"The system cannot find the file specified"

I saw many questions on SO with this error. But none were related to forms. I just hosted my application server after testing locally. I think it worked for a few mins but I'm not sure as I may have looked at the localhost tab for a moment. Then it stopped working. I may have changed something as I was making changes on server too.

I checked my connection string and also tried logging into the DB using other ways and it is online. So, any clues what could be wrong. I don't think it is possible that sql server is only not responding to requests from an app and is available if you log in through SSMS.

Below is the error I get.

Server Error in '/' Application.

Someone also had this error and they said they were using the wrong store to connect to DB and hence the error. I only have one store in my code. There is no other.

Update:

I found the problem. It is membership related. Something is not right with my membership connection string. But I don't know what. My app requires registration so authentication is enabled. I left the default settings alone. Also published the mdf file in the App_Data folder. There is a similar question here: Deploying ASP.NET membership to Godaddy. But the solution is not clear and the answer is marked. I added the to the connection string and I see the error

The connection name 'LocalSqlServer' was not found in the applications configuration or the connection string is empty.

So, what should I do? This membership is working flawlessly locally.

Update:

I also tried what this one suggests Godaddy ASP.NET membership database woes. I removed the conn string and added with the name "LocalSqlServer" to make Godaddy happy. Then I removed and added the following with this connectionStringName - DefaultProfileProvider, DefaultMembershipProvider, DefaultRoleProvider and DefaultSessionProvider. Still get the same error of system cannot find the specified file.

People also ask

How do I fix the system Cannot find the file specified?

Use SFC to fix system cannot finds the file specified error. In Command Prompt, type the following command: “sfc /scannow”. Now press Enter. After scanning and correcting errors, restart the computer and check if the “system cannot find the file specified” error is fixed.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. text

Generally issues like this are related to any of the following need to be looked at:

  • firewall settings from the web server to the database server
  • connection string errors
  • enable the appropriate protocol pipes/ tcp-ip

Try connecting to sql server with sql management server on the system that sql server is installed on and work from there. Pay attention to information in the errorlogs.
