Hi all,
i'm using MSSQL Server 2005 Standart Edition.
i created ASP.NET application without MSSQL Server 2005 Express.
every time i Run my app always show these errors :

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:


1. 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.

2. 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.

3. Sql Server Express must be installed on the machine.

4. 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.


My questions is :
- if already installed MSSQL Server 2005 Std, should i installed MSSQL
Server 2005 Express too?
- i already changed my remote connections settings in SQL Server 2005
Surface Area Configuration to Local and Remote Connections and Using
Both TCP/IP and named pipes. What should i do??

Thx,
aCe
