ok i am puzzled right now....i have a web application connecting to a sql server database....i uninstalled sql server express and installed sql server 2005 full version...i changed the connection string in my application to be
Data Source=SKYBANDR62;Initial Catalog=aspnetdb;Integrated Security=True
and through the explorer bar i can access my database freely but when i run my application i get this error
Server Error in '/' Application. --------------------------------------------------------------------------------
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
but my connection sting is a sqlserver connection string not sqlserver express and what puzzles me is that on some pages is works and on others no
Asp.net will try to auto create a mdf file in the app_data directory if it cant get to the database server.
Try putting .\SKYBANDR62 in as the SKYBANDR62 is the instance name and the .\ means current computer. Dont know if this will help?
Also make sure you have changed all your connection strings to point at this new connection string ie the membership provider settings has an attribute telling it which connectionstring to use - make sure its not pointing at your old one.
Are you reading this from a web.config file?
Make sure the connstring is not declared elsewhere. Or maybe create one with a different name to test it.
