Converged Network 2012 R2, host, VMs inaccessible

I'm just building a new server (HP 360 G7 with the latest firmware, drivers I can find) with 2012 R2.

I'm having strange problems with the network, it works, then it stops withouth me doing anything. I created a team (connected to an Extreme Networks switch that has these four ports in trunk mode, all 4 VLANs are available on these ports), virtual switch, virtual networks using these commands:

New-NetLBFOTeam –Name ConvergedNetTeam –TeamMembers pNIC-300,pNIC-301,pNIC-400,pNIC-401,pNIC-901 –TeamingMode SwitchIndependent –LoadBalancingAlgorithm Dynamic -confirm:$false
Set-NetLbfoTeamMember -Name pNIC-901 -Team ConvergedNetTeam -AdministrativeMode Standby
