Adding users to already http registered port by netsh cmd

See more:

ports

I am using the netsh command to add users to the registered port. As the port is registered, I am not able to add other users to it without deleting the port. So how can use netsh command in this case?

What I have tried:

I have tried using

Netsh http add urlacl url=http://+:80/ user=$env:USERDOMAIN\$env:USERNAME

but it gives error -

Url reservation add failed, Error: 183
Cannot create a file when that file already exists.
