GPO policy: "Configure NetBT Node Type" — controls how NetBIOS over TCP/IP resolves names. Registry: HKLM\SYSTEM\CurrentControlSet\Services\NetBT\Parameters:NodeType (REG_DWORD). CIS Benchmark recommends P-node (value 2) to eliminate broadcast-based NetBIOS name resolution, which can leak information on the local network segment. Reference: Configure NetBT Node Type
