I just installed SQL Express 2012 on a Windows Server 2008. I downloaded the advanced 64bit installation file and selected all the options except SSRS. Everything seemed to install successfully including SSMS. I was able to connect to the instance locally and create a database. However, when I tries to connect from a client PC, I got the "not configured for remote connections" error. I went into Configuration Manager on the server and saw that that SQL Browser was stopped. But the Start Service option was grayed out. How can I enable SQ
