One step I've always had to do is to enable Remote Volume Management. I could probably do this in AD, but old habits die hard.
I went into "netsh advfirewall" on the new server and it gave me a message:
In future versions of Windows, Microsoft might remove the Netsh functionality
for Windows Firewall with Advanced Security.
Microsoft recommends that you transition to Windows PowerShell if you currently
use netsh to configure and manage Windows Firewall with Advanced Security.
Type Get-Command -Module NetSecurity at the Windows PowerShell prompt to view
a list of commands to manage Windows Firewall with Advanced Security.
Visit http://go.microsoft.com/fwlink/?LinkId=217627 for additional information
about PowerShell commands for Windows Firewall with Advanced Security.
Certainly, there must be a way to do this with PowerShell.
My translation of the trusty:
netsh firewall advfirewall set rule group="Remote Volume Management" new enable=yes
Is the following:
Get-NetFirewallRule -DisplayGroup "Remote Volume Management" | Set-NetFirewallRule -Enabled True
