We recently built a new server that runs Hyper-V 2012R2 with 2 VMs. the 2 VMS being a DC and a SQL Server 2014. The server has two nics so it made sense to use the built in tools for NIC Teaming. Everything appears to be running great, however clients report connection loss intermittently to the SQL Server (runs a small ERP package), which kicks them off the system.
This was really never an issue on the older server, which has me to believe it's not the core network, but rather the server itself.
The settings for the Team were initially: Active/Active, Dynamic, Switch Independent (Standard options). I tried making the Active/Active team to go into Active/Standy... no luck. I also removed NIC02 from the Team which only left NIC01 in the team... no luck. I then even disabled NIC02...no luck.
I'm wondering if there is a design flaw in the server build or if this is a know problem for NIC teaming in software? I'm really at a loss on this one since it's so intermittent, but happens about every 1 or 2 hours for everyone.
