subdomain redirect not working

[gknowco]

Hi all,
I set up a subdomain of x on domain y.com, thus x.y.com, to redirect to y.com/x, which works fine. I then set up a subdomain of z to redirect to y.com/x, which doesn't work. So http://z.y.com gives a "server not found error." I compared the .htaccess files in both y and z directories and they're the same except for referencing their respective subdomains. Jaguar's not been able to help so far, telling me to clear my cache, etc. It did work, however, going through a proxy server, so I'm not sure why it doesn't work for me when i just type in http://z.y.com. Going to http://y.com/z gives me a 403 error, but that's probably b/c indexes aren't turned on for the site.

y.com's .htaccess:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^z.y.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.z.y.com$
RewriteRule ^(.*)$ http://y.com/x [R=301,L]

y.com's .htaccess? Shouldn't that be in the z.y.com folder (public_html/z)?

Perhaps the DNS entry for z.y.com didn't get created correctly. I had that problem sometimes on my old server--for whatever reason cPanel would stop talking to the DNS server, so whenever I tried to create a new (sub)domain it would look like it worked but without the DNS entry the name would never resolve.

If you haven't already, ask support to check that a DNS record for z.y.com actually exists.

You may also want to post the actual domain names in question so that others can test the connection. That way you can better determine if the problem is related to JPC or if it is on your end only.
