgi proxies which the students sometimes use.

Does anyone know if there is an easy way to apply the block policy to every computer in the school, regardless of whether it is currently off? At the moment we have to do it on a per-station basis and some tend to get missed because they aren't on/don't work at the time.

The other thing is the policies themselves worked on a couple of test stations, but many aren't working at all. Anyone else had that problem? Also if we add a new website to the policy how can you get it to update on all the stations?

Cheers for any help with this.
