Microsoft Vista’s default security policy is to only use NTLMv2 authentication. I am not sure what the setting is by default in Windows 7 - so this may apply there too.
Note that NTLMv2 authentication is supported in Samba 3.0+
Seems like we ought to be heading towards Kerberos for all our authentication needs in the longer term.
