how can i block msn files transfer in firewall

anyone can teach , if i want to block or denny MSN FILES TRANSFER in my
office
how can i do ? which port i need to denny
i try to denny ( TCP¡G6891to6900), in msn 7.5 seem not work ?

pls teach me if u know
thank your very much

I understand that it can be done with a sophisticated filtering firewall
like Microsoft ISA 2004 per the link below but my guess is you are not using
ISA. Beyond that I don't know of a way other than disabling access to it all
together. You might want to post in the messenger newsgroup also. ---
