Thankyou, Till.
But it is the creation of the other (sub)domains that is causing the initial problem.
I have tried both of the following scenarios without success:
----------------------
1.
Server: MyServer
Hostname: 123
Domain: abc.com
IP Address: 192.68...
Create DNS: Unchecked
Create DNS-MX: Unchecked
(Co-domains: empty)
2.
Server: MyServer
Hostname: www
Domain: 123.abc.com
IP Address: 192.68...
Create DNS: Checked
Create DNS-MX: Unchecked
(Co-domains: empty)
----------------------
What am I doing wrong? It is creating the actual subdomains (
www.123.abc.com, etc.) in the first place that is causing the problem.
Thankyou
HMK.
