Can't Delete Domain

I can't delete domain name through HELM. If you face any error with HELM, you need to look into HELM error Log folder at C:Program FilesWebHost AutomationHelmLogsError

The error log says it could not delete domain. So i checked the IIS (inetmgr) could not find the domain. But domain is present in DNS, Mail Server, even in c:domains folder.

The problem is solved by creating the domain manually in IIS, then deleted the web site through HELM, this time, site got deleted.
