A network-related or instance-specific error occurred while establishing a connection to SQL Server

By Santosh12:13 AMErrors and SolutionsNo comments

Things to check: 1. Make sure your database engine is configured to accept remote connections Start > All Programs > SQL Server 2005 > Configuration Tools > SQL Server Surface Area Configuration Click on Surface Area Configuration for Services and Connections Select the instance that is having a problem > Database Engine > Remote Connections Enable local and remote connections Restart instance 2. Check the SQL Server service account If you are not using a domain account as a service account (for example if you are using NETWORK SERVICE), you may want to switch this first before proceeding. 3. If you are using a named SQL Server instance, make sure you are using that instance name in your connection strings in your ASweb P.NET application Usually the format needed to specify the database server is machinename\instancename Check your connection string as well. Integrated Security=SSPI;Min Pool Size=5;Max Pool Size=60;Connect Timeout=30? providerName=System.Data.SqlClient/> 4.You may need to create an exception on the firewall for the SQL Server instance and port you are using Start > Run > Firewall.cpl Click on exceptions tab Add the sqlservr.exe (typically located in C:\Program Files (x86)\Microsoft SQL Server\MSSQL.x\MSSQL\Binn), and port (default is 1433) Check your connection string as well. 5. If you are using a named SQL Server instance, make sure you are using that instance name in your connection strings. 6. Check SQLBrowser; check that it is running. You may also need to create an exception in your firewall for SQLBrowser. 7. Check that you have connectivity to the SQL Server. Note what you are using to connect: machine name, domain name or IP address? Use this when checking connectivity. For example if you are using myserver Start > Run > cmd netstat -ano| findstr 1433 telnet myserver 1433 ping -a myserver

Please check your database user roles. It's necessary the database user to be owner. What you should instead do, is grant the user the following Roles: - aspnet_Membership_FullAccess - aspnet_Roles_FullAccess - etc. depending on what features you have enabled/installed into this database Do this by using Microsoft SQL Server Management Studio or Microsoft SQL Server Management Studio Express 1. Connect to the database you are working with 2. Open Databases 3. Open the database you are working with 4. Open Security 5. Open Users 6. Double-click the user who is accessing the database 7. In the list of Owned Schemas, check off the roles indicated above
