Closed connections remain displayed in the Current connections window for time
specified in the program configuration (see chapter 6.5 ).
An error occurs when a packet from a connection is lost and the connection lost

tablished, if needed).
• *unknown* — name of service (if it is defined in Kerio Network Monitor — e.g. SMTP ,
HTTP , FTP etc.) or *unknown* (unknown service)

initiated. If the client has this information in its local DNS cache, the DNS query is not
sent and Kerio Network Monitor “sees” only the IP address of a destination server.
