Can not access the MAP NETWORK DRIVE in Windows 7

A week ago I want to Map Network Drive connection but can not, and it turns out there are several components that have not opened. For those of friends - friends who find it difficult and confused wondering here and there has been no answer, maybe I'm posting this time can help.

1. Open the Administrative Tools in the Control Panel in your Windows 7 (NOT the network drive server) 

2. Open the Local Security Policy 

3. Select the Security Option under Local Policies 

4. Choose Send LM & NTLM responses in Network security: LAN manager authentication level

If you are a user of Windows 7 Home Premium, here's how 

1. Click “Start” on lower left of screen.

2. Click “Run” in the menu.

3. Type regedit then click “Ok”.

4. User Account Control warning may pop up – click “Yes”

5. Find folder “HKEY_LOCAL_MACHINE” double click on it

6. Now on the same left side below the folder you clicked on find “SYSTEM” and double click on it.
7. Now on the same left side below the folder you clicked on find “CurretControlSet” and double click on it.

8. Now on the same left side below the folder you clicked on find “CONTROL” and double click on it.

9. Now on the same left side below the folder you clicked on find “Lsa” and RIGHT CLICK ON THE Lsa folder.

10. Scroll down to “New” then select “DWORD (32-bit) Value”

11. The new item appears to the right of the folders you have been clicking on. The name is highlighted as “New Value #1″ Change the name to LMCompatibilityLevel

12. Now RIGHT click on it “LMCompatibilityLevel” Then select “Modify”

13. Change the “Value data” from 0 to 1 then click “Ok”

14. At top right click on “File” then “Exit”

15. You are finished, and it should work.
