| Retrieved from sqlmusings"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 instance2. 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 proceeding3. 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<connectionStrings><add name=”SampleConnectionString” connectionString=”Data Source=machinename\instancename;Initial Catalog=AdventureWorks;Integrated Security=SSPI;Min Pool Size=5;Max Pool Size=60;Connect Timeout=30? providerName=”System.Data.SqlClient”/></connectionStrings>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 well5. If you are using a named SQL Server instance, make sure you are using that instance name in your connection strings6. 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 myserverCheck what ports are IP addresses are being returned.Alternative:If you still can’t get any connection, you may want to create a SQL account on the server, a corresponding SQL user on the database in question, and just use this username/password combo in your web application."Where software development knowledge meets the reader |
