I haven't had a chance yet to play around with SQL Server Express but I imagine it's similar to SQL Server 2000. With the latter, broadly speaking you need to:

- configure SQL Server to allow remote connections via TCP/IP

- if the machine the DB server is running on is also running a firewall (e.g. XP, Server 2003) that firewall also needs to be configured to allow incoming connections. By default it's port 1433, but this can be changed at both ends for added security
