We have three computers and two servers in our company. Not all of them are visible in the SBS 2011 Dashboard.
The only visible computers are the ones who joined the domain using the http://server/connect site. But the Windows Storage Server 2008 R2 installation couldn't use this site, and joined the domain using the Server Settings in it's dashboard. One of the Windows 7 clients is also missing as it joined the domain using it's system settings.
I found an answer to this at social.technet.microsoft.com. Apparently the computers were in the wrong OU. But all our computers were in there. I tried it anyway - I didn't have a "MyBusiness" and created it and also Computers and SBSComputers. It didn't help.
