How to convert Physical machine as virtual hard disk
Disk2vhd is a utility that creates VHD (Virtual Hard Disk – Microsoft’s Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that’s online. Disk2vhd uses Windows’ Volume Snapshot capability, introduced in Windows XP, to create consistent point-in-time snapshots of the volumes you want to include in a conversion. You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted).
Disk2vhd includes command-line options that enable you to script the creation of VHDs. Specify the volumes you want included in a snapshot by drive letter (e.g. c:) or use “*” to include all volumes.
Usage: disk2vhd <[drive: [drive:]…]|[*]> <vhdfile>
Example: disk2vhd * c:\vhd\snapshot.vhd

Restoring a Domain Controller Through Reinstallation
Applies To: Windows Server 2008, Windows Server 2008 R2
Restoring a domain controller through reinstallation is the same process as creating a new domain controller. It does not involve restoring from backup. This method relies on Active Directory replication to restore a domain controller to a working state, and it is valid only if another healthy domain controller exists in the same domain. This method is normally used on computers that function only as domain controllers.
Restoring through reinstallation is the only method by which a domain controller that is not part of the backup set can be restored. In addition, you might decide to use this method instead of a nonauthoritative restore because backup media is inaccessible or because this method is more convenient. Restoring a domain controller through reinstallation should not be a substitute for regular backup routines.

Commands and Tools for Managing Windows Server 2008 Server Core
you have a minimal UI that includes a limited desktop environment for local console management of the server. This minimal interface includes:
After you log on to a core-server installation, you have a limited desktop environment with an Administrator command prompt. You can use this command prompt for administration of the server. If you accidentally close the command prompt, you can start a new command prompt by following these steps:
1. Press Ctrl+Shift+Esc to display Task Manager.
2. On the Applications tab, click New Task.
3. In the Create New Task dialog box, type cmd in the Open field and then click OK.
You can start Notepad and Regedit directly from a command prompt by entering notepad.exe orregedit.exe as appropriate. To open Control Panel, type intl.cpl.
Here is an overview of key commands and utilities you’ll use for managing server core installations while logged on locally:

Netsh.exe is a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running. Netsh.exe also provides a scripting feature that allows you to run a group of commands in batch mode against a specified computer. Netsh.exe can also save a configuration script in a text file for archival purposes or to help you configure other servers.
Netsh.exe is available on Windows 2000, Windows XP and Windows Server 2003.
You can use the Netsh.exe tool to perform the following tasks:
With Netsh.exe you can easily view your TCP/IP settings. Type the following command in a Command Prompt window (CMD.EXE):
netsh interface ip show config
With Netsh.exe, you can easily configure your computer’s IP address and other TCP/IP related settings. For example:
The following command configures the interface named Local Area Connection with the static IP address 192.168.0.100, the subnet mask of 255.255.255.0, and a default gateway of 192.168.0.1:
netsh interface ip set address name="Local Area Connection" static 192.168.0.100 255.255.255.0 192.168.0.1 1
(The above line is one long line, copy paste it as one line)
Netsh.exe can be also useful in certain scenarios such as when you have a portable computer that needs to be relocated between 2 or more office locations, while still maintaining a specific and static IP address configuration. With Netsh.exe, you can easily save and restore the appropriate network configuration.
First, connect your portable computer to location #1, and then manually configure the required settings (such as the IP address, Subnet Mask, Default Gateway, DNS and WINS addresses).
Now, you need to export your current IP settings to a text file. Use the following command:
netsh -c interface dump > c:\location1.txt
When you reach location #2, do the same thing, only keep the new settings to a different file:
netsh -c interface dump > c:\location2.txt
You can go on with any other location you may need, but we’ll keep it simple and only use 2 examples.
Now, whenever you need to quickly import your IP settings and change them between location #1 and location #2, just enter the following command in a Command Prompt window (CMD.EXE):
netsh -f c:\location1.txt
or
netsh -f c:\location2.txt
and so on.
You can also use the global EXEC switch instead of -F:
netsh exec c:\location2.txt
Netsh.exe can also be used to configure your NIC to automatically obtain an IP address from a DHCP server:
netsh interface ip set address "Local Area Connection" dhcp
Would you like to configure DNS and WINS addresses from the Command Prompt? You can. See this example for DNS:
netsh interface ip set dns "Local Area Connection" static 192.168.0.200
and this one for WINS:
netsh interface ip set wins "Local Area Connection" static 192.168.0.200
Or, if you want, you can configure your NIC to dynamically obtain it’s DNS settings:
netsh interface ip set dns "Local Area Connection" dhcp
BTW, if you want to set a primary and secondary DNS address, add index=1 and index=2 respectively to the lines of Netsh command.
As you now see, Netsh.exe has many features you might find useful, and that goes beyond saying even without looking into the other valuable options that exist in the command.
