Sharepoint之配置向导创建DB失败

最近在重装Sharepoint 2010时，运行配置向导创建DB失败，异常的原因也比较奇怪。具体异常日志如下所示：

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，也就是数据库连接不上，查看db服务器，发现DB已经创建成功了，那么就不是这个问题了。然后怀疑配置的域账号权限不够，查看发现是域管理员，并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。最后通过老外的只字片语得到灵感：在运行配置向导时，虽然输入了域账号进行配置，但是配置时并不是使用所配置的域账号，而是使用的当前登录用户。也就是说，不能使用目标服务器本地管理员登录，而应该使用需要所配置的域账户进行登录服务器，然后运行配置向导。至此，折腾了大半天的问题终于解决。
