we want to play with sharepoint 2016 beta 2 and having a problem with the database (same server)
the system is 2012 R2 fully updated with sql 2012 SP2
sharepoint installed fine but during the configuration, it says it "can't connect to the database master...it might not exist or the current user does not have permission to connect to it."
firewall is disabled, all sql protocols are enabled and the application log states 'named pipes provider error 40 - could not open a connection to sql server'
i did do "sc query mssql$sharepoint" and it says it is running as well as the sqlbrowser. not sure what else to try.
