AOL Instant Messanger

Archived from groups: microsoft.public.win2000.group_policy (More info?)

Can somebody help me: What options can I use within the
Group policy Domain/Local that will allow me to block
AOL/MSN/Yahoo Instant Messangers. Thanks.

Couldn't you also just setup a Group Policy to not allow the execution of
said .exe ?

For example, set a GP to not allow yahoomsgr.exe or whatever it is , not to
run?
