By default, MS SQL does not enable remote access after a clean install. To enable this:
- Launch Sql Server Configuration Manager
- Double click TCP/IP, in the Protocol tab under the General section, set the Enabled to Yes.
- In the IP Addresses tab, scroll to the button. In the IPAll section assign the port to TCP Port. To use MS SQL default port, assign it to 1433.
- Finally, remember to set the firewall to allow the incoming TCP connection.
