Remote login via modem

[Ivan Carey]

Hello,
I would like to be able to access my network remotely via modem access.

What I am trying to achieve is this. At the office I have a server, this 
server is Not connected to the Internet, I need to be able to Administer 
it from my Home office, so I am thinking that I need to access it via a 
serial modem.
What do I need to do to achieve this.

Thanks,
Ivan
