WatchGuard Endpoint Security solutions incorporate tools to locate unprotected workstations and servers, and initiate a remote unattended installation from the management UI. Remote installation is only compatible with Windows platforms.

To use discovery and remote installation, make sure these requirements are met:

• UDP port 21226 and 137 must be open in the firewall for the system process.
• TCP port 445 must be open in the firewall for the system process.
• NetBIOS over TCP/IP and DNS resolution must be enabled in the network.
• Administrative shares required in destination computers (Admin$).
• UAC remote restrictions must be disabled.
• Domain administrator (DOMAIN\administrator) or local built-in administrator (MACHINENAME\Administrator) credentials are required.
• Remote administration in the destination computer must be enabled. Go to Control Panel > System and Security > System > Remote settings and make sure the option to allow remote connections is enabled.
• Turn on network discovery and file and printer sharing. Go to Control Panel > Network and Internet > Network and Sharing Center > Change advanced sharing settings and select Turn on network discovery and Turn on file and printer sharing.

Other considerations:

• Only broadcast domain (subnet) machines will be discovered.
• Discovery through various VLANs might generate erroneous information because of the presence of intermediate routers. We recommend you have a discovery computer for each VLAN that uses this feature.
• Windows Home versions do not have administrative shares enabled by default.

How Remote Discovery Works

This image shows how the discovery computer searches a network with subnets and evaluates whether to add a computer to the Undiscovered Computers list.
