Hi everyone,

Please solve my problem,

When i connect remote desktop database using via SQL SERVER 2005 Management Studio,its working
But,when i connect via c# application its not working and the following error message displays:

 A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)

i am used following connnetion strings :

1) Data Source=IP_ADDRESS,3640\SQLEXPRESS;Initial Catalog=DB;Persist Security Info=True;User ID=sa;Password=XXXXX

2) Server=IP_ADDRESS; Database=DB; User ID=scbeacab1003; Password=XXXXX

3) Data Source=IP_ADDRESS,3640;Network Library=DBMSSOCN;Initial Catalog=DB;User ID=sa;Password=XXXXX

If you manually create an ODBC connection using those credentials, can you connect? If not, make sure your server name/ and or database names are correct.

Management Studio Connection which is working for you is local or remote ?

Are you connecting Management Studio from the same PC (using localhost) or Remote PC (using IP)?

Hi. My assumptions are:

1. While installing the the option for TCP/IP is not checked. or

2. You can allow the ip address of the local machine to the Remote machine by executing a query in the remote DB.
