Visual Studio .NET 2005 WebParts can't connect to SQL Server 2005

Hi All

I'm having problems creating WebParts in Visual Studio .NET 2005 with
SQL
Server 2005. I'm using Windows XP with Service Pack 2.

I've created a new web application and placed one WebPartManager
control on
the page and no other controls. Then I ran the application but
received the
following error message:

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

Description: An unhandled exception occurred during the execution of
the
current web request. Please review the stack trace for more
information about
the error and where it originated in the code.

SQLExpress database file auto-creation error:

The connection string specifies a local Sql Server Express instance
using a
database location within the applications App_Data directory. The
provider
attempted to automatically create the application services database
because
the provider determined that the database does not exist. The
following
configuration requirements are necessary to successfully check for
existence
of the application services database and automatically create the
application
services database:

If the applications App_Data directory does not already exist, the
web
server account must have read and write access to the applications
directory.
This is necessary because the web server account will automatically
create
the App_Data directory if it does not already exist.
If the applications App_Data directory already exists, the web server
account only requires read and write access to the applications
App_Data
directory. This is necessary because the web server account will
attempt to
verify that the Sql Server Express database already exists within the
applications App_Data directory. Revoking read access on the App_Data
directory from the web server account will prevent the provider from
correctly determining if the Sql Server Express database already
exists. This
will cause an error when the provider attempts to create a duplicate
of an
already existing database. Write access is required because the web
server
accounts credentials are used when creating the new database.
Sql Server Express must be installed on the machine.
The process identity for the web server account must have a local
user
profile. See the readme document for details on how to create a local
user
profile for both machine and domain accounts.

Hi

I think the problem is the fact that you didn't enable user instance
in the Sql Server 2005 Express instance

to do so run the following in the 'Query' window
------- Start T-SQL
exec sp_configure 'user instances enabled', 1
-------- End T-SQL
---------

Hi

then try to run first this

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regsql.exe

and "rediret" it to this Sql Server ( by default is searches for
".\SqlExpress" )

Hi

two more things

1. try for the test to stop the WinXP SP2 Firewall
2. take a look and see if the SqlServer-Agent is running , if not start it
3. I would re-run the "EXE"

and now try again
