Usage scenarios

• When doing operation and maintenance, it is necessary to visit the operation and maintenance department for sharing under the user desktop environment, and it is difficult to switch users
• It is convenient to test the sharing permission settings of users back and forth

Remember to switch back to the original user identity after use, so as to avoid the user using your permission to share!

Basic principle

1. Use net use to disconnect existing users

net use * /del /y

2. Use the new account net use to share

REM Not necessarily used ipc$,You can use the existing path
net use \\share-server-ip\ipc$

3. Call explorer.exe to open the share

explorer \\share-server-ip
