Map Home User in Windows 2003 Server

I want when an user in the lan log in in the server, in the user pc appears a map connection (for example disk Z:) who point in a share directory in the server. When the user save data in Z: the files are saved in the server. How can I obtain this? It's possible also with client Windows 98? Thanks. Sorry for my english!
