Block internet radio and MSN messenger.

Is it possible to block internet radio spooling, so that everyone doesn't
hammer it all day long with background musak??


How about Windows Live Messenger (MSN Messenger)? I read this just uses port
80 if it can't connect otherwise, making it very difficult to block. Any
ideas on this one?



I'm not trying to spoil people's fun, it's just that they whinge about slow
internet, while listening to four or five different radio channels at the
same time on a 512K broadband.

Thanks,

Martin,

An application-inspection firewall will block these services. For
example, SonicWall firewalls have the Intrusion Prevention Service,
which inspects the data and will block the traffic if it recognizes it
as IM (for example). Very configurable and easy to use.

Yours,
Brad Dinerman

What type of firewall are you using?

The better solution for Live Messenger is to block it on the
application level via Group Policy (i.e., don't allow the live
messenger executable to run on the machines).
