Set FQDN of RDS server

all RDS roles are on the same server?
try to run powershell as an administrator and run  below command first

Import-Module RemoteDesktopServices

then try to run the command which you are trying to run to change FQDN.

Hi Gaurav.  I've tried that several times to no avail.  Yes all RDS roles are on this server.  Any other thoughts?

can you give the output of this : Get-RDClientAccessName

and also see if Set-RDClientAccessName works

Neither command works

Set-RDPublishedname : The term 'Set-RDPublishedname' is not recognized as the name of a cmdlet, function, script file,
or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and
try again.

+ Set-RDPublishedname
+ ~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Set-RDPublishedname:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Get-RDClientAccessName : The term 'Get-RDClientAccessName' is not recognized as the name of a cmdlet, function, script
file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct

well it seems like that you are missing something to get it fixed. Can you refer below link and see if that works for you.

Yes, I have tried this article with no luck.  I'm stumped as to why these command do not work.
