So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.

Setting up a Windows 2019 Server for the first time
- Install the server - follow prompts.
- Setup the AVMA key as shown below OR use sconfig in the next step.
1 # Install the AVMA key.
2 slmgr /ipk TNK62-RXVTB-4P47B-2D623-4GF74

8 # Next we need to install Windows update and get it started.
9 # This will install nuget package too.
10 Install-Module PSWindowsUpdate

See the NAT setup near the bottom! That appears to have negated the need to change firewall rules. Also, I was not able to connect to the system via Server Manager right away. But a few minutes later, I could. No changes were made. But for posterity, they are here:
1 # To turn on or off the firewall
2 Get-NetFirewallProfile
3 # to set firewall on or off
4 Set-NetFirewallProfile -Name Domain,Public,Private -Enabled True
5
6 #Te get/set the firewall rule for private networks to allow any machine on a private network.
7 Get-NetFirewallRule | ? {$_.DisplayGroup -like "Windows Remote Management*" -and $_.Profile -like "*Private*"} | Get-NetFirewallAddressFilter #Shows the address filter
8 Get-NetFirewallRule | ? {$_.DisplayGroup -like "Windows Remote Management*" -and $_.Profile -like "*Private*"} | Set-NetFirewallRule -RemoteAddress 192.168.1.0/24

Power Shell Script to List Network Adapters on a VM
Note: When looking at the VirtualNetworkAdapterType value, "Emulated" means that it is "legacy" network adapter and "Synthetic" means its a non-legacy adapter.

This came up as a maintenance issue when we lost some VMs, but not the configurations
Change all VMs to use Dynamic Memory and reduce memory usage
1 $list = Get-SCVirtualMachine | ? { ($_.Name -like "*427*") -and ($_.DynamicMemoryEnabled -eq $False) }

3 if ($vm.Status -ne "PowerOff") {Stop-SCVirtualMachine -VM $vm}
