Windows Server 2016 | Hyper V VM Network Adapter Issue

Hello, we have had an issue for the past week with our Hyper V virtual machines not receiving internet although being connected to an External Hyper Network Switch. Making sure they had internet, we tried switching the NIC correlated with the External Switch and have still had no luck. These systems are crucial to everyday company productivity so we are trying to avoid reinstalling Hyper V at risk of losing functionality with these VMs, an APP and SQL Server, both the VMs are running on Windows Server 2016 along with the domain controller.

The computers in the office are having no trouble connecting to the domain controller it is just when, because of the no network connection, they try and connect to these VMs they have no luck. We are getting a new server next week so any help quickly would be appreciated. Thanks!
