Summary: Solutions for server application unavailable

Before solving the problem, you should first view the error log in the Event Viewer: Start-> Run: eventvwr. MSC;

 

Cause 1: Framework1.1 And Framework2.0 Both exist Server application unavailable Error;

Solution: Create an application in IISProgramSelect your. Net framework2.0-based virtual directory, click "properties"-> select the application pool you just created in "application pool", and click "OK ".

Cause 2: permission issues;

Read data from three folders./Write Permission:

1,C: \ inetpub;

2,Folder where the website is located;

3,FrameworkFolder;

Solution:InVirtual directoryUnder, Set permissions, which should include: ASP. NET, IWAM_machinename, local_service, network_service, System

The permission must be set to write & read.

If the server is win2003 + NTFS, you also need to grant the iis_pwg user the permission. Otherwise, an error will occur when you modify the database !!!!

 

Let's take a look at the security permission settings for this directory:

C: \ windows \ Microsoft. NET \ framework \ v2.0.50727

At leastASPnetUsers andIis_wpgGroup permissions, others. I guess these two are important.
