Hi,
My client is using my SQL Sever application, sever installed on one of his local computers, dbs are being accessed using

connectionString="Data Source=Office1-MAIN-PC\EziBilling;Initial Catalog=dbBilling;User ID=sa"

By now everything is fine, now he demands to access the databases attached to local server, through internet too.
I am planning to create a client application that could connect to the server instance over internet. BUT I do not know what connection string I should use.

Also, how can I get the IP address of the server (do not have static IP)?

Thanks

Hi,

Configure Server instance via SQL Server Configuration Manager to allow TCP/IP Protocols.
SQL Server Network Configuration > Protocol for [InstanceName] > Enable

You could use a Dynamic DNS Service to resolve the IP of the server.

Ensure you open up port 1433 on your Server firewall to allow incoming connections.

Connection string to be used:

C#

connectionString=@"Data Source=\\ServerIPAddress\EziBilling;Initial Catalog=dbBilling;User ID=sa; Password=SomethingVerySecure"

Notes: Please ensure your sa account password is very secure, if you open up SQL server to the internet.

Hope this helps...
