I look after an SBS2003 server and have a user that dials in via a 56k modem to access files. We've had a few problems with trojans etc and I suspect that its this user as he's bit of nightmare when it comes to computers.

Is there a way of firewalling a modem connection (TCP/IP filtering?) to prevent infections via ports?

Also can anybody point me in the direction of a definative list of required ports for a SBS network so that I can enable port filtering onthe server's NIC?

Thanks in advance!

Justin
