You may receive the below error message while removing https binding for domain in IIS.
Solution: If you remove the https binding for the site through IIS then the SSL certificate will also be removed for another domain to which the certificate is assigned.
The only way is to remove the SSL bindings from the applicationhost.config file.
# Login to the server through RDP.
# Go to path C:/windows/system32/inetsrv/config
# Open the applicationhost.config file
# Search for domain SSL binding which you want to remove.
# Delete that complete line of the SSL binding and save the file.
You will see that the SSL binding for the domain has been removed without affecting other domains.
Note: Make sure you take the backup of the applicationhost.config file before making changes
