I'm having a problem adding a CNAME using the DNS manager.
If I attempt to add a CNAME using DNS Manager I get a message:-
There is already an A Record entry for this host in this zone
I have checked that the recycle bins are empty. Both in DNS manager and ISP Manager.
I've also check the zone file and there is no A record or CNAME for the host I'm trying to add the CNAME for.
The site www.mydomain.com had been created with a co-domain mydomain.com.
That all worked fine
However, the client moved the site to an new host. But wished to stay with the ISPconfig system for Mail.
When the client moved to the other host I believe the reseller simply went in to DNS Manger and changed the IP address for www but made no changes to the configuration of the ISP manager side of things.
Now the client wishes to change the www from an A record to a CNAME.
I looked at what was there and changed the ISP Manager entry from www to web and saved it. That looked to me to have work correctly. That is the symlink from /PATHTO-WEB/www.maydomain.com to /PATHTO-WEB/webNN had been replaced by
Next I went to DNS manager and deleted the www A record. I emptied the recycle bin. When I attempted to add the CNAME I got the error. Back at the ISP manager I looked in the Co Domains and found an entry there for www so I deleted that too and emptied the recycle bin. However, I am still unable to add the CNAME.
I check in the zone file and there is no entry for www. So I'm puzzled as to why I can't add the www CNAME.
I looked in the database table "dns_a" but of course there are many www hosts so it's not easy for me to know if there is an entry for www.mydomain.com.
Can anyone advise me on the best way to investigate this further.
