Broken share paths with file server rename?

I am going to be re-building the office file server and in the process, rename it to conform to our new naming convention.

My question:

A rename of this file server will likely create numerous ‘broken-links’ for users who have 'hard-coded' mappings in file paths that reference the OLD server name.
Will a CNAME in DNS, such as 'OLDSERVERNAME’ pointing to the correct IP of  'NEWSERVERNAME', fix this type of issue?  

Also, looking for ANY potential exceptions, caveats, etc… (applications, static mappings, ..)

Thanks for your insight!

Yes, a CNAME (alias) record with the old name that points to the A (host) record with the new name will work.  Most applications will rely on name resolution for communication but some may be coded to use IP Address only so I'd make sure to give it the same static IP.  

Do you use WINS (or NBNS) in your environment?  That's the only potential exception I can see for a simple file/print server.

We do not use WINS on the network.  I hope to be able to test the alias tomorrow and report findings.  I am confident it will work but would like to see it...

If you just have a cname or host record pointing to a host with a different hostname, then you will not be able to map drives directly; you're likely to get an error 52 instead.
Check this article on how to map drives using an alias:
Connecting to SMB share on a Windows 2000-based computer or a Windows Server 2003-based computer may not work with an alias name

oBda, nice catch....I missed that one...

Davis, to test for this error add the cname entry to DNS and execute the following from the command-line of a client machine:

net view server.domain.com

If there is no error you should not have any trouble connecting via the cname entry.

Good Luck!
