new database in SQL Server

Cannot create a new database in SQL Server 2008 rc2. Says that it cannot connect to the server, instance-s开发者_开发知识库pecific or network-related error is displaying. Remote connection is enabled.

http://www.microsoft.com/express/Database/InstallOptions.aspx - needed the 3rd download option, problems fixed. Thanks

1. Is SQL Server running?

2. Is it on the same machine as your client?

3. If no to (1) & (2), then is there some firewall between the two, preventing traffic via port 1433?

4. If no to (3), then do your current user credentials have permissions to connect up to SQL Server?

What's the exact full error message? With all error codes? (Severity, State etc...)

It seems you cannot connect at all?

First check with the Sql configuration manager that the Sql server service is running.
