MAC duplication issues with captured VMs and WDS

I’ve previously reported problems with MAC duplication on Hyper-V host external network connections on Windows Server 2008 R2, which I’ve never fully resolved, although we have been successfully working around the issue as detailed in the first link above.

A couple of weeks ago I was working simultaneously on my Windows Server 2008 R2 laptop with Hyper-V (the same laptop build that’s been previously mentioned) and a Windows 7 x64 build that I was using for testing, when I noticed severe but intermittent network problems on both machines. After a fair amount of head scratching, I noticed that the two laptops had duplicated MAC addresses. Blatantly that shouldn’t happen, as the whole point of a MAC address is to provide uniqueness. The most perplexing issue was that the addresses conflicted across two different operating systems. However, it happened. Both wired adapters on the two machines had the MAC address 00-21-9B-DC-8E-0B. I uninstalled the wired adapter on the Windows 7 machine and scanned for new hardware. When the device reinstalled the problem went away. Continue reading “MAC duplication issues with captured VMs and WDS”

Building a SharePoint 2007/2010 development environment – Part VI: Issues and Results

In the first five parts of this series I covered the project objectives and the system design, then turned my attention to the Hyper-V host image build, automated deployment and the guest virtual machine build. In this post I review some of the questions and issues we’ve encountered after a few months of working this way and some overall reflections on the approach.

Building a SharePoint 2007/2010 development environment – Part V: Guest Build

In the first four parts of this series I covered the project objectives and the system design, then turned my attention to the Hyper-V host image build and automated deployment. In this post I describe a SharePoint 2007 virtual machine build.

Where’s the SharePoint 2010 build?

In short, we’re working on it. I’ve produced a new SharePoint 2010 beta virtual machine for this environment but we’re not yet ready to publish build guidance. Stay tuned. Additionally… Continue reading “Building a SharePoint 2007/2010 development environment — Part V: Guest Build”

Can a hardened server play a SharePoint 2010 Silverlight Media Web Part?

The answer, obviously enough, is that it can if it has Silverlight installed. Read on if you’re interested in how the web part will behave in its absence.

Building a SharePoint 2007/2010 development environment – Part IV: Automated deployment

In the first three parts of this series I covered the project objectives and the system design, then turned my attention to the Hyper-V host image build. In this section I will look at automating deployment of that host operating system. This is lengthy, but there’s a lot to cover.

NewSID myth implications for SharePoint development

It’s now a week on from Mark Russinovich’s NewSID retirement announcement and I’ve been watching the feedback since. To give a brief overview, it’s long been a tenant of machine cloning processes that a new machine SID should be generated for each clone in order to prevent  conflicts. Mark Russinovich wrote the original NewSID tool for Windows NT and as a Microsoft Technical Fellow today, he supposed that it might not be needed anymore and investigated the implications of retiring it. Obviously, if you haven’t read it yet and you work with machine cloning, you should read the article, but if you haven’t found the time to sift through the 168 comments (and counting), this summary might help clarify things:

DCOM IIS WAMREG error 10016 with SharePoint 2010 on Windows Server 2008 R2

Taking a quick break from the SharePoint development series (I hope to finish part IV tonight), Matt Groves has a fix for a slightly more perturbing version of the DCOM IIS WAMREG 10016 error with SharePoint 2010 on Windows Server 2008 R2. His fix works a treat, but I’d recommend granting rights to the WSS_WPG and WSS_ADMIN_WPG local groups in order to make this a permanent fix.

Building a SharePoint 2007/2010 development environment – Part III: Host image build and performance benchmarks

Having agreed the project objectives and designed the system, I turned my attention to the Hyper-V host image build. This is a high-level build guide with start-up time and baseline memory consumption benchmarks at key milestones. These benchmark figures were taken from the Windows Server 2008 R2 Release Candidate build and are admittedly a bit imprecise. However, they do provide an overall indication of system performance as things were added to and removed from the installation. Although I do not have precise figures on RTM improvements, I spot-checked a few of these benchmarks when I rebuilt the system on RTM. Start-up times improved slightly at each milestone. In fact, the final benchmarks came in at 100MB less idle memory used in the RTM release.

Building a SharePoint 2007/2010 development environment – Part II: Design

In the first part of this series, I introduced the pros and cons of various SharePoint development approaches and the objectives of this system redesign. In this part I will focus on design choices and conclusions, starting with the core technology.

Why we’ve chosen Hyper-V

There are broadly five decisive factors: performance, management features (like snapshots), cost, 64-bit OS support and a full host OS (not just a virtualisation administration console): Continue reading “Building a SharePoint 2007/2010 development environment — Part II: Design”

Building a SharePoint 2007/2010 development environment – Part I: Introduction and Objectives

As I’ve alluded to a few times in this blog, over the last few months I’ve led the consultancy and system design for a SharePoint 2007/2010 development environment built on Hyper-V in Windows Server 2008 R2. This series of six posts will reveal the key decisions and will consolidate recommendations from a broad range of research and guidance. This first post offers a technology-agnostic introduction to the problem, pros and cons of alternative approaches and what we hoped to achieve with the new approach. The design decisions will be covered in more detail in the second post, followed by a deeper look at detailed build guidance.
