• Confirm that the computer running the NDU has a network connection. See the section on
the NSA’s LAN connection for related information.
• The computer running the NDU can only discover NSAs in the same subnet. NSAs
connected to the same switch or router as your NDU computer are usually in the same
subnet unless the router is doing subnetting or the switch is implementing VLAN.
• The Memeo Autobackup program uses the same network port as the NDU to discover the
NSA. To avoid a port conflict, do not run the Memeo Autobackup program at the same
time as the NDU.
• Close the NDU and reopen it.
