What is the big deal with using netbios

I have several clients that refuse to use netbios. My company’s product requires a network share to be configured to access certain files. There seems to be a panic about using netbios growing in IT departments across the country.

I have not seen a good reason for Netbios not to be configured on a network.

I also have not heard of an alternative to netbios when accessing shared folders on a network.

Does your company “ban” Netbios? If so, why?

How do you access shared folders without netbios?
