CWP dosent seem to cope too well with one IP DNS
Firstly you got to get your names onto a Domain Registrar that allows using one DNS
Uniregistry - The Best Registrar in the world (I have 1750 names I have tried them all get a good deal with my affilate link)
http://ap.uniregistry.com/click?aid=966666dgwith CWP the Trick to running with One IP as DNS and not get the "is not a valid name" error is to manually edit the named.conf
DNS Functions/Edit DNS Config
Click Backup the file first, (Note the location it backs up to in case you got to copy it back)
and change
zone "myserver.mydomain.com" {type master;file "/var/named/myserver.mydomain.com.db";} ;
zone "myserver.mydomain.com" {type master;file "/var/named/myserver.mydomain.com.db";} ;
zone "" {type master;file "/var/named/.db";};
to a single line like
zone "myserver.mydomain.com" {type master;file "/var/named/myserver.mydomain.com.db";}
Save and Re-boot
To test this, following the re-boot, go back to DNS Functions, Edit Nameservers
you should see like
(It has made 2 of them the same)
myserver.mydomain.com 123.123.123.MyIP
myserver.mydomain.com 123.123.123.MyIP
If you just click Save Changes you will now see there is no Error Message
