I am using Novell DNS/DHCP Management Console.
When I delete a Zone:
[Z] Mycompany.com
=> @
=>email (A record)
=>www (A record)
=>web (A record)
=>proxy (A record)

@ : have 3 records
dns.mycompany.com (NS)
email.mycompany.com (CNAME)
email.mycompany.com (MX)

When I would like to re-add the resource record, I can't add
email.mycompany.com (CNAME)
It said : Error: EDNS312, A owner name can not have both CNAME and
other resource record.

What will I do now ? My email server doesn't work now. Can u help me as
soon as possible ? Thank you very much!
