CNAME redirects in our internal W2k3 domain

I've inherited this setup and am trying to redirect our internal helpdesk's URL.

Here's what we have:

-Two Win2k3 DNS servers
-one A record for 'ServerA' (the primary name of one physical server)
-one A record for 'ServerB' (the secondary name of the same physical server as ServerA)
-URL to helpdesk: http://ServerB/reallylong/something/foo/blablabla.asp

What I'd like to do is make it so users can type http://helpdesk and get to http://ServerB/reallylong/something/foo/blablabla.asp

I created a CNAME entry that says helpdesk = http://ServerB/reallylong/something/foo/blablabla.asp

This doesn't work - it gives me the generic fail error in IE "Internet Explorer cannot display the webpage".

When I type http://ServerB/reallylong/something/foo/blablabla.asp in the browser, it goes right to the Helpdesk Web GUI.

Cname can be used to specify a hostname, domain, subdomain, etc. but not a full URL.  To do this, you need to:

CNAME helpdesk=ServerB
Change default page for SERVERB IIS to be /reallylong/something/foo/blablabla.asp
If there are multiple Webapps on serverB, assign a new ip to the helpdesk application

Thanks for the reply - I'll follow up with the helpdesk app vendor - they were the ones who directed me to the CNAME approach and told me *not* to muck with IIS.

You are probably right.  I'll circle back on this after I talk with them.

Still waiting to hear back from my vendor.  I haven't abandoned this.

Thanks
