Re: Messenger service abuse (from inside the network)

[Jimi Thompson <jimit () myrealbox com>]

I'd also suggest going to management and having them issue a policy with 
as many teeth as possible, preferably advocating firing the offender.  
Have HR make everyone read and sign.  First violator gets smacked as 
hard as possible, again perferably fired.  That should get the rest of 
them in line.  Unfortunately, it's illegal to physically abuse id10T end 
users.  Sounds draconian, but if they are creating a DOS situation on 
their own network, they aren't undeserving.

2 cents,

Jimi
