As mentioned above you must have file and/or printer sharing enabled in the Network Control Panel, but you will also want to make sure that the NetBEUI protocol is installed and bound to your Win95 client's NIC. Another thing to consider is securitytype as set in the Access Control prop page. I am having this problem right now: Some Win95 pcs will not share properly to NT workstations when set to User-level ( get access denied error ), some Win95 pcs can't get the User list from the PDC at all. Share-level works fine all around but you have to set seperate passwords for Read-only and Full-access if you want any security at all...
Good Luck!
