I use management studio to connect to the database engine. I type in the server name: "tcp:localhost\SQL2012" and I receive this error message: (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) This post by the SQL Server team seems to be really useful, in it they suggest testing out the SqlBrowser service using PortQry. When I do, I get this info: Querying target system called: localhost Attempting to resolve name to IP address... Name resolved to 127.0.0.1 querying... UDP port 1434 (ms-sql-m service): LISTENING or FILTERED Sending SQL Server query to UDP port 1434...

SQL Browser seems to be functioning and ports and firewalls seem to be open or irrelevant (I'm trying to connect to localhost).
