Other than actually removing it from every workstation, and enforcing a
policy that the next one to load pointcast gets fired, consider getting
a pointcast server. Install it in your network, define what is business
relevant, use it to diseminate corporate info. What happens is that in
concert with pointcast, any requests from your address space get a redirect
statement back from pointcast that reconfigures the pointcast client to
point to your pointcast server. from then on, the client goes there.
Another choice if you are not running a web proxy is to do ip filtering
in your router to block access to pointcast. If you are running a proxy,
then the proxy can also do host blocking to pointcast address space.
When the pointcast server was first proposed here, I was rather leary, but
it seems to be working out well, especially as an internal bulletin board.
