NetUserSetInfo() not working on some computers

What im trying to achieve is to reset the BAD_PW_COUNT variable when a another script attempts to login using the LogonUserA API.
For some reason, compiling this script and running it works fine on my machine(the machine the script was compiled on) but not on other machines(Virtual machines). When running the executable, it either always crashes with a exception code of 0x0005(i assume its related to permissions/access denied) or System Error 87. These errors even persists when the executable is ran through a administrative Command prompt and even through PSEXEC running as SYSTEM.

#include <sddl.h> /* for ConvertSidToStringSid function */
int wmain(int argc, wchar_t * argv)
{
DWORD dwLevel = 0;
NET_API_STATUS nStatus;
if (argc != 3)
{
fwprintf(stderr, L"Usage: %s \\ServerName UserNamen", argv[0]);
exit(1);
}
dwLevel = 2;
USER_INFO_2 ui;
ui.usri2_bad_pw_count = UF_SCRIPT | UF_LOCKOUT;
nStatus = NetUserSetInfo(NULL,
argv[2],
dwLevel,
(LPBYTE)&ui,
NULL);
if (nStatus == NERR_PasswordTooShort)
fwprintf(stderr, L"User account %s has been disabledn", argv[2]);
else
fprintf(stderr, "A system error has occurred: %dn", nStatus);
return 0;
}
Any help or guidance is greatly appreciated!. Im sort of new to C++ and Windows API in general as i usually dont deal with this sort of field.

There's nothing in the code you show that is specific to C++, it could be all plain C. And please don't use multiple language tags, only the one you actually are programming in (which in this case could be eithercorc++). C and C++ are two very different languages really. And please read about how to ask good questions, as well as this question checklist.

Error 5 tells you that the account does not have access to that machine. Like System. Error 87 tells you that the USER_INFO_2 struct is not initialized correctly. Use={}to zero-initialize it and provide required field values, like usri2_priv. The last argument of NetUserSetInfo can tell which field is bad.

Just as a complete aside: the example on the NetUserSetInfo does exactly what you're asking to do. Trying to do this, using aUSER_INFO_2structure requires callingNetUserGetInfofirst, to populate the current values.

0x0005is not an (SEH) exception code. If it crashes, the most common reason is an access violation, with code0xC0000005. Using an uninitialized variable (ui) that contains pointers can certainly cause an access violation.
