Well it should be easy but 95 -> NTs tends to be quite tricky (to the point of not working????) Basically whoever logs into "Windows Networking" on the 95 machine needs to have *the same* username created on the NT domain and the Workgroup on the 95 machine needs to be the same as the domain name on the NT server.
Then create a share on the NT server with the user/group of the 95 user(s) given full access (no pw).
If you're using ODBC, it usually works best to map a network drive to the database directory and use that when specifying the DSN Target. Also you can better see where any problems lie - if you can create/change/delete files in the network directory you should be able to do all the DB functions.

That's only a start - 95/NT interoperability is a complete minefield!

HTH,
