Sharepoint之配置向导建立DB失败

最近在重装Sharepoint 2010时，运行配置向导建立DB失败，异常的缘由也比较奇怪。具体异常日志以下所示：

   1: 9/16/2012 10:49:06  9  INF                    Creating a new farm with config db SharePoint_Config content db SharePoint_AdminContent_b2d2eaa3-a3cf-4420-a100-33926db462c4 server 10.10.10.111 for farm mode

值得注意的是该异常：Exception: System.InvalidOperationException: An error occurred while getting information about the user sharepoint at server xxx.com: Access is denied。

根据日志，第一反应是读写数据库权限不够，也就是数据库链接不上，查看db服务器，发现DB已经建立成功了，那么就不是这个问题了。而后怀疑配置的域帐号权限不够，查看发现是域管理员，而且加入到了本地管理员组，那么就不存在权限不足的问题了。

苦思冥想加问技术群，均没找到思路，而国内没有任何关于此异常的帖子。最后经过老外的只字片语获得灵感：在运行配置向导时，虽然输入了域帐号进行配置，可是配置时并非使用所配置的域帐号，而是使用的当前登陆用户。也就是说，不能使用目标服务器本地管理员登陆，而应该使用须要所配置的域帐户进行登陆服务器，而后运行配置向导。至此，折腾了大半天的问题终于解决。
