  • Here id how you do it:



    You try to access a shared folder that is located on a Windows 2000 or Windows 98-based computer from a Windows 7-based computer. You are required to provide a username and password. However, the authentication fails. Therefore, you cannot access the shared folder.

    Note This issue does not occur if you access the shared folder from a Windows Vista or a Windows XP-based computer.


    Windows 7 uses NTLM version 2 (NTLMv2) authentication. By default, NTLMv2 authentication is not enabled in Windows 2000 or in Windows 98. Therefore, this issue occurs.


    Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

    To resolve this issue, enable NTLMv2 authentication on the Windows 2000- or the Windows 98-based computer. To do this, follow these steps:
    1. Start Registry Editor. To do this, click Start, click Run, type Regedit, and then press ENTER.
    2. Locate and then click following registry subkey:
    3. Locate the LmCompatibilityLevel registry value. 

      If the registry value is not present, follow these steps to create it:
      1. Select the registry subkey that is listed in step 2.
      2. On the Edit menu, point to New, and then click DWORD Value.
      3. Type LmCompatibilityLevel, and then press ENTER.
    4. Set the DWORD value to 1. To do this, click Modify on the Edit menu, type 1 in the Value data box, and then click OK.
    5. Exit Registry Editor, and then restart the computer.
