Inorder to overcome this we change this security policy to meet our requirements.
Steps are as follows:
1. Run "secpol.msc" from the command prompt / Run utility in Windows. (Start->Run.)
2. It will display Microsoft Security Console for "Local Security Policy".
3. Select the "Local Policies" from the tree of "Security Setting" in the Left hand tab.
4. Select the "Security Options" from the tree of "Local Policies".
Security Settings->
Local Policies->
Security Options
5. Select the policy "Network Security: LAN Manager authentication level" from the list of policies in the right hand side.
6. Right click and open the "Properties".
7. Select the tab "Local Security Setting".
8. Change the drop down menu from "NTVLM2 responses only" to "LM and NTLM – use NTLMV2 session security if negotiated".
9. Apply and close the property window.
Now you can access network drives shared on Samba protocol.
Enjoy sharing.
