Use the netstat command in the command line to determine which port is already being used. Check each port for the version of Spectrum that is installed.

For Unix/Linux servers, in the command line, enter: netstat -an | grep [port] .

For Windows servers: 
  1. Click Start > Run.
  2. Type cmd.
  3. Enter: netstat -aon | findstr [port] .
