Reprint: http://blog.csdn.net/ztlyz84/article/details/1906200,http://www.cnblogs.com/luluping/archive/2012/02/07/ 2342068.html,http://hi.baidu.com/278405007/item/95435071cf4a6e10d1dcb344

1. A virtual directory is created

Workaround: Create a new application pool in IIS, then select your virtual directory based on. NET framework2.0, click "Properties"-"Select the application pool you just created in the application pool, and click" OK ".

2. When the new server publishes the Web site, it encounters the following conditions:

Only HTML can be accessed normally, other such as WEBSERVICE,WCF, etc., can not be accessed, display: Server Application unavailable error.

Enter "Event Viewer" stating: No access to system.web.

However, I have set the permissions of the Windows folder to be the same as the permissions of the user who accesses the site.

In addition, the new application pool passed on the Internet is not available.

Finally, my solution is: the properties of the application pool-"identity-" pre-defined account-"to the" local system, the security prompts do not have to ignore him.

3. WORKAROUND: Is the directory permissions problem of IIS, directly to the site directory to give network service users all permissions!
