NetShareSetInfo() function gives error ERROR_INVALID_PARAMETER

I am doing like this:

PSHARE_INFO_502 BufPtr;

res = NetShareGetInfo((CComBSTR)strComputer,lpszShare,502,(LPBYTE *) &BufPtr;

get BufPtr successfully with res=0.But when I put the same BufPtr like below code:

res = NetShareSetInfo((CComBSTR)strComputer,lpszShare,502, (LPBYTE)&BufPtr, &parm_err);

It gives error with the value of (parm_err = 501 which is SHARE_FILE_SD_PARMNUM(shi502_security_descriptor).

so please tell me what's wrong with this security descriptor.

There is nothing wrong with the security descriptor. You are calling a function that takes 4 arguments with 5 parameters.

Sorry, but I have no idea what may be happening. You will need to use your debugger to check which values may be incorrect.

during debug the error is related to security descriptor.
parm_err = 501 which is SHARE_FILE_SD_PARMNUM(shi502_security_descriptor).

Sorry, but you have already told us that, and I am afraid that it does not help to diagnose your problem. You need to find out why you are receiving that error message. It is possible that you do not have administrative rights on you system, but that is only a guess.
