Remote Desktop Connection Manager (RDCMan) manages multiple remote desktop connections. It is useful for managing server labs where you need regular access to each machine such as automated checkin systems and data centers. It is similar to the built-in MMC Remote Desktops snap-in, but more flexible.

Remote Desktop Connection Manager is now available externally on the Microsoft Download Center - get it from http://go.microsoft.com/?LinkID=9733636.

With the release to the public of Exchange 2010 SP1 Beta, it's nice to see the everyone getting their hands dirty with it at long last. Here's a quick post with a few links I've seen and liked over the last few days. As I see more I'll be keeping this list updated. Installing Exchange 2010

Networking in Hyper-V is sort of interesting for those who are used to physical networking or are used to the way networking is implemented in VMware. With Hyper-V, the guest operating systems never have direct access to the hardware, and the Hyper-V management interfaces control the traffic moving through the physical and virtual interfaces.

Hyper-V has a Virtual Network Manager. The Virtual Network Manager is responsible for creating and controlling virtual switches. There is no limit on the number of virtual switches you can create – depending on the type of virtual network you are working with. For example, external virtual networks are basically on physical NICs, so you can only have the number of external networks that is the same as the number of physical NICs.

At some time during the TechEd 2010 conference Microsoft made a significant change in its configuration limits for Hyper-V.

While the previous supported limited for a a single Hyper-V host in a fail-over cluster was of 64 virtual machines, this number has been increased to  384 virtual machines per host.

Ben Armstrong: A while ago I made an open offer to people to contact me if they had experienced issues using Hyper-V backup.  A number of you contacted me with reports of large registry files in the parent partition – that would slow down system boot over time.

Well, after a lot of investigation we have figured out the cause and a hotfix is now available.  You can download it from here:

I recommend that if you are using backup regularly on Hyper-V that you install this hotfix.

Like any other virtualization vendor, of course Microsoft is actively researching to develop more efficient and secure architectures for its hypervisor.

While most of this work remains undisclosed in the Research labs, a few things are being shown in public events.
It’s the case of Bunker-V, the codename for a new architectural approach that Microsoft is evaluating to reduce the Hyper-V trusted computing base (TCB), which today includes the virtual machine monitor (VMM) and the parent partition, equal to over 50 million of lines of code.
