win9x has subst, but is only substs local folders/drives... ie, it isn't connected to the network redirector.
If the win9x users aren't roaming, (are stuck on their 95 machines) then I'd only share those users home folders. It is a lot of overhead hosting a few hundred/thousands of home dirs on a server. as well as taking forever to explore to it, even if they are hidden.
Share the ones you need, and map deep for the clients you can, if you are able to.
I did have a batch file somewhere that would rmtshare a directory containing a list of folders as hidden shares assuming the the folder names matched the usernames and applied correct security and cacls to them... if any one cares.
