How do I unbind NetBIOS from TCI/IP?

I want to unbind NetBIOS from TCI/IP to increase security on my web server. To do this I go into: Network_Properties->Bindings->Show_Bingings_for_All_Services->NetBIOS-> and click Disable. Is this the proper way to?

I made the changes on one web server and it still works fine. However, on the second, after making the changes it can no longer browse the network or the internet. The servers are configured the same. Any ideas?

Thanks in advance
