从 Exchange 2003 迁移到 2010 期间安装邮箱角色时出现问题

Question

我正在将我们的域交换服务器从 Exchange 2003 迁移到 Exchange 2010。我以为我已经为服务器准备好了所有必要的角色、权限和更新，但是当我在新的 2008 R2 机器上安装 Exchange 2010 时出现故障。

以下是我迄今为止的步骤；

1) 安装了 Server 2008 R2 SP1 的全新副本（设置了静态 IP，下载并安装了更新）2) 添加了 ADDS 和 DNS 角色 3) 运行 DCPROMO 并将新的 Exchange 服务器提升为 DC。4) 添加了 Web（IIS）角色和管理工具 5) 下载并安装了 Office 筛选包 2.0

此时我继续并开始安装 Exchange，安装过程一切顺利，直到安装到邮箱角色时，我收到以下错误：

我浏览了错误（我承认，当我开始尝试理解它时，我的眼睛有点交叉。）并且我从中提取的唯一（可能）有用的信息是“权限不足”的通知，但我不确定这与哪些权限有关以及如何正确配置它们。

非常感谢您对这个问题的任何指导！
