What should I do if I access the NAS/Samba server in win7?

            What is the NAS/Samba server? In fact, the two kinds of servers of this kind of computer, or generally they are used as servers, their main function is to achieve sharing between files. For those who often need to use sharing functions. Said to be a good tool. But recently, there is a user who uses win7 64-bit Ultimate to consult with us, saying that I don't know why, the NAS/Samba server in my win7 pure computer failed to access, so how do we solve this problem? ?
Fault analysis: Under normal circumstances, the win7 pure version of this situation is because the pure version only uses the NTLM v2 protocol authentication response message by default, and the current version of the NAS system and Samba only support LM or NTLM. So it will cause the access to fail. Below, let us introduce the solution:
1. First, let's press the win+r shortcut on the win7 pure keyboard to open the running window of the computer. After that, we enter regedit in the running window. Click Enter, this will open the registry editor window for win7 Ultimate.
2. In the open registry editor window, click on the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa in the left menu, then find the LmCompatibilityLevel option in the window on the right.
3. Double-click the edit window to open the LmCompatibilityLevel option, and then change the value data to 1.
