Unable to add/remove domain alias in Helm Control Panel

You could have experienced this error

CDomainAlias.DeleteEx 0-xxxxxxxxxx: Unknown error while adding host header: A name contained an invalid character.

in Helm Error Logs. If that’s the case please remove IIS.XML in the remote server where the domain is actually hosted.

P.S. IIS.XML is available at this location ‘C:\Helm.config’ (most commonly).
