network problem

ok, i setup a network between my windows me pc and
another with 98,ME as host,had it working ,g/f's kids took
there pc back to there dad ,he tried putting another hard
drive in wouldnt work,so he put the original back in,since
it came back,i tried to setup the network again,using
network wizard on my ME based pc,when i run the floppy in
98 it says unknown has caused a error in unknown and will
now close,,,,,,,,, when i click ok it gives a new
screen,that says.....restricted.... this operation has
been cancelled due to restrictions in effect on this
computer.please contact network admin.....i got a prog.
that changed ownership records....didnt help...tried
unplugging and removing memory battery...didnt
help....anyone have any ideas about this and how to fix.
