Cannot find Host on Guest computer

The Problem

Instead of loading FrameReady from the Host computer, FileMaker cannot find the Host.

Check that an active Firewall is not blocking FileMaker Pro. See: How to Add Firewall Exceptions


  • Networking two or more computers to share FrameReady is accomplished by setting up a LAN (local area network).
  • FrameReady is installed on only one computer called the host.
  • All other computers on the LAN access the FrameReady files through FileMaker Pro and are known as guests.

There are two types of LAN configurations for networking FrameRead

Type One: Peer to Peer
  • FrameReady is installed and open on the host computer.
  • All guest computers access FrameReady by opening FileMaker Pro and opening FrameReady on the host.
  • Recommended when accessing FrameReady on two or three computers.
  • FileMaker is discontinuing Peer to Peer in 2020.
Type One: Client/Server
  • FrameReady is installed on the host computer along with FileMaker Server.
    • FileMaker Server opens and hosts the files in the background
    • FrameReady is not accessed or used on this computer.
  • All guest computers access FrameReady by opening FileMaker Pro and opening FrameReady on the host.
  • Recommended when accessing FrameReady on four or more computers.
Routers and Connections
  • All computers are connected to the network through a piece of hardware called a router. Check for router errors.
  • Connections can be wired or wireless, although wired connections are recommended whenever possible as it is faster and less susceptible to interference and poor signal quality sometimes experienced with wireless connections.

Things you can Check for Yourself

Although many factors can cause a guest to not be able to find the FrameReady files on the host, the most common hardware issues and software issues are addressed below:

Check for Hardware Issues
  • Check to see that all computers on the network can assess the internet.
    The most common network configuration is with a high-speed modem connecting to a router in which all computers are connected to; this allows all network stations to share the same internet connection.
  • If only one computer cannot access the internet, you know the problem is only with that particular device.
    It may be a loose or damaged cable, or a problem with the network card. Make sure the network cable is securely connected to the network card at the back of the computer as well as the corresponding port on the router. You may also try replacing that cable.
  • If all computers on the network cannot access the internet, try rebooting the router. This is done by unplugging the power to the router and plugging it back in.
  • When all computers on the network can access the internet, you can safely assume that they are all connected to the network.
Check for Software Issues
  • Confirm that the FrameReady files are being shared on the host computer.
  • If you are using FileMaker Server, ensure the files are open and the FileMaker Server service is running (refer to the FileMaker server manual for help).
  • In a peer-to-peer configuration, make sure FrameReady is open and the files are set to Multi User.

How to Set Files to Multi User

This is a level3 and level4 function only.

Setting Files to Multi-User on the Host

How to Open FrameReady on a Guest Computer

  1. Open FileMaker Pro, from the desktop shortcut or alias.
    If you do not have a shortcut, you can find the program in
    C:\Program Files\FileMaker\FileMaker Pro ##\FileMaker Pro.exe (Windows) or Macintosh HD\Applications\FileMaker Pro ##\FileMaker (Macintosh).
  2. Select the Hosts from the Launch Center.
    The host computer name should appear in the left pane.
  3. Single-click on the host.*
    Main Menu should appear in the right pane.
  4. Double-click Main Menu.
    You will be presented with an account and password dialog.
