"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you tried using a Legacy NIC in the setup of the  VM's setting.
Cliff GaliherCommented:
Why did you set DNS to 4.5 on all machines? Is your host also running DNS in addition to Hyper-V?? Besides the technical issues that causes, it also eliminates the 1+2 licensing benefits that standard provides. I suspect this is a big part of your issue.
BrendleAuthor Commented:
The host is active directory DC and DNS - it is 192.168.4.5 plus 2 vms

Running hyper-v on a DC breaks networking every time. There is no reliable fix. This just plain shouldn't be done. EVER.
