    <p>The core error from your screenshot is </p> <blockquote> <p>A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server</p> </blockquote> <p>unfortunatly, this is truncated. The message would normally then continue with " <em>is configured to allow remote connections.</em>", and this may further be followed by a specific reason (for example, it <em>may</em> state (amongst various other reasons) "provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified")</p> <p>However, with the message you have so far, it looks like a connectivity problem between the client machine and the SQL Server box. So I'd look at doing due-diligence against the SQL Server box and network connectivity first:</p> <ul> <li>The SQL Server server name can resolve</li> <li>That the server can be reached with ping</li> <li>That SQL server is configured to accept remote connections</li> <li>That the SQL Browser service is running on the SQL Server box</li> <li>That Windows Firewall isn't getting in the way </li> <li>That SQL Server itself is actually running in the first place</li> </ul> <p>If they pass then you need to validate than you can log-on. I'd normally use the SQL management tools, especially the command line tool <code>sqlcmd</code> to test basic connectivity (for example: <code>sqlcmd -E -S mysqlserver\instance</code> to connecto to the default database or <code>sqlcmd -E -S mysqlserver\instance -d database</code> to connect to a specific database). Obviously you'll need to run these as the user that your web application is running as, otherwise they'll attempt to authenticate as you (either use <code>runas</code> or start a command prompt under different credentials [find a command prompt in the start menu then, shift-right-click -> "Run as a different user].</p> <p>However what would ultimately help would be if you can get the full error message text (rather than the truncated version), then that may help narrow down the specific problem you're having.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
