Virtual switch interferes with NIC

Hi

Windows Server 2016 Standard host. During adding hyper-v I chose to establish a virtual switch from the server's single NIC. After server is rebooted it turns out a number of features in the server's NIC are un-selected including IPV4. One effect is that server is inaccessible from outside.

My question is what is the problem here and what is the proper way to create a hyper-v to host Windows Server 2016 + Exchange 2016 so the hyper-v based setup (Windows Server + Exchange) gets good quality network connection?

Thanks

Regards
