## Disallowing the Reserved Domains Transfer

To avoid DNS outages in Parallels Business Automation - Standard, you can forbid transferring reserved domains to Parallels Business Automation - Standard DNS.

For example, if the domain assigned to some widely-known mail server (like hotmail.com. aol.com., etc.) is transferred into Parallels Business Automation - Standard DNS (and such a domain is assigned to one of Containers), then all mail addressed to this domain will be sent inside this Container, but not to the right mail server.

Another illustrative example is transferring the domain assigned to your Management Node to Parallels Business Automation - Standard DNS. As a result, the Management Node domain name starts resolving incorrectly, and both Provider and Reseller Control Centers will become unavailable, as well as Control Panels.

To disallow transferring a domain in Parallels Business Automation - Standard DNS:

1. Open the Service Director submenu on the Navigation tree and select Domain Manager.
2. On the Domain Manager submenu select Setup. The Domain Manager settings appear on the screen.
