Unable to map to a shared drive of a clustered server's CNAME DNS entry.

I have a Windows 2008 clustered server PRDADSALES which has a shared folder SALES.  I am creating a DNS CNAME entry of MPRDADSALES to point to that server.  

I am not able to map to \\MPRDADSALES\SALES from a Windows 7 PC.

Please advise if you know the additional steps to make the above works.

Many thanks.

You need to perform the below mentioned to access via CNAME

1. First  DisableStrictNameChecking registry entry on file server

2. Create SPN for File server

3. You need to restart the server after the changes

As mentioned, we have a clustered environment.

That method does not work on clustered setup.

As your environment is windows 2008 cluster then you can't use alias. This facility is available for windows 2012. Refer below mentioned article
