Simple but Tricky Question

[kolucoms6]

I have around 16 computers (P4) with One server(P4 with 3 GB RAM).

 

All are in LAN.

 

Each computer gets its own bandwith, through individual ADSL Router.

 

Now,

 

Where should I install where ?

 

I meant to say

 

Express Talk on all 16 machines and other applications ?

 

What should be installed on Server and what should we intsall on agent machine ?

[Guest nchto]

Axon should be on the server, and Express Talk should be installed on each PC, which would then register to the Axon server.
