Hi, 1.Widnows saves users' passwords in 3 files: • Windows System32 Config SAM file (without extension). • Windows System32 Config SAM.sav: it is a copy of the first one • Windows System32 Config SAM.log A transaction log of changes. If you open the file, you'll see lines similar to below: admin:1006:NO PASSWORD*********************:44bf0244f032ca8baaddda0fa9328bf8::: This means the admin account's NTLM password is '44bf0244f032ca8baaddda0fa9328bf8'. If you see something like: admin:1006:37035b1c4ae2b0c54a15db05d307b01b:44bf0244f032ca8baaddda0fa9328bf8::: This means the PC has LM hashes enabled. In this case, the LM hash is '37035b1c4ae2b0c54a15db05d307b01b'.

LM hashes are easy to crack, they have the strength of a 7 character password (look it up on wikipedia to find out why). 2.Basically, LM is used for compatibility with older clients. Specifically, Windows 98 and below. If you do not have any older clients on the network, then the cause for both hashes is most likely due to the password length being shorter than 15 characters.It is advised to disable LM hashes as the protocol is severely broken.

Hi Cartman I have found domain group policy setting applied to user PCs Setting which has been selected into group policy is settings-2 which is below Send LM & NTLM - use NTLMv2 session security if negotiated Clients use LM and NTLM authentication, and use NTLMv2 session security if the server supports it.

Due to abuse, the cracker has been closed to the public. We tried, we really did. Offsec students will find the priority code in their Control Panel. Enter your Hash and click submit below. All entered hashes should be 32 bytes in length! Before submitting a hash, check out our current table hashset! If you have both the LM and.

Domain controllers accept LM, NTLM, and NTLMv2 authentication. Recommended setting to apply via group policy is settings-4 Send NTLMv2 response only/refuse LM Clients use NTLMv2 authentication only and use NTLMv2 session security if the server supports it. Domain controllers refuse LM and accept only NTLM and NTLMv2 authentication. I have gone through MS KB details If I change the settings to 4 What is the possible issues client/users can have after change Muhammad Mehdi. Hi, In Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, the default is Send NTLMv2 response only.

In Windows 2000, Windows Server 2003, and Windows XP, client computers are configured by default to send LM and NTLM authentication responses. For more information about how to enable NTLMv2 on older versions of the Windows operating system, see in the Microsoft Knowledge Base. Windows NT 4.0 requires Service Pack 4 (SP4) to support NTLMv2, and Windows 95 and Windows 98 need the directory service client installed to support NTLMv2.
