I went into PC Business Ed to check the configuration but I can't make heads or tails of the options. Much to my surprise I found that the single server being protected reported in the event logs that it didn't shut down gracefully. Microsoft EPMAP (End Point Mapper), also known as DCE/ RPC Locator service, used to remotely manage services including DHCP server, DNS server and WINS.Today the power failed and the batteries were exhausted.

They are used by system processes that provide widely used types of network services. The port numbers in the range from 0 to 1023 are the well-known ports. Multiple applications are known to use this port. Port is not registered with IANA for the application Port is registered with IANA for the application However, many unofficial uses of both well-known and registered port numbers occur in practice. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses. SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist. TCP and UDP port numbers are also used for the Stream Control Transmission Protocol (SCTP), and the Datagram Congestion Control Protocol (DCCP). This is why some even numbers in the well-known port number range are unassigned. As Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) were adopted, only one port was needed. Originally, these port numbers were used by the Network Control Program (NCP) and two ports were needed as transmission was done at half duplex. This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suitefor the establishment of host-to-host communications.
