Thanks Jeremy!  Found this link that describes it in more detail:

We have alot of these clients that we don't control.  Bring your own 
laptop, where firewall is enabled by default, is prevalent here at the 
college.  I think disabling this server-side is more palatable than 
fixing every client.  I'm just concerned what functionality we'll lose 
in regards to point and print and printing in general.  Thoughts?
