I've installed the server.
Next I've opened the firewall port 1433 and sql server network configuration made sure all IPs for the TCP pointed to 1433.
I made sure that the service starts automatically, rebooted and tried to go SQL Server Management Studio - but it does not let me neither with WIndows Authentication nor Sql Server authentication. The solutions I saw all involve being already in the studio.
The environment is a windows 7 professional standalone PC - there are no domains - it does belong to a workgroup
Help is appreciated
