CNAME Browsing

By Sean Ross ·
Hello,

I am trying to use CNAME for fault tolerance. If we loose a server and workstations are mapped to an alias we just bring the new server up and update the CNAME without having to remap workstations.

Scenario:

I have a server called corp.mydomain.com, I would like to use the alias corpserver.mydomain.com (corp.mydomain.com is a Winndows 2003 server).

When the CNAME is setup the alias corpserver.mydomain.com is pointing to corp.mydomain.com.

When I try to browse via \\, I get "Windows cannot find \\corpserver.mydomain.com, check the spelling..."

Is there some sort of group policy on corp.mydomain.com that I have to enable to allow alias browsing. Of course browsing directly to \\corp.mydomain.com works fine.

The big picture has to do with mapping XP workstations to a fault tolerant CNAME. And of course if you can not whack whack to it, you can not map it.

Any thoughts??

You will nto be able to accomplish this with Cname records which are aliases. You will need to set up a round robin DNS scheme using A records, where you entries would be like in the example below:

WindowsDC.mydomain.com. = 10.10.10.10
WindowsDC.mydomain.com. = 10.10.10.11
WindowsDC.mydomain.com. = 10.10.10.12

Added on as needed.

As a CName record can only exist in DNS to point at one entry, it is impossible to have a fault tolerant Cname.

"Run" the following command using your "cname":
net view \\cname
