Further to the last post
There are a number of issues with NTLMv2 and legacy applications such as
Windows RAS that cause lower levels of authentication
I still say that Kerberos or IPsec based auth is the best policy in
windows. LanMan, NTLMv1 or V2 are vulnerable.
Precomputed tables may have been uncommon 12 months ago - but that was
then and this is now.

I'm not sure what you mean... NTLMv2 uses a single 128bit key for the
hash,
challenge and response... Or are you referring to the NTLM2 session
response key (56+56+16)? If so, that is not the same thing as NTLMv2...
Can
you elaborate please ?
