IMHO, one the of the coolest technologies to be released last year was Windows Server 2008 Hyper-V, the virtualisation just rocks, it's fast, solid and reliable. I run Windows Server Core 2008 (ie no GUI) so I manage the Hyper-V Role from Windows Vista Sp1 with Hyper-V Manager, so was a tad disappointed to find the Hyper-V management wouldn't install on Windows 7.
Anyways, fear no more, you can download the updated tools from http://www.microsoft.com/downloads/details.aspx?FamilyID=7d2f6ad7-656b-4313-a005-4e344e43997d&displaylang=en, once installed:-
- Go to Control Panel.
- In the Programs and Features area, click Turn Windows features on or off.
- If you are prompted by User Account Control to enable the Windows Features dialog box to open, click Continue.
- In the Windows Features dialog box, expand Remote Server Administration Tools.
The download link contains more information on setup.
Yes, you still need to enable the firewall and allow anonymous DCOM call backs if you manage a Hyper-V Server that is in it's own workgroup or domain. For more info on this then check out http://blogs.technet.com/jhoward/archive/2008/11/14/configure-hyper-v-remote-management-in-seconds.aspx
