Connection Manager Administration Kit for Vista

Curiosity got the better of me. When I was analyzing why Hyper-V Remote Management didn’t always work over a VPN connection due to DNS the other day, I mentioned that I wasn’t familiar with the replacement technology for CMAK in Windows Server 2003. Well, I found it (but it was surprisingly well hidden) – the…


Hyper-V: Why does Hyper-V Manager not always work over VPN connection? Access Denied or RPC server unavailable errors.

This post examines a problem several people have reported when running Hyper-V Remote Management tools over a VPN connection  – specifically hitting an error “Access denied. Unable to establish communication between ‘SERVER’ and ‘CLIENT’”. In some variations, I’ve seen RPC errors such as “RPC server unavailable. Unable to establish communication between ‘SERVER’ and ‘CLIENT’.”  …


Hyper-V: Why is networking reset in my VM when I copy a VHD?

This is a question I’ve seen come up a few times so figured it was time to examine why in a little more detail. In Virtual Server, you were able to copy VHDs and the associated VMC (Virtual Machine Configuration) file from one host to another, add the VMC to the other host and everything…


Hyper-V: MAC Address allocation and apparent network issues MAC collisions can cause

In a physical only world, you don’t usually have to worry about MAC addresses that much as each NIC vendor carves off a MAC address from their ranges which have been allocated to them. However, in a virtual environment, you have to be a little more careful, particularly if you are using dynamic MAC address…


Hyper-V: What are the uses for different types of virtual networks?

If you followed yesterdays post explaining the basics of networking in Hyper-V, you may be wondering what the different types of virtual networks are, when you should use them, and how they look in terms of traffic flow. When you open Virtual Network Manager from Hyper-V Manager, there are three types of virtual network which…


How to remove a failed server from DFS in Windows Server 2003 R2

This week has been a little strained, hence quiet on the blogging front. Apart from a hectic week at work (more to follow on that shortly), the reason was a “disaster” which happened late last Sunday evening – everything was working at home one moment, and dead the next. Since the move over from the…


Enable Remote Desktop Connection through Windows Firewall Remotely

Yesterday evening, I was at home and attempting to remotely connect to my XP desktop machine in the office to access an application which was installed there, but not installed on my laptop. This was over VPN. Now I’ve only had both machines for a few weeks since moving over here and was positive that…


DHCP Client service required for Dynamic DNS Registration

One of those oddities I discovered a couple of days ago after trying to tune down my IIS box which is configured with a static IP address. I stopped the DHCP Client service as I figured (incorrectly) that it wouldn’t be needed due to not using DHCP for that server. I didn’t notice a problem…


Backing up Windows Sharepoint Services

Although I have a fair few ideas as to mini-projects to complete over the Christmas & New Year holiday, it will probably come as no surprise to many of you that there is always the possibility that family will get in the way 😉 On the assumption that I can find enough excuses, one thing…


Part 25: Infrastructure essentials Blogcast – RPC/HTTP for Outlook & Exchange – Integrated Auth

Continuing the blogcast series on infrastructure essentials. The final part to the RPC/HTTPS series shows you how to alter the configuration we have such that Outlook 2003 can move seamlessly between external and internal connectivity through the use of integrated authentication. To do this, we need to change both the ISA server and the Exchange server….
