Hyper-V has matured into a robust and reliable HyperVisor and I have been using it reliably since the first iteration. With 2012 R2 the feature set makes it a no brainier when compared to ESX on purely cost basis.

Back to the original question regarding having a DC on the same box as the Hyper-V Hyper-visor and having it attached to the domain.

Two ways I can say I would set this up.

First way if I had access to only one Bare Metal box would be to leave the Hyper-V server off the domain and run it stand alone. This would remove the requirement of having the DC online before you login to the Hyper-V server and control functions.

Second way if I DID have access to another physical box would be to add a second domain controller as a second VM on a Second Hyper-V box. This way you almost always have a DC online to run creds against so you can attached the Hyper-V server to the domain.

Third way I have seen this setup is to have a completely separate domain for just the Hyper-V servers. I have only seen this in very large datacenter deployments so I don't really think this applies.

You are not leaving the modem off long enough to clear the ARP cache then... Give it a try and also unplug the coax cable to physically break the connect and leave it for 5 to 10 mins then reset the MAC to a new one and see if you get a different IP on a new Subnet... I bet if you do the internet performance is much better...

Sounds like NIC issues on the ESX host or the modem itself if this is happening again with a new VM...
You should not need to clone the MAC address you only need to power off the cable modem for 5 min or more to clear the ARP cache then a new IP will be assigned. If you are dynamic and trying to keep the same IP address for service reasons that might be your slow down and Comcast has put all the resources on the new subnet that will require you to get a new IP in order to interface with...

Disable the grace period check it will buy you more time if needed.

Did you update GPO to reflect the new server info?

@Hubtech PM me the Office 365 login and I will take a quick peek.

ok let us know

I have had delay to service issues with Office 365 in that you turn on a feature and it takes time to get all the permissions applied.
Other times I have just simply deleted and recreated the calendar a new and it worked.

Then as you mentioned you might consider a room mailbox...

Report back your findings

How did you create the calendar.. via powershell or in Outlook?

ok they released a V2 version that is fine

Dealing with a rabbit hole issue that ened up being a Windows patch KB3002657 breaks NTLM.

Uninstalling the patch fixes the issue

Silly question but have you tried running the installer by Right Clicking and Run As Administrator...?
I find that usually gets software that is failing on vague errors to complete.

.NET 1.0 it looks like so all the way back

they have a website section that is cheaper than a full server...
