setting up file sharing problems

[Doubl3KiLL]

Hey, so Im setting up a network and I cant seem to get the computers to see each others shared drives. Also when I click on show my view workgroup computers it just hits an error telling me I dont have access and to contact my admin. Ive never run into that.

This IS however the first time that Ive used a netgear routers

So its 3 comps on a netgear router. Lemme know ASAP please?

Thanks
