I'm trying to resolve a permission error on our sharepoint sql server. The login for the user that has failed is the WFE computer name on the farm config db. What permission or role can I grant that would target this?


SQL Database 'Farm_Config' on SQL Server instance 'SQLSERVER' not found. Additional error information from SQL Server is included below.

Cannot open database "Farm_Config" requested by the login. The login failed. Login failed for user 'DOMAIN\COMPUTERNAME$'.

  • can you share the error?

Can you check whether your IIS AppPools are running as Network Service or LocalSystem? If so - it's probably a good idea to change those and use a domain account instead of permissioning your Web Front Ends to access SharePoint Databases. See this thread for details.

Hope this helps!


I suggest trying to associate the permission error report to a cause or related symptom of a problem.

The Microsoft TechNet article on Event ID 3760, Alert Name:Database could not be accessed mentions a number of symptoms and resolutions for a similar error. Here is an excerpt:

Symptoms: The following symptoms might appear:

  • Content in the database is not available and attempts to access the database generate errors.
  • This event appears in the event log: Event ID: 3760 Description: SQL Database '' on SQL Server instance '' not found. Additional error information from SQL Server is included below.

Cause: One or more of the following might cause this:.

  • The SQL Server user login failed.
  • The database has been deleted or renamed.
  • The database is currently unavailable because it is in an offline or loading state.

Resolution: Verify that SQL Server is running

  • On the database server, in the Services snap-in, verify that the SQL Server (MSSQLSERVER) service is running.

Resolution: Verify that the user account can connect to SQL Server

  • Log onto Microsoft SQL Server Management Studio as the account provided in the error details and click Connect and then Database Engine. Type the server name provided in the error details and click Connect.

Resolution: Verify that the database exists

  • In Microsoft SQL Server Management Studio, expand the server node. Expand the Databases node.
