In the Microsoft Article Q299656 “Removing the
NTLM Hashes from the AD & SAM”, states to remove
the LM hash from these you must create a registry
key.

 In the article the following steps are outlined.
Edit the following registry key:
        HKEY_LOCAL_MACHINE\System\CurrentC
ontrolSet\Control\Lsa
        Add new Key:
        Key Name: NoLMHash

Once the registry key is set, the LM hash for a user
account is not removed until the next time the user
changes his or her password. Therefore, in addition
to setting this key, we also need to ensure that all
users change their password.

The registry key is not removing the LM Hash from
the AD & SAM. This is the only key the article
Q299656 refers to on a W2K or Windows NT
machine.

Need the conclusion of the article there is a reference
to the XP systems, and you must enter the following
registry key and value.

In the article the following steps are outlined.
Edit the following registry key:
        HKEY_LOCAL_MACHINE\System\CurrentC
ontrolSet\Control\Lsa
        Add Value:
        Value name: NoLMHash
        Data Type: REG_DWORD
        Radix: Decimal
        Value Data: 1

Should there be a value set for the W2K and
Windows NT version? Is the value and registry key
the same. How do we remove the LMHash from the
AD & SAM. Please advise on the registry key we
need to enter.

Thank in advance for your time and effort!
