  • Blog Post: PKI and Certificate Management Information in Windows Server 2003

    While on the subject of Certificates/Encryption/IPSec/PKI in general yesterday, I was looking around for some good information on how PKI works to post up. One white paper which stuck-out from the pile was published in December last year (so it's reasonably up to date) by David B. Cross and Avi Ben-Menahem...
  • Blog Post: Forms Based Authentication and RPC/HTTP over single IP using ISA 2004

    You would think that this would be something fairly simple to do.... Well, think again, unless you know. In the scenario I was trying to get working, there are essentially three servers involved - a domain controller running Windows Server 2003, a single Exchange 2003 Server and an ISA 2004 Server. ...
  • Blog Post: IIS 7.0 - a first look

    I saw several demonstrations of an early cut of IIS 7 when I was over in Redmond a couple of weeks ago. Again it's Longhorn timeframe material, so much can change and there's little concrete information publicly available. Remember we're way before pre-beta product. One particular demonstration though...
  • Blog Post: Hows Windows stores passwords and how passwords can be attacked

    I was forwarded this by a colleague last week and found it interesting reading. It's a short article written by Jesper Johannson and published last month up on TechNet. It raises many good questions, many of which arise on a frequent basis, but after IT Forum last week, I can kind of now understand why...
  • Blog Post: Deploying Windows Server 2008 with "slipstreamed" Hyper-V RTM. Part 1.

    This article walks through updating an WDS infrastructure such that Hyper-V RTM bits are “slipstreamed” into the operating system installation. Given that Hyper-V has reached RTM (release to manufacturing), it was time to refresh my test deployment environment in my office anyway. I have an entirely...
  • Blog Post: Deploying Windows Server 2008 with "slipstreamed" Hyper-V RTM. Part 2.

    This continues on from last week's post to show the changes needed to enable the "slipstreamed" Hyper-V RTM role at the time of operating system deployment. To start with, follow the steps from part 1 to add KB950050 to each of the images in the WIM file for Windows Server 2008. Then create an unattended...
  • Blog Post: 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...
  • Blog Post: 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...
  • Blog Post: Deploying Windows Vista SP1 with "slipstreamed" Hyper-V RTM. Part 3.

    The first two parts of this mini-series dealt with deploying Windows Server 2008 – either as the root partition with the RTM Hyper-V role enabled, or as a child partition (virtual machine) with the Hyper-V RTM Integration Services installed. This third part covers an additional step for using the same...
