感谢您使用微软产品。
建议你看看 Q158508 COM Security Frequently Asked Questions (Q4)
如果你的意图是想disable 掉 DCOM/COM+提供的security服务, 在msdn中看看 "turn off security"段；你可以找找以前的帖子看看：http://www.csdn.net/expert/topic/273/273819.shtm微软亚洲技术中心 VC技术支持本贴子仅供CSDN的用户作为参考信息使用。其内容不具备任何法律保障。您需要考虑到并承担使用此信息可能带来的风险。具体事项可参见使用条款 (http://www.csdn.net/microsoft/terms.shtm)。

以下是微软各的答案，然而并没有详细说明该如何办，我也试过http://www.csdn.net/expert/topic/273/273819.shtm
但是我不存在域的概念，用了也不对。This mode does not work unless both sides use local accounts, not domain accounts. For example, I could not use my Test\MarkRy account on Machine1 and a Machine2\MarkRy account on the other machine running Windows NT Workstation. In that case, Windows NT Workstation would have to delegate to its domain controllers, which it does not do. It fails any attempts by a different MarkRy that comes from an distrusted domain (or machine running Windows NT Workstation).
This fallback mode is implicit in Windows NT Workstation to Windows NT Workstation interactions but explicit in interactions between Windows NT Workstation and Windows NT Server. In the case where you want to give access to an machine running Windows NT Server from a Windows NT Workstation user, but the Windows NT Workstation machine itself is not part of the same domain (or of a trusted domain), you need to create a special kind of user account called a "local" user. In the User Manager for Domains, open the New User dialog box, and click Account.
This is how Windows NT Server works with an account from a distrusted machine running Windows NT Workstation or Windows NT Server but, again, only by matching the ASCII account name and the password. "Local" accounts have various restrictions. Basically, they are never delegated for security checks, so they cannot be used in trusted domains, for example. Another significant limit is that a "local" Windows NT Server/domain account cannot be used on any of the Windows NT Workstation or non-DC Windows NT Server machines in that domain because that would also require referral (from Windows NT Workstation to Windows NT Domain Controller). 以上结束
你能给出一个例子吗
这个问题我也遇到过，即使在属性里去掉安全检查，生成实例后还是会出现权限不够的错误,
最终还是采取最土的方式：
1.客户端是COM服务器的域成员
2.若客户端与COM服务器无任何关系，只能让他们的Administrator密码相同。
