Use System. Management and WMI

Windows Management Instrumentation (Wmi) provides powerful management functions that you can use to manage and monitor Windows-based computers. However, when ASP. NET ApplicationsProgramWhen running with an ASPNET account, this account only has the same default access permissions as the "everyone. These permissions include reading WMI data, writing provider data, and executing methods for the provider on the local computer. For more information about the WMI security mechanism, see the WMI Platform SDK documentation or msdn.
Note:: On Windows 2000 without Service Pack 3 (SP3) or later, or on Windows XP without Service Pack 1 (SP1) or later, ASP.. NET web applications may fail to run, and you may receive an error message "Access Denied (0x80041003)" (Access Denied (0x80041003. This error occurs because the account does not have sufficient permissions to access certain WMI namespaces. To solve this problem, install Windows XP SP1 or later, or install Windows 2000 SP3 or later. To solve this problem, follow these steps:

1.	Open the Computer Management Microsoft Management Console (MMC) Management Unit.
2.	ExpandServices and ApplicationsAnd then selectWMIControl.
3.	Right-clickWMIControlAnd then clickAttribute.
4.	InWMIControl attributesIn the dialog box, clickSecurityTab.
5.	ExpandRoot directory, SelectCimv2And then clickSecurity.
6.	InSecurityIn the dialog box, clickAdvanced.
7.	InAccess control settingsDialog box, clickAdd. SelectLocal Computer Name\ Network ServiceAnd then clickOK.
8.	InPermission ProjectIn the dialog box, make sure thatApplySetThis namespace and sub-namespace.
9.	Ensure selectedAllow 'Enable account'(Allow "enable account") andAllow 'remote enable'(Enable remotely) check box.
10.	ClickOKUntilWMI Control Properties(WMI control properties) dialog box.
11.	Repeat steps 5th to 10th for other WMI namespaces accessed by your application.
12.	Restart IIS. Therefore, run iisreset from the command line.

By default, ASP. NET generates a password with strong confidentiality for the ASPNET account. Therefore, this alternative method is secure as long as the ASPNET account password is not shared between computers or is reset to a non-default value.
