FM 12 server: Clients dropped
Filemaker server 12 running on a VM (Server 2008).
Clients are not configured to sleep. Disconnect when idle is inactive.
Security/Permissions have not been configured to disconnect.
I have run pings to and from server and client without any failures.
I have uninstalled antivirus.
Some clients continue to get dropped, sometimes while entering data! I'm getting error 51, "No longer responding; connection closed." It's happening on enough clients to know it's not a switch problem.
Please help me before I lose my mind.
