Hi guys i have a problem (i think little), the CopySID fuction return a good SID structure but in the main function the check give a totaly different textual SID! Why? :/
BOOL GetProcessOwnerSid(DWORD dwProcessId, LPTSTR lpszOwnerSid, PSID ptagOwnerSid) {

	HANDLE hProcess;

	HANDLE hProcessToken;

	DWORD dwTokenInfoLength = 0;

	DWORD dwSidLength;

	LPTSTR lpszOwnerSidHeap;

	PTOKEN_USER ptagTokenUser;

	SID_NAME_USE eSidNameUse;

	if ((lpszOwnerSid) && (ptagOwnerSid)) {

		hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, FALSE, dwProcessId);

		if (!hProcess) {

			return FALSE;

		}

		if (!OpenProcessToken(hProcess, TOKEN_QUERY, &hProcessToken)) {

			return FALSE;

		}

		GetTokenInformation(hProcessToken, TokenUser, ptagTokenUser, 

			                dwTokenInfoLength, &dwTokenInfoLength);

		ptagTokenUser = (PTOKEN_USER)GlobalAlloc(GPTR, dwTokenInfoLength);

		if (!ptagTokenUser) {

			return FALSE;

		}

		if (!GetTokenInformation(hProcessToken, TokenUser, ptagTokenUser, 

			                     dwTokenInfoLength, &dwTokenInfoLength)) {

				return FALSE;

		}

		if (IsValidSid(ptagTokenUser->User.Sid)) {

			if (lpszOwnerSid != NULL) {

				if (!ConvertSidToStringSid(ptagTokenUser->User.Sid, &lpszOwnerSidHeap)) {

					return FALSE;

				}

				lstrcpy(lpszOwnerSid, lpszOwnerSidHeap);

				LocalFree((HLOCAL)lpszOwnerSidHeap);

			}

			if (ptagOwnerSid != NULL) {

				dwSidLength = GetLengthSid(ptagTokenUser->User.Sid);

				ptagOwnerSid = (PSID)HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, dwSidLength);

				if (!ptagOwnerSid) {

					return FALSE;

				}

				if(!CopySid(dwSidLength, ptagOwnerSid, ptagTokenUser->User.Sid)) {

                   return FALSE;

				}

				if (!IsValidSid(ptagOwnerSid)) {

				    return FALSE;

				}

			}

		} else {

			return FALSE;

		}

	}

	GlobalFree((HGLOBAL)ptagTokenUser);

	return TRUE;

}
 

int _tmain(int argc, LPCTSTR *argv[]) {
 

	TCHAR szSidName[256];

	PSID ptagSid;

    
 

    GetProcessOwnerSid(932, szSidName, ptagSid);

    LPTSTR lpszSidName = szSidName;

	ZeroMemory(&szSidName, lstrlen(szSidName));

	ConvertSidToStringSid(ptagSid, &lpszSidName);

	

	HeapFree(GetProcessHeap(), NULL, ptagSid);

	Pause();

	ExitProcess(TRUE);
