You need a server to provide network shares under multiple hostnames. For example, you are decommissioning a file server and need to continue providing those shares under the original UNC path though they are now hosted on a different machine.
- Make sure that there is a DNS entry for the alias that points to the file server , either by updating DNS to point that hostname to the new servers IP or moving the old server’s address to the new server as an alternate.
- Open a cmd prompt (or PowerShell terminal) on the new server.
- Use setspn to add the alias. Assuming you are adding an alias “old-server” to the machine “existing-server”:
- setspn -A “host/old-server” existing-server
- setspn -A “host/old-server.your-domain.local” existing-server
- Test the shares; you should now be able to access them with both the “old-server” and “existing-server” names.
If you have any older clients (Xp, 2003, 2000, etc.), you may need to update the registry on those clients
