Non existing DNS zone

My DNS server keeps showing the following error in event log:

As you can see my actual domain is domain.za and NOT domain.sw. I went to HKLM\Software\Microsoft\Windows NT\CurrentVersion\DNS Server\Zones and found this 'ghost' zone there.

Is it safe for me to just delete this zone?

Was your domain renamed or is it in the process of being renamed? If it was renamed, was the process ever completed?

This happened a while ago, there domain.sw was removed (dcpromo) and a new domain was created.
Jeremy WeisingerSenior Network Consultant / EngineerCommented:
You can safely delete the zone then.
