First of all in order to manage the Windows Server 2008 or Windows Server 2008 R2 based server from Windows 7 RTM, you need to download and install Remote Server Administration Tools for Windows 7.
You can get it from my previous blog post http://blogs.technet.com/aviraj/archive/2009/08/16/remote-server-administration-tools-for-windows-7.aspx or Click Here
Assuming that you have download either x86 or x64 version of the RSAT Tools for Windows 7, we will move further. By default when you install the tools, they are not yet available in Administrative Tools. You have to manually enable what are the administrative tools you require.
Step 1: Download and install the appropriate version of the RSAT Tools. Click Start, click Control Panel, and then click Programs.
Step 2: In the Programs and Features area, click Turn Windows features on or off
Step 3: If you are prompted by User Account Control to enable the Windows Features dialog box to open, click Continue
Step 4: In the Windows Features dialog box, expand Remote Server Administration Tools. Select the remote management tools that you want to install. In this case click on Hyper-V Tools and click on OK.
Step 5: This will install the Hyper-V Manager for Windows 7
Step 6: After the installation click on Restart Now or you can click Restart Later.
Step 7: After the reboot click on Start, Administrative Tools. Click on Hyper-V Manager.
Step 8: This will launch Hyper-V Manager MMC.
Step 9: In the right hand side Actions pane, click on Connect to Server… In the Select Computer windows click on Another computer.
Type the Server you want to manage. In this case it is DEMOSERVER03, click on OK.
