What type of WAN do you have? T1, DSL, VPN, ISDN? If it is reliable, you should not receive the error message. Besides network problems, when the computers are set to go to sleep, the connection to the FM databases can also be lost.
Just thought I'd chime in…
At our main location we access a couple of remotely hosted FM files via a site-to-site VPN. One location uses a 3.0 M T1 with one vendor and another uses 12 M cable access with another vendor. I've come to expect about 1 or 2 network interruptions per week, causing the database connection to be severed (which can be quite confusing since they are seldom used by regular users and they get the error message but all of their normal / locally hosted files are still up).
I can't answer your real question… I have no idea where to tweak such timeout settings for FM.
Thank you for your post. I can confirm that there are no settings to adjust the timeout on a connection to FileMaker Server.

Seems like this thread is suggesting several possible new features
- some kind of setting to control FileMaker's sensitivity to connectivity gaps
- a better, more user friendly response once the connection is lost
- a graceful way to regain a lost connection.
In my experience, VPNs are never as reliable as a direct connection. The additional overhead of encrypting the data, renewing the authentication & encryption settings, on top of a semi-reliable Internet connection makes for a less-than-ideal communication method.
Still, if FM were to implement option 1 and/or 3 as suggested by Phil, I'd be all for it.
Thanks for your comments.
Etripoli, we have direct 100Mb LES circuit between sites which are (touch wood!) reliable and stable. The only time they are used to the max is when we carry out overnite backups between offices.
I guess it just a problem we will have to live with.
I'm not familair with LES, it seems to be a UK product. At that speed, you have more of a LAN than a WAN, and I wouldn't expect any connectivity issues. Do you use routing or bridging/VLANs on that type of connection? Have you inspected the physical, data, and network layers for any issues? FM is only as good as the servers, computers, and network it is on. If there are issues in any of those components, you'll see problems - which begs the question, do any other applications have issues?
I'm having a similar problem, except no VPN, on a 1Gbs LAN & it only occurs on this one single brand new mac running "FileMaker Pro 11v3".
The Server is "Filemaker Server 11v2", & i have a mixed environment of Terminal Server 2003, Windows XP, & Mac OS X (all but this one client computer is running, "Filemaker Pro 11v2").
To make it worse the problem happens about 2-3 time a day, only on this one computer. Always in the afternoon, just after lunch, then mid afternoon & occasionally in the mornings.
The Only thing that has change is this computer was upgrade to a brand new machine, using the same ethernet port that the old one was on, (the old one didn't have this problem, & was running FMP11v2).
From the timing i would say there is something else happening like a flood of data on the network occurring at these recurring times, that has priority over FMS protocols. Except that it only happens to this one computer, & it didn't happen to the old one, plugged into the same ethernet port.
The Error Reads "Communications with the host was interrupted and could not be re-established. All affected windows will be closed." then the machine opens up the connect to remote host window & the user has to reopen there filemaker databases.
DefenistrateIt, you might want to keep Activity Monitor open all day on this problem workstation, with the tab at the bottom set to Network. If you're seeing connectivity problems occur during specific times of the day, you or your user can watch the graph to see if there are any spikes going on. If you want something a little less intrusive, try iStat menus—you can put a similar network status graph up in the menu bar.
