Upgrading to Windows 2008 R2

Upgrade our testlab machine from Windows 2008 64bit Ent SP2 to Windows 2008 R2 (RC).

What is running on top of it:
- Hyper-V

How to upgrade? Just put in Windows 2008 R2 RC DVD, click for upgrade. It will show the programs/apps that is not compatible, you will need to uninstall some of the apps (that not supported) to ensure a smooth upgrade.

It will then prompt KB957256. As for today, not be able to find this KB article.

We ignore it (cause in a test lab - you might want to test and test and test in a live environment).

After the upgrade, the installation wizard will transfer your files, settings and programs to the R2 environment.

Within 2 hours, everything is up and running. It is the easiet upgade we ever had.

Good job MSFT.

Disable UAC using registry editor

If you would like to turn on/off User Access Control feature in Windows Server 2008 or Windows Vista, you can go to Control Panel > User Accounts. Beside going to control panel, you can also turn it off/on using registry editor, you can find the UAC key in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

EnableLUA (DWORD)= change the value to 1 (On) or 0 (Off)

By the way, try not to disable UAC feature, as this will reduce the security enhancement to protect your workstation and servers in the future

Complex password in Windows Server 2008

Recently, there is a question about password complexity in Windows 2008 Domain.

Windows 2008 is disabled by default and domain is enabled by default.

Now, the complextiy means:

1) Passwords must contain characters from three of the following four categories:
a. English uppercase characters (A through Z).
b. English lowercase characters (a through z).
c. Base 10 digits (0 through 9).
d. Non-alphabetic characters (for example, !, $, #, %).

It is smart enough to get three out of puzzled me for a while.

Getting error "The location for backup is a critical volume" when perform System State backup

As everyone know NTBackup is already remove from Windows 2008 server, if you want to perform a system state backup on Windows 2008 server, you will need to issue a command:wbadmin start systemstatebackup -backuptarget:Drive_Letter: and provided with backup feature installed on your Windows 2008 server.

If you would like to backup the system state on your local C: drive, you may receive the error "The location for backup is a critical volume" and the system will stop you from backing up your system state. If you have additional hard drive attached to your Windows 2008 server, you can always easily change the backup path to another drive, but how if you only got C:
present in your Windows 2008 Server? This scenario mostly exist in virtualization environment, do we really need to attached another volume for the purpose of backup system state?

It is always recommended that store your backup at different locations and always keep the updated backup sets. But in this scenario, you can tweak your Windows 2008 server registry in order to allow system state backup on your system drive and the steps as below:
  1. Open registry editor, browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wbengine\SystemStateBackup\ (Note: If you cannot find the SystemStateBackup key, you may need to manually create it)
  2. Inside the key, create a DWORD value name AllowSSBToAnyVolume and set the value to 1.
  3. You can now backup system state in system drive.
Always, do not forget to backup your registry before you perform the above action, it may corrupt your system if you misused it. ;)
