wins configuration

l have windows Nt network – With One PDC and 3bdc
and 100 win95 PCs on the LAN. l having a problem mapping shares accross network. l have been told that win95 pCs cannot mapp across network and someone suggested l configure wins to allow this to happen. My question is can l configure the PDC to be wins server? or can use one of bdc to be a wins servr? Also are there any problems l should be aware off since this is a production environment?
