Win7 system can not access the working group is how the matter

Working group is a computer joint created under the LAN, can access the common shared files, will bring convenience to work or multiple computers in the home, but win7 64-bit flagship The version appears to be unable to access the working group?
1, press the windows+R key of the win7 system, open the running window, enter [gpedit.msc] in the early, enter the group policy by entering;
2, group After the policy is opened, open the dialog box to expand the computer configuration, Windows settings, security settings, local policy, and then click the security option to find the network security: LAN Manager authentication level;
3, directly double-click to modify the verification level Send the LM and NTLM responses (&), then identify and open the Control Panel, Network, and Sharing Center to see if the public or working network is currently in use. If it is a public network, just click on the public network, modify it to a working network, and finally restart it.
This way you can revisit the win7 pure family group, which can be accessed, or shared into the family group is a lot easier!
