Windows10 cannot access the LAN folder

Recently, the hard disk can not store the data on the classmate's computer and then use the shared folder function provided by Windows to provide file access, but this morning I accidentally hung up the system and reinstalled the Windows10 professional workstation version.

Step.2 opens options in Group Policy

Keyboard Win+R, type gpedit.msc, and then select computer configuration → management template → network → Lanman workstation → to enable unsafe guest login, double-click to open, and then select enable.

Step.4.2

Keyboard Win+R, enter gpedit.msc, open the Group Policy Editor, and enable the following settings:
