NetUserChangePassword() Program Example

 

The NetUserChangePassword() function changes a user's password for a specified network server or domain. The following code sample demonstrates how to change a user's password with a call to the NetUserChangePassword() function. All parameters to the function are required.

Create a new empty Win32 console application project. Give the project name and change the project location is needed.

 

 

Then, add the source file and give it a suitable name.

 

Then, add the following source code.

 

#ifndef UNICODE

#define UNICODE

#endif

 

#pragma comment(lib, netapi32.lib)

 

#include <stdio.h>

#include <windows.h>

#include <lm.h>

 

int wmain(int argc, wchar_t *argv[])

{

   DWORD dwError = 0;

   NET_API_STATUS nStatus;

 

   // All parameters are required.

   if (argc != 5)

   {

      fwprintf_s(stderr, LUsage: %s \\\\ServerName UserName OldPassword NewPassword\n, argv[0]);

      wprintf(LExample: %s \\\\MikeServer \Mike Tyson\ 1234 4321\n, argv[0]);

      exit(1);

   }

 

   // Call the NetUserChangePassword() function.

   nStatus = NetUserChangePassword(argv[1], argv[2], argv[3], argv[4]);

 

   // If the call succeeds, inform the user.

   if (nStatus == NERR_Success)

   {

         wprintf(LNetUserChangePassword() is OK!\n);

         fwprintf_s(stderr, LUser password has been changed successfully\n);

   }

   // Otherwise, print the system error.

   else

   {

         wprintf(LNetUserChangePassword() failed!\n);

         fwprintf_s(stderr, LA system error has occurred: %d\n, nStatus);

   }

 

   return 0;

}

 

Build and run the project. The following screenshot is a sample output. Firstly, we set the password to 1234.

 

 

Then we try to change it. Then you may want to log off and re-login using the new password.
