The previous troubleshooting steps must be performed for each computer with BEST installed. Alternatively, you can check the general requirements for network discovery to work, as described hereinafter.
After installing each BEST, you might need to wait for about an hour before network discovery is performed and detected computers show up in Control Center.
If some computers have not been detected, check the following possible causes:
Computers directly connected to the Internet, but having no connection to the local network, will never be detected.
Computers in a workgroup or domain where BEST has not been installed yet will not be detected.
For full network visibility, BEST must be installed on at least one computer in each workgroup or domain in your network. Ideally, BEST should be installed on at least one computer in each subnetwork.
To detect computers in another domain, there must be a trust relationship between domains.
On the computers that have not been detected, make sure the following conditions are met:
Computer Browser service is started.
File sharing is enabled and allowed by the local firewall.
Network discovery is turned on (for Windows Vista or later).
NetBIOS over TCP/IP is enabled and allowed by the local firewall.
The Windows Internet Name Service (WINS) infrastructure must be set up and working properly across the entire network.
Computer Browser does not work over IPv6 networks. Computers using IPv6 addresses only will not be detected.
