GD & ISAPI don't work

Hi, I've encounter strange problem with GD library. I'm running PHP 4.0.6 on WinNT 4.0 and IIS 4.0. While I use CGI version, each of extensions including php_gd.dll works fine. But when I try change it to ISAPI, it works but without php_gd.dll. All others libraries works fine, but when I add GD lib. IIS will not start with error message: "A system error has occured. System error 1067 has occured. The proces terminated unexpectedly." Do you have any idea how to solve this problem ?
