[Samba] nmblookup - windows 7 does not respond

[jcdole at free.fr]

Hello.

Laptop with windows 7 pro 32 bits (192.168.130.66) does not respond to nmblookup.

But from the Laptop with windows 7 (192.168.130.66), using explorer.exe I can browse the content of the public ressource on the serveur  //serveur-linux/publique
I have update the windows 7 registry but it does not help.
HKLM\SYSTEM\CCS\Services\LanmanWorkstation\Parameters
DWORD DomainCompatibilityMode 1
DWORD DNSNameResolutionRequired 0
