Description of the issue

Hello Experts,
I have a client server set up and the clients are disconnecting randomly from database with the error on clients as "Communication with the host was interrupted". There are 12 users in total.
I checked the power options and set them not to go in sleep mode , screensaver disabled , NIC is on IPV4, network cable is healthy and no issues are there. Ping request is also not showing any network packet loss. Also checked that there is no idle time set for clients to disconnect in Filemaker server 11 console as well as in File\Security\.
Cleaned the junk files from system, exceptions are also added in firewall and antivirus for .exe and .fp7 file types.
It disconnects during any time of the day and is really frustrating.
Any permanent fix for this issue will be really appreciated.

Thanks in advance.

Regards,
Alex
