We are building up our SBS 2008 R2 server and had in mind to put an SQL Server on the same box, same system. First uses of the system are a local file server, VPN for the same purpose, and a central database location. So far we are only a file server.
SBS 2008 (as noted elsewhere) WANTS to be the domain controller, so we turned off DHCP on our router. The system check performed before doing the SQL Server install complains about DHCP running on the same server. MS articles say that is for securtiy reasons.
So what kind of security danger would we risk, and what is the simplest way to keep everything happy?
