Oh. You've just forgotten to make its DNS entry, that's all. Not an AD or RDP issue. Just needs normal DNS management.
Done...waiting on replication now. Now that I am thinking of it, most of our workstations have static IP's pointing to the current DNS server (also Domain Controller). After the new domain controller is promoted and the other one demoted, it is safe to change the IP on the new one to the old IP?
That's not a good process. I've done that and it is unnecessarily painful. Instead use DHCP to push out the new IP address as the primary and the old one as the secondary.
IN a sick way, I am OK with manually going to each PC on the night I do this to change the preferred DNS server address...that way, I can catch the PC's not on a static and make them static...it is also another way I can verify the migration worked and all PC's look good.

You want them to all be static? Why not DHCP?
-
Why not run the old system and the new side by side for a few weeks?

Again, my weak areas are showing. Networking...I've never configured DHCP.
-
Oh. You definitely want to do that. Not hard at all. And will make this kind of stuff much easier.
How many hosts on the network?
-
Hosts, as in HyperVisors?

Sorry, I mean devices with IP address. Like desktops, printers, etc.

About 50 workstations...several printers with IP's (not via print server)...SQL Server, two nas's...software firewall...

That is a lot to manage without DHCP but not horrible. Servers and NAS wouldn't be DHCP normally either way.

I am about to collate my notes and go talk to owners...I may put this off until next week. The recent DHCP discussion and the way the VM's are sluggish in a remote desktop session makes me a little nervous about how it will react in a real environment...I am about to test some things with a mapped drive to the services01 VM right now.
-
Got my "chill pill." Putting this off another week so I can test Unitrends, do some testing of our simple applications and procedures, try the DHCP things and flesh out my understanding of Hyper-V.
-
Good idea. You will feel much better.
Start with DHCP. Start rolling that out tomorrow.

You've been patient and a major help! Will update as I can and take advantage of this site!

Here's the slowness I've been talking about in my VM2 (File Server called services01)
This is only a 82 MEG file...taking FOREVER to copy to the drive on VM2:

That picture didn't seem to upload.

Looks like picture didn't attach well...basically showing 25 minutes to copy just 82 meg from my PC to the drive on VM2, that will eventually be our main file server drive. In addition, task manager shows 89% memory usage (of the 4GB allocated and on dynamic)...about to reboot the VM2 and see what happens but this is scary.

@garak0410 look at the tcp offload settings. I am not at a place to look at the client where I had the same problem. but there is a setting in hyper-v manager that I had to change then reboot everything in order get get the network to perform correctly.

image button uploads images to imgur. If you know the link you can edit the post to do it manually.
remove the extra whitespace I added to make it show

So I should turn off the TCP Checksum offload for IPv4 on both virtual adapters?
