I am using VMPlayer 12 to host Server 2012R2. Several of them. (Learning Server Administration). I have created the DC serverr and joined another server to the DC. At one time recently the servers could all ping the default gateway; I believe (because I didn't document it) the VMPlayer Network adapter setting was VMNet1 (host-only). Here is the results of IPConfig/all:

But now this server cannot ping the default gateway and the other servers cannot ping it. Any help like where to look to resolve this is greatly appreciated.
VMPlayer has several network adapter settings: Bridged, VMnet0 - VMNet19. The documentation, as much as I can find, seems to suggest Bridged works if you want the VMs to connect to the host adapter, which I do. I know that in the recent past this work just fine and now not. I just need some advice on where to look. I can't figure out how to diagnose it more deeply.
I changed the Network Adatper NAT; created a new VM. I started another VM also with the Adapter set to NAT. The new VM can ping the other one but not visa versa. TO me they seem identical in most respects.
