Verify that TCP/IP networking software is properly configured on the host and client computers. Verify that the simultaneous client limit you specified has not been reached.

FileMaker Pro databases shared via TCP/IP can be opened remotely using the list of local hosts, the IP address of the host machine, or the DNS name of the host machine if one has been defined. For example, a database hosted from a computer with an IP address of 192.168.10.0, and a DNS name of host.domain.com can be opened by entering either the IP address or the DNS name in the File menu > Open Remote > Network File Path field, using the format fmnet:/192.168.10.0/<filename>. (Note that fmnet:/ uses a single slash.)

If no client computers can see FileMaker Server in the Open Remote File dialog box, check the server network connection, and make sure the FileMaker Server ports are open on any firewall.

If the master machine has a firewall enabled, then you must open the ports required by FileMaker Server to communicate with users and administrators. See Ports used by FileMaker Server.

Each shortcut starts Admin Console for a specific FileMaker Server deployment. If the IP address of the master machine has changed, you must remove the shortcut and start Admin Console from the FileMaker Server Admin Console page again. See Starting Admin Console.

The firewall settings on the master machine may be blocking the display of databases to clients. See Ports used by FileMaker Server for more information on which ports need to be unblocked in firewalls.
