16: FTP PassivePortRange invalid value
The IIS File Transfer Protocol (FTP) service enables the web server to be a FTP server.
Event 16 is generated when PassivePortRange has an invalid value.
How could you resolve this situation?
In passive mode, IIS 6.0 FTP randomly responds in a default port range of 1025 to 5000. The range can be decreased by specifying a value for PassivePortRange, which must be a value from 5001 to 65535. PassivePortRange can also be a specific value.
