Question

Hello colleagues

How enable NetBIOS in Windows 7 and XP on all network adapters via CMD? I khow about disable it:

wmic nicconfig where (TcpipNetbiosOptions!=Null and TcpipNetbiosOptions!=2) call SetTcpipNetbios 2

but I can't enable via CMD, ...call SetTcpipNetbios 0 - doesn't work (NetBIOS not changed in TCP/IP of network adapter)

Hi,

Use the commend line below to get a list of interfaces:
wmic nicconfig get caption,index,TcpipNetbiosOptions

Remember of the number of the interface which you want to change. use the commend below to change the setting of NetBIOS:
wmic nicconfig where index= [index number] call SetTcpipNetbios [state option]

state options:
0 – Use NetBIOS setting from the DHCP server
1 – Enable NetBIOS over TCP/IP
2 – Disable NetBIOS over TCP/IP

Hi,

Or, you may configure settings of NetBIOS over TCP/IP by using DHCP server options(0x1 as enable). Reference link:

But this is only work for DHCP enabled client, and each client also need to be set with related option.

ok, I can't use it via Group Policy because I don't know about index numbers on every PC in domain. Sure I can write 40 lines with 0-39 index numbers in the script but maybe passibly another way.

Hi!

I know this is an old thread but just in case anyone else needs it, here are a couple of one-liners to do what you want. The first one will set all NICs to disable NetBIOS over TCP/IP, even if they're set to use DHCP settings:

wmic nicconfig where (TcpipNetBiosOptions!=Null and TcpipNetBiosOptions!=2) call SetTcpipNetbios 2

This one only changes those NICs that have NBT explicitly enabled and disable it:

wmic nicconfig where TcpipNetBiosOptions=1 call SetTcpipNetbios 2

Hope that helps someone.

Cheers,
