Accessing a host over SMB using an alias name

The name has to be registered in WINS. Besides the server has to be told to accept requests with arbitrary names: http://www.winserverkb.com/Uwe/Forum.aspx/windows-2000-dns/3082/Server-alias

Update: After using this method for some time, I found out that this can have funny effects, like not being able to connect to a share from the same server. Therefore I would rather recommend using DFS namespaces.
