Try:
When I thought about it, the problem suddenly occurred, and there was no software installed or virus. It was strange.
If the result found on google based on "ExecutionEngineException" is "no medicine to save", make the "worst plan" and reinstall it !. :)
Zookeeper aspnet_wp.exe (PID: 356) unexpectedly stopped "was checked on google and found that the solution on the internet is nothing more than re-installing IIS, re-installing the system, re-installing the framework or vs.net.
In this case, select the simplest IIS reinstallation and find that the problem persists.
Next, choose to fix and install win2003. After installation, the problem is fixed.
We all know that the patches will disappear after the installed operating system is repaired. I updated all the patches one by one and then ran the updates again.
Cause:
Obviously, the cause of the problem is the patch. Keep trying and locate the Microsoft. NET Framework Version 1.1 Service Pack 1 Security Update Program (KB886903) to delete it and solve the problem. Depressed! It took me a whole day to demand "compensation" from Microsoft ". I checked on the Internet and found that foreigners have encountered the same problem: http://www.mcse.ms/message1412685.html.

I searched for a large amount of information on the Internet. This problem is classic and there are many errors, but there is no perfect solution for domestic and foreign websites and forums. After some exploration and attempts, we finally have a better solution. There are three, as follows:
1. re-open an application pool and specify this pool separately for this directory.
2. access permission settings
3. reinstall iis and then install the framework.
My problem is that the access permission is the second problem. Make the following settings to solve the problem:
Under the virtual directory of the web sites, Set Permissions, which should contain
ASP. NET
IIs_WPG
Internet Guest Account
System
The ASP. NET permission must be set to write & read.
After setting, everything runs normally.

This is the case. My machine is equipped with. NETFramework1.1 and 2.0. First, this error occurs in the 2.0 program I opened. After this error is found, the program I typed 1.1 cannot run. I chose the most traditional method to restart my system. The problem still remains unchanged, so I had to reinstall IIS and configure both the 1.1 and 2.0 frameworks. The result is that the 2.0 program can run, and the 1.1 program is still the error.
There is no way to go online and check if there is any relevant information. I saw this article:
Http://www.cnblogs.com/cowbird/archive/2005/02/16/104546.html
But I think the problem is not like that. I thought about it and thought about viewing application logs: Changing the application pool in the next virtual directory. make ASP. NET1.1 and ASP. the NET2.0 virtual directory uses different application pools.
Solve the problem. All right!
The upstairs is a master, and it is indeed an application pool problem. The new pool problem is solved for the ASP. NET2.0 site.
To create an application pool
1. Click Start, point to program, and click Control Panel ".
2. Double-click "Administrative Tools" and double-click "Internet Information Service (IIS )".
3. Right-click application pool, point to new, and click application pool ".
4. Type AppPool1 in the application pool ID text box.
5. Click OK ".
Allocate applications to the application pool
1. Click Start, point to program, and click Control Panel ".
2. Double-click "Administrative Tools" and double-click "Internet Information Service (IIS )".
3. Double-click "Web site ".
4. Double-click "Default Web site ".
5. Right-click DebugApp1 and click Properties ".
6. In the "main directory" tab, select "AppPool1" in the "application pool" list box, and click "OK ". The most important thing is to set the application pool --> properties --> identifier --> predefine the account as the local system.
