The “Expanded” checkbox just shifts the dialog box view to include FQDN items, so there is no PS equivalent because PowerShell allows any text that you supply.
But the script does have a -NamingMode switch so you can tell it to use FQDNs instead of NetBIOS names.

Thanks for this, although I can’t use the actual script, using it as a reference for my own script has been very helpful.

I found that in server 2016 the only way I could get it to work was to add the servers using the FQDN then tick the ‘Expand’, but I can’t work out how to do Expand via PowerShell. Could you point me in the right direction?

Thanks

To further improve the script, I would like the inclusion of “Microsoft Virtual Console Service” and “Hyper-V Replica Service”. I am too much of a noob to make this myself…

Did manually adding the NetBIOS names resolve your issue?

Unfortunately it did not work 100% for me as the netbios names were missing from the delegation.
