最近在重裝Sharepoint 2010時，運行配置向導創建DB失敗，異常的原因也比較奇怪。具體異常日志如下所示：
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

值得注意的是該異常：Exception: System.InvalidOperationException: An error occurred while getting information about the user sharepoint at server xxx.com: Access is denied。
根據日志，第一反應是讀寫數據庫權限不夠，也就是數據庫連接不上，查看db服務器，發現DB已經創建成功了，那么就不是這個問題了。然后懷疑配置的域賬號權限不夠，查看發現是域管理員，並且加入到了本地管理員組，那么就不存在權限不足的問題了。
苦思冥想加問技術群，均沒找到思路，而國內沒有任何關於此異常的帖子。最后通過老外的只字片語得到靈感：在運行配置向導時，雖然輸入了域賬號進行配置，但是配置時並不是使用所配置的域賬號，而是使用的當前登錄用戶。也就是說，不能使用目標服務器本地管理員登錄，而應該使用需要所配置的域賬戶進行登錄服務器，然后運行配置向導。至此，折騰了大半天的問題終於解決。
