Reducing NetBIOS noise in a 50-seat, 30-server organisation

view story

http://serverfault.com – We are a development shop where all 50-odd workstation computers run Windows 7 SP1 and most of our 20-30 servers are Server 2008 R2 or Server 2008 (there are a few scragglers still on Server 2003). We have a flat, single subnet environment where servers and workstations are in the same network. We have DNS servers with dynamic DNS registration enabled and currently we have WINS servers too. In performing some diagnostic Wireshark packet capturing on our network for an different issue, we've seen that there is quite a lot of NetBIOS broadcast noise on our network. We are looking to disable Net (HowTos)
