Win9x network access works - XP doesnt

Hi,
I've just inherited a Win9x network, W95, W98 and WMe. I can access any
PC with the "C" Drive shared using my shared password.
On installing a new XP PC, I cannot set the "C" Drive to be shared as
in Win 9x. It only works if I set full read/write access with no
password so anyone can modify the files.
Can anyone help?
TIA
