Windows 2008 Server R2 Auto Login

I am using Windows 2008 Server R2 as my laptop OS, after joining to company domain, the auto login feature was not working any more. Today I found a blog and made my day:

 http://www.expta.com/2008/04/how-to-enable-autologon-for-windows.html

 For reference I copy the commands:
 reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d "1" /f

Run control userpasswords2

To set default Domain name
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultDomainName /t REG_SZ /d %USERDOMAIN% /f

Alternatively using reg file (didn't try):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"AutoAdminLogon"="1"
"DefaultDomainName"="DomainNameGoesHere"
"DefaultUserName"="Administrator"
"DefaultPassword"="AdminPasswordGoesHere"

A craftsman who wishes to do his work well must first sharpen his tools.

There is a mission impossible on Windows 2008 R2 Server: using hibernate function on a Hyper V enabled server, please leave a message if you know how to do it, I worship you as a guru ^_^
