Hyper v NIC Teaming and v Switch

I lost connection to a remote server and trying to see what happened.

I was setting and configuring this new server and started to play around with creating NIC team and v switch.

NIC ports on an intel add on card: 4
Onboard NIC Card: 2

Created NIC team 1: 1 onboard + 3 from Intel
Works great.

Now I wanted to assign a static IP to this new Hyper V server - 2012 R2 Std.

So I thought of doing some fault tolerance and created a second NIC team:
localserverNICTeam:  Onboard NIC1 + Intel NIC 1

Now I tried to assign a static IP addressing by doing following steps:
1. Created an External  vSwitch and selected the Multiplexer#2 for choosing the second nic team : localserverNICTeam
Checked the box that says - allow communication with management network.

2. Under control panels - network connections - RIght click on this vSwitch and assigned IP addressing as:
IP 10.11.3.10
proper subnet and gateway and dns servers.

I lost connection but after sometime the remote server came up.

Now the issue is I can RDP to this server from other computers but I cannot ping it. What could be the issue here ?
