While I'm getting the hang of 2008, I've setup three servers for testing. I have a new SBS 2008 install with DNS and DHCP running. I'm having trouble with the DNS resolution from two other servers. One is running Windows 2008 Server R2 and the other is running Storage Server 2008. The servers are using the SBS for DNS. Web browsing is fine and DNS seems to work for the most part. The problem is that the servers cannot resolve any of the built in CNAMEs from the SBS server (connect, Sites, CompanyWeb, etc.). I have an XP workstation that is having no trouble with those records.
