sharepoint：401 unauthorized

轉載http://sharepoint.stackexchange.com/questions/52112/401-unauthorized-when-connecting-from-outside

原文問題如下
I've set up a SharePoint Server 2013 on Virtual Machine. When I am connected to this machine with Remote Desktop and navigate to my SP site with browser, I get to log in without problems. But when I navigate to this site from another computer, after logging in with my username and password, I get 401 UNAUTHORIZED. My site uses Windows Authentication. 
Are there any configuration settings, that I may have missed, that prevent me from accessing this site from outside world?

中文翻譯

我設置了SharePoint Server 2013虛擬機。當我在同網段用遠端桌面連接到本機與可瀏覽到我的SP網站，我可以登錄沒有問題。但是，當我從外部網路另一台電腦瀏覽這個網站，用我的用戶名和密碼登錄後，我得到401 UNAUTHORIZED未授權。我的網站使用Windows身份驗證。

是否有任何配置設置，我可能已經錯過了，這阻止我從外部瀏覽這個網站？

最佳解法

Alternate Access Mappings.

Need to go to Central Admin > Application Management > Alternate Access Mappings > Edit Public URLs and add my full server name to Internet zone.
