Answer "yes" to replacing system files, and then right after it run the update for Windows 95 (and IE if you have it). I don't think that 95 had too many options to repair itself?
Many times, many ways. It's not an issue now (using new PC).
My story was just meant to illustrate that Win9x can develop problems with networking (and remote printers) which are seemingly insolvable by mere mortals in a reasonable period of time.
My particular problems have been resolved by using a newer PC - i.e. it wasn't worth fighting with any more. The cost in my time troubleshooting was more than the cost of buying and configuring a new machine.
