Disabling LM Hashing, Force NTLM

[digip]

In this article, it tells you how to disable the normal LM Hashing(stored for backwards compatability with Win95, 98, etc) http://support.microsoft.com/kb/299656

But what I was wondering, is it still possible to get the hash or crack it with something like Ophtcrack, Cain, etc. I just went in and disabled mine, just for the sake of making it a tad more secure, is it still futile since it is only storing it in NTLM vs LM hashes? Is there a way to use Kerberos in XP? Or is there a stronger alternative to the NT hash for XP?

Yes, it is possible to get the hash and crack it (f.e. rainbox tables), it just takes longer or is more power consuming.

As far as I know, it's not possible to change the algorithm except NTLM/LM.

But if you use a whole disk encryption software tool your pc is not vulnerable to live cds.
