如何通过远程访问将应用程序连接到SQL Server 2008

Question

Is there any way to connect to the database which is at remote server using ASP.NET ? I checked for TCP/IP ports at remote desktop. They are also enabled I have tried specifying IP address and SQL Server name in the connection string but it shows the following error:

(provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

Thanks in advance

Answer 1

Must be change some configuration on Sql Server Configuration Manager

• Open Sql Server Configuration Manager And Select on tab SQL Server Network Connection
• Double click Protocols For ... Change to Enable YES
• Click IP Addresses tab and set IPAll TCP Port 1433

1433 is a default SQL Server Port. If you want to set another port , port must be unavailable and define port on Windows Firewall With Advanced Security
