SQLServer2005 Express problem
For a personal hobby project I wanted to try-out some new stuff and some O/R mappers. So I installed VS2005 and SQL2005 Express. I used VS2005 to create a database in SQL2005 this all worked fine. Then I wanted to tried LLBL Gen Pro and Entity Broker. But I could not connect to the database I created in SQL2005. I got an error the database could not be found or the connection was refused. I found it a bit strange because VS2005 had no problem in connecting and every other application had. After some intensive googeling I found the there are some problems with the shared memory protocol of SQL2005 Express. So if you enable TCP/IP and Named pipes and set TCP/IP as the default protocol everything seem to work fine.
