error 9611 cannot update domain data

[MarcoKraak]

When I try to add an domain I get this error:

Fail domain creation: Unable to update domain data: Unable to create the DNS zone for domain"dnsmng failed, dnsmng failed: Error 9611 at c:\program files\swsoft\plesk\admin\bin\dnscmd.exe ./ZoneDelete 1.168.192.in-addr.arpa /f: Invalid DNS-zonetype.

Hoever, the domain is created

What can I do about this?

Thnx,

Marco
