For some time now, IT professionals have been modifying DCOM activation rights in order to keep their System event logs clean. In SharePoint 2010, that fix became slightly trickier, as permissions to modify the DCOM permissions had to be granted through the registry for the IIS WAM REG admin service and oSearch14 DCOM applications. Having made these fixes, I’ve noticed a new breed of DCOM 10016 error.
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{000C101C-0000-0000-C000-000000000046}
and APPID
{000C101C-0000-0000-C000-000000000046}
to the user <FARM ACCOUNT> SID (S-1-5-21-xxxxxxx….) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
The CLSID for this COM Server Application is MSIServer, used to activate the Windows Installer Service. You can find this by navigating to HKCR\AppId and examining the details there:

Recently we’ve been considering a hardware refresh for our developer/consultant/architect laptop build (on Windows Server 2008 R2 Standard with Hyper-V). After a fair amount of deliberation we decided to pilot a new model but stumbled massively at the first hurdle: when we enabled the Hyper-V role on a new Dell Latitude E6410 we got a blue screen. Further testing revealed that the graphics driver was at fault and the SVGA driver worked fine. However, the SVGA driver only has single monitor support. Back to the drawing board.

I’ve just finished watching Virtual PC Guy’s TechEd video on the forthcoming Dynamic Memory update for Hyper-V in Windows Server 2008 R2 SP1. The beta release of the service pack is due in July. The video is fairly lengthy, at around 80 minutes, but is well worth a watch if you’re interested and find the time. If not, here’s a round-up: read more »

With SharePoint 2010 RTM looming, I’ve stumbled across an architectural change that may surprise some people – namely, that SharePoint 2010 no longer supports multiple server farms without a domain infrastructure. In SharePoint 2007 it was possible to create SharePoint farms in a Workgroup, so long as all of the user accounts for the services and application pool identities were named the same and had the same password. You could even manage users with an Active Directory Lightweight Directory Services (AD LDS) or Active Directory Application Mode (ADAM) LDAP directory (albeit with some fairly limiting restrictions). However, it was possible to use these farms for testing or when an Active Directory infrastructure was undesirable (as some people see it in a DMZ). Now, it is still possible to do a Simple installation on a single server without full domain services, but it is no longer supported on multiple servers, and the Simple installation comes with its own planning considerations, to which I’ll return in a bit. First, there’s another wrinkle regarding the single server Complete installation.

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. read more »

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. read more »

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… read more »

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.

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.

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:
