Hi.

There are advantages and disadvantages to running a 
distributed architecture.

Running a distributed architecture can he beneficial 
because it offers your network fault-tolerance and 
higher performance.  Think about something such as a 
hard drive or power supply failure. If you have 
everything on the same box, your whole business is 
kaput.  If, say, only the mail server's HD goes tango 
uniform, the problem, while important, is not as 
critical as your DNS, mail and web servers all going 
down together.  You are also less likely to have all 
of your services in danger of cracker attacks if you 
have your services distributed with different passwords. 
You can even take this a step further by introducing 
multiple O/S and system platforms to thwart and confuse 
curious kiddies.  The down side is that you have more 
machines to administer (more time), it is more costly 
and it takes up more space than a single "do all" system.

Take care.
