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.
