Domain – CNAME not working response 403 forbidden

cname-recorddomain

I have created the CNAME (test.mycompanyname.com) for one domain (test.example.com). We have just configured CNAME alone like below,

test.mycompanyname.com CNAME test.example.com

When we try to give "test.mycompanyname.com" in address bar, it will response 403 Forbidden error message.

How to resolve this problem?

Karthik.

Errorcode 403 stems from HTTP, not from DNS. This means that resolving your cname to an ip address of the original domain works fine, but the web server denies the request to view the page.

In your case most likely your http server is not configured properly to serve the request to test.mycompanyname.com domain name.

You should create a virtual host or add an alias name to one the existing sites.
