I have a DNS entry for helpdesk.test.ez-ms.com that is an A record and it resolves to the correct address (same address as ezupgrade.test.ez-ms.com)
I have a VirtualHost setup with a ServerName of ezupgrade.test.ez-ms.com.
I thought I could just add a ServerAlias helpdesk.test.ez-ms.com to the above ServerName/VirtualHost and it would serve the requests for helpdesk.test.ez-ms.com.
However, when I do curl helpdesk.test.ez-ms.com I get Unknown HTTP_HOST (helpdesk.test.ez-ms.com). returned from httpd.
a curl ezupgrade.test.ez-ms.com returns the correct result for running index.php with no parameters.
What am I missing? I have restarted httpd and named but it doesn't seem to want to find index.php in the ServerName's home directory when addressed via helpdesk.test.ez-ms.com.
I'm sure I'm overlooking something simple! But sure can't see it.
