Why did some of my workstations disappear from the list?

If some of your workstations disappeared from the list of computers available for backup, try this:

• Make sure that Backup Network Workstation service is running on every PC. If it doesn’t, launch it.
• Make sure that Handy Backup Network Server, Backup Network Coordinator and Backup Network Workstation are in your firewall exceptions list. For proper work of Handy Backup Network Server, they must be able to communicate with each other.
