Re: NT4 password limited to 14 characters ?

Here is what I did, just to be sure that it is the right method to disable LM hash :
On my PDC (NT4 Sp6a),

I have created a DWORD value (LMCompatibilityLevel) on HKEY_LOCAL_MACHINE\System\CurrentControlSet\control\LSA
with Value = 5 (Refuse LM and NTLM)

and

NtlmMinServerSec and NtlmMinClientSec (DWORD) on MSV1_0 with 0 as value.

Then I have restarted the PDC.

When I try to change the password from usrmgr, damewarent utilities or through a 2000 workstation, I always have an error saying that the password does not meet the password policy requirements but it's false :D

If I set "12345678901234" as password it works.
If I set "123456789012345" I have the message quoted above. (Same issue with a real complex password like IL0veLMH@shP@ssw0rd! )

This is quite strange because I have never really seen some people complaining about this limitation.

Thank you



OT but I must say: I like your style, George.

Try a more complex password like this:
aBcD1234.$#~9012@!-+789
