Can't debug t-sql statement - could not connect to computer '.'

Question

When I was about to debug a T-SQL select statement, an error dialog popped up:

Unable to start T-SQL Debugging. Could not connect to computer '.'. This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server.

How can I start debugging?

Answer 1

You must connect to Management Studio with a server name rather than . or (local).

localhost also works.
