- Plesk 12.5 for Windows
MSSQL Server could not start with error:
Server TCP provider failed to listen on [ 'any' <ipv6> 1433]. Tcp port is already in use.
The port of SQL Server is used by another process.
Check service uses SQL Server port with netstat (default port for SQL Server is 1433):
netstat -a -n -b
You see something like that:
Local Address Foreign Address State
0.0.0.0:1433 0.0.0.0:0 LISTENING
Stop mentioned service or change port to other one.
