Windows Server 2012 R2 to constantly loses network connection
hello!
i apologize for my bad english.
i installed windows server 2012 r2 with sql server 2014. in it, an erp was installed. windows is on machine with xenserver.
however, constantly lose connection with windows. users are using the system normally and then suddenly lose connection.
i try to ping from my client station and fails. after time (between 1 and 3 minutes) the connection back normal.
i was using bond on nic, but removed and left a unique card for network.
this server has ip 192.168.95.3/24. the ad server has ip 192.168.95.2/24. clients are in a 192.168.10.0/24 network. i use an hp 1910-48g switch with vlans. the port the server "95.3" connected is a trunk with all the vlans.
when lose the client connection server, do not lose to the ad server. the ad server is installed on same xenserver. and can ping between 95.2 and 95.3 (but imagine that is due to be in same xen server).
when lose the connection the server, access it physically (via xencenter) and he not ping toexternal addresses (microsoft.com) nor internal (192.168.10.3), only the 192.168.95.2.
i've tried many options but could not solve. at times the connection drops every 20 minutes (often comes almost be exact). at other times the connection drops hourly.
any help greatly appreciated.
right now, grateful for attention.

first, make sure server drivers, bios , firmware up-to-date - also, make sure windows is-up-to-date. in addition, try temporary uninstall/disable security software running on client / server , see if helps. equipment in between (firewall or network devices), please enable logging see if traffic getting dropped device.
as using xenserver virtualization, recommend asking them in citrix forums should more familiar product.
