奇怪的COM互操作异常0x80005000使用系统.目录服务.帐户管理图书馆

System.DirectoryServices.AccountManagement .

我已经获得了一个用户和分组,就像下面的示例代码,这适用于其他操作,比如启用或禁用帐户。

group = System.DirectoryServices.AccountManagement.GroupPrincipal.FindByIdentity(_UserContext, Name);

user = System.DirectoryServices.AccountManagement.UserPrincipal.FindByIdentity(_UserContext, Name);

现在,尝试将用户添加到组中,如:

group.Members.Add(user);

this codeproject sample 也在做同样的事情。

有没有人看到这个错误,或者知道是什么原因造成的?
