This article Reprinted from http://www.esoyu.com/article/html/5002.html

Many companies now use the Linux + SAMBA service as the file server. Some employees find that the file directories shared by Samba on the server cannot be viewed after the Vista system is changed, this is because Samba server only supports NTLM authentication, While Vista enforces NTLMv2 authentication. In this case, we need to use some settings to solve this problem.

The solution is as follows:

First, click [start] -- [run] And enter "secpol. msc" to open the management tool and expand "Local Policies ies )".

Then, click Security Options )". Double-click "Network Security: LAN Manager Authentication Level )"

Finally, click Send LM and NTLMv2 In the list. If the negotiation is completed, use the NTLMv2 protocol (LM and NTLM-use NTLMv2 session security if negotiated ).

With the preceding settings, the system automatically uses NTLM for verification when the other party does not support NTLMv2 authentication.

Type 2: Modify the Registry

Click Start, open the Run window, enter "Regedit" in the input column, open the HKEY_LOCAL_MACHINE--SYSTEM -- CurrentControlSet -- control -- LSA in order, set the value of lmcompatibilitylevel to 1.
