TCP/IP NetBIOS Helper Service


Enables support for NetBIOS over TCP/IP (NetBT) service and NetBIOS name resolution. Is used for resolving Fully Qualified Domain Name (FQDN) in Universal Naming Convention(UNC) for NetBios over Tcpip (NetBT) to find the actual physical address.

Note if using netbios to logon to the domain and this service is disabled, then the Group Policy will not be applied to the machine.

Note if wanting to change the location of the lmhosts file (Along with hosts, services, networks, protocols, NETRC files) then change this STRING registry value:

[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \Tcpip \Parameters]
DataBasePath = “C:\Etc”
