Ako skrotit agresivne okna - local master browser

Mame siet s cca 40 pc a servermi rozneho druhu. Uz roky sa o master brwserovanie stara linux so Sambou a drvivu vacsinu casu to chodi ako ma. Obcas vsak nastan problemy a pc je na sieti akosik pomenej a vtedy vidim, ze sa okna biju o lokalny master browsing. Vsetko riesim na dialku, takze neviem presne, co su to za PC, tipujem, ale, ze "novoprisle" s Win8, ktore nevedia kto je na lanke panom. V minulosti som toto riesili vypinanim pokusov stat sa local master brwserom v registroch, za posledne dni mi vsak vyskocili 3-4 PC, cp sa na sieti striedaju a nerozumiem preco.

Atd. AKo vidiet Samba sa musi neustale prekrikovat so zopar PC (momentalne su 3 aktivne) a bojovat o to kto bude sefovat sieti. Ako povedat tym blbym oknam nech pocuvaju, hlavne ked 90% PC vie posluchat a len necelych 10% si rebeluje?
