win95 can’t see samba server

hi all,
i have installed linux 7.1 with samba server. on my network most of the win pcs can see this server in their neighbourhood but one m/c can’t. its settings are quite simmiar to other pcs with some differance mentioned below.

a) it usagenetware client 32 for connecting to netware server while others use microsoft’s netware client.
b) it uses gateway settings while others use proxy.

what are the things to checkup ?
