    What is NTLMv2?

    NTLMv2 is an authentication protocol used by Microsoft Windows and Samba clients, the successor to NTLM and LM authentication schemes. It is far more secure than either of its predecessors, and under normal circumstances we would urge you to use only NTMLv2. However, some servers are not yet configured to exchange NTLMv2 information. If you apply the new University of Minnesota security policy template for Windows XP or 2000, your computer will refuse to connect to certain machines.
    For example, glycine.cbs.umn.edu is a Macintosh OS X Server version 10.3.x. This series of Macintosh OS X Server does not have support for NTLMv2. The newer version of the operating system, 10.4 does, but CBS is not yet ready to migrate to the new version. For people who need to connect to glycine, or other machines that do not support NTLMv2, you should allow your workstation to default to NTLM or LM if NTLMv2 is not available.
    Configuring your Network Security Settings

    The Microsoft Knowledge Base publishes many articles on how to configure your Windows workstations. It's a valuable resource, and one you should look to first when trying to find obscure information about the operating system. For example, the article Q239869 covers Enabling NTLMv2 on Windows 95, 98, and 98SE.
    This page covers how to set your Network Security settings on Windows XP Pro. The first step is to give yourself access to the administrative tools. Note that you must be an Administrator on your workstation to change these settings. To see the Administrative Tools, right click on your "Start" menu and select "Properties". You should see the "Task Bar and Start Menu Properties" window. Select the "Start Menu" tab and click on the "Customize" button.

    On "Customize Start Menu" dialog, click on the "Advanced" tab and scroll down to "System Administrative Tools" as shown. Select the "Display on the All Programs menu and the Start menu".
    < Resme gitmek için tıklayın >

    Now you can select the "Local Policy Settings" application from "Start-/Administrative Tools".

    Under the "Security Settings" tree on the left side of the application, choose "Local Policies" and then "Security Options". Scroll down on the right side to "Network Security: LAN Manager authentication level". Double click this option.

    Click on the drop down selection menu and choose "Send LM & NTLM - use NTLMv2 session security if negotiated"
    You're finished!
