如果你使用ADSI的话
大概应该是这样的
Set obja = GetObject path 
'path 的格式为WINNT://<Domain>/Users/<User>,如果用户在Users下的话
obja.ChangePassword OldPwd,newPwd

如果用ISAPI或者ASP Component
STDMETHODIMP CPwdMgr::ChangePassword(BSTR Domain, BSTR UserName, BSTR OldPwd, BSTR NewPwd, VARIANT_BOOL *RetVal)
{
    HRESULT			hr;
	LPWSTR          wUserName;
    LPWSTR          wComputerName = NULL; // default to local machine
	LPWSTR          wDomain;
    LPWSTR          wOldPassword;
    LPWSTR          wNewPassword;
    USER_INFO_1003  pi1003;
    NET_API_STATUS  nas;
	
	_bstr_t bstrDomain,bstrUser,bstrOldPwd,bstrNewPwd;
	bstrDomain = Domain;
	bstrUser = UserName;
	bstrOldPwd = OldPwd;
	bstrNewPwd = NewPwd;
	
	wDomain = (wchar_t*)bstrDomain;
    wUserName = (wchar_t*)bstrUser;
	wOldPassword = (wchar_t*)bstrOldPwd;
    wNewPassword = (wchar_t*)bstrNewPwd;

	nas = NetGetDCName(
        NULL,
        wDomain,
        (LPBYTE *)&wComputerName
        );

    if(nas != NERR_Success)

    }

    if(wOldPassword == NULL)
	{
        pi1003.usri1003_password = wNewPassword;

        nas = NetUserSetInfo(
