LimeWire Port: 6346
Emule Port : 4661

you can block these kind of softwares by not enabling all protocols in your main Internet Access Rule.
You can just enable HTTP&HTTPS , this will prevent these softwares from downloading any thing from the Internet.

About the MAC Address, It is not possible to block some MAC Addresses , you can block IPs instead.
You can block MAC Addresses from your network Switches.

the solution you give it to me is good but i have some issue using ISA firewall 2006 If I deploy your solution what port should I open for my Yahoo messenger, MSN, chikka, skype, and other softphone. because right now we are in the middle of desert here in Libya. I need to open for some reason to communicate using this softwares.

OR  can you give me firewall policy, like outbound and inbound access role to make this software work with out opening the all port on my ISA Server 2006

Ok, then create an access rule above the main Internet access rule that blocks these ports .
by the way I am also in Libya Desert.

Sir regarding this rule. at the button of my rule, all open rule  is like this:
Name of Rule:   All Open
Action: Allow
Protocols: All outbound traffic
From/Listener: All network ( and local Host )
To: External
Users: All User
From this rule all user are connected without any authentication, I would like also to make a authentication because I have 2 different Domain and this is the old setup here. some user they use netsetman to switch from the other network to connect to internet.  can you help me regarding this issue.  can you give me some possible rule that i can apply. Rregarding the Port i'll try to configure it now and thank you very much
For the authentication :
Change all users to (All Authenticated Users)
but first you have to join the ISA Server to the domain .
Also you have to maje trust relationship between the two domains to enable both domains users to authenticate.

The ISA Server is already domain member and should be the outcome if i'll change to (All Authenticated Users)?  but regarding the trust relationship between the two domains is the big issue because  they want this server separate due to some configuration installed and program inside to this server.
