hello, I'm trying to test the security of my network. Therefore I captured NTLM and NTLMv2 hashes from my network (with Cain&abel) and tried to crack them. The NTLM hashes were (easy) crackable, but the NTLMv2 hashes weren't.
so, my question is: is it possible to brute-force NTLMv2 hashes, and , if yes, with which program ?? (I've already tried L0phtcrack, without succes).

greetz, André.
