Hi Pete,
The firewall have no issue. I even tried after i disable all firewall. and for the SQL Authentication, i suppose to use Windows authentication. This is similar like how i use in other servers.
If i still try with SQL Authentication, i will get below error:-
This error clearly show that my authentication is wrong. I've logged in to SQL server to check my Database name, and its all correct.
One thing i notice while browsing for solution, some ask me to check SEMSRV service. This not available in this newly installed PC after uninstall, but i notice i have the option in other servers.
