Error Could establish connection to the database

Hi,

I encounter few errors when I try to create a login page using tool in Microsoft Visual Studio 2005, please refer to below :

'--------------------------

I create a Login screen from Toolbox.

When I try to configure the setting for Provider Configuration in the ASP.NET Website Administration Tool using Select a single provider for all site management data or Select a different provider for each feature (advanced) options, the error 'Could not establish a connection to the database' appear.

I have tried to run aspnet_regsql to configure the server and database and return to this tool to configure the Provider configuration but the same error 'Could not establish a connection to the database.' appear.

When I click the Security Configuration link in ASP.NET Configuration, the error as shown below appear :

'There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the below button to be redirected to a page where you can choose a new data store.

The following message may help in diagnosing the problem: An error has occured while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact under the default settings SQL Server does not allow remote connections.(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)'

When I try to choose Data Store in the Security Configuration screen(Figure 4), the same error('Could not establish a connection to the database') appear.

'--------------------

I also have tried to configure the SQL Server Surface Area Configuration but the same error still appear….

Is there any other configuration I need to set before I can create this login page?

Any advices or help is much appreciate.

Thank you.

Regards,

Vicky

Hi Vickie,

Based on the errors, have you verified that you can manually connect to the data source with the connection string information you are using? You can use the information at this link to see if the 'role manager' feature is enabled,http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag2/html/paght000013.asp. And, you can use this link to verify that your server will allow remote connections,http://support.microsoft.com/kb/265808/en-us. I hope this helps.
