How to establish mapping with Net Use? (Specific situation is as follows) - China DOS Union Forum

I wrote a program in VC for local network files (all data is stored on that server) and local printing. Since it needs to access network files, in the open dialog box, it is necessary to access the network machine (you need to enter a username and password to enter that server), and then you can access the shared files of the computer. (At this time, an IPC$ connection should have been established, right?).

Since the file is on the network server (ACAD's plt file, which needs to be printed with copy *.plt prn, so I need to use DOS...), I need to use net use z: \\server\data to map the drive letter.

But every time it shows
A system error 1219 occurred.

The provided credentials conflict with the existing credentials set.

Then I changed the command to net use z: \\server\data "" /user:"administrator"
And it shows again
The syntax of this command is:

NET USE ]
username]
username]

| ]

NET USE {devicename | *} /HOME

NET USE

I'm dizzy... I don't know what to do.
Dear DX, please help me.

net use z: \\server\data /u:administrator "Enter your password"

May I ask:

I have already logged in to the LAN data server using the username and password under Windows (IPC$ connection has been established?),
Then I need to use the copy command under DOS to print the plt file on the LAN.

I heard that if you want to print a file on the LAN, you need to map the file path on the LAN to a local virtual drive letter, and then use copy mapped drive letter: prn to print...

I followed this, but there was a problem when mapping:
I used net use z: \\server\data to map the drive letter.

But every time it shows
A system error 1219 occurred.

The provided credentials conflict with the existing credential set.

How should the DOS command be written? How to solve my problem. (It seems that net use needs to establish a connection, and I have already established a connection when logging in to the LAN data server under Windows. Is this conflicting...?)

However, when I directly use net use z: \\server\data under DOS (without establishing any IPC$ connection), the prompt is as follows: The system has a 1326 error. Login failure: unknown username or wrong password.

This problem has been solved... Sweat: When the path contains spaces, the entire path must be enclosed in "" with "". Since the share name on my server is \\server\print data, the command should be net use z: "\\server\print data"

I also break out in a sweat. After thinking for a long time, I didn't figure out the reason. It turns out to be like this.
