Up to now, the programs to restart and shutdown the remote computer are complete.

The next is to setup your computer that the webserver is hosted.

(I) Open C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\CONFIG\machine.config. And find the tag processModel and change userName from MACHINE to SYSTEM.

<processModel enable="true" ...="" userName="SYSTEM" password="AutoGenerate" ...="" maxIoThreads="20"/>

Then save it back and restart the computer.

Thus, if you click the shutdwon button in the ASPX page, the remote computer will be shutdown. If your computer doesn't set a password, you can also click the Restart Windows button to restart the remote computer.

If your computer has the passwrod setting, you have to do the next step to let the remote computer automatically restart without human interaction.

(II) Turn on automatic logon with a password

You can use Registry Editor to add your log on information.

To do this, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
   
   
2. Locate the following registry key:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon
   
3. Using your account name and password, double-click the DefaultUserName entry, type your user name, and then click OK.
   
   
4. Double-click the DefaultPassword entry, type your password under the value data box, and then click OK.
   
   If there is no DefaultPassword value, create the value.
   
   To do this, follow these steps:
   
   
   1. In Registry Editor, click Edit, click New, and then click String Value.
   2. Type DefaultPassword as the value name, and then press ENTER.
   3. Double-click the newly created key, and then type your password in the Value Data box.If no DefaultPassword string is specified, Windows XP automatically changes the value of the AutoAdminLogon registry key from 1 (true) to 0 (false) to turn off the AutoAdminLogon feature.
      
      
5. Double-click the AutoAdminLogon entry, type 1 in the Value Data box, and then click OK.

   If there is no AutoAdminLogon entry, create the entry. To do this, follow these steps:
   
   

   1. In Registry Editor, click Edit, click New, and then click String Value.
   2. Type AutoAdminLogon as the value name, and then press ENTER.
   3. Double-click the newly created key, and then type 1 in the Value Data box.
      
      
6. Quit Registry Editor.
   
   
7. Click Start, click Restart, and then click OK.

After your computer restarts and Windows XP starts, you can log on automatically.

After you set up (II), you can remotely restart and shutdown your computer by the ASP.NET.
