SMB Multichannel Constraint FQDN and Hostname

I’ll cover how to make SMB Multichannel actually work in another post, but for now, I’ll just cover the issue. I had configured my SMB networks using the New-SmbMultichannelConstraint Cmdlet to prevent the SMB traffic for my Hyper-V VMs from using my management network and I had assumed that all would work nicely, however when I ran the Get-SmbMultichannelConnection Cmdlet, I noticed that the Client IP and Server IP columns showed the address of my management network adapters and not the SMB adapters when it struck me.

Invalid License Key Error When Performing Windows Edition Upgrade

Last week, I decided to perform the in-place edition upgrade from Windows Server 2012 R2 Essentials to Windows Server 2012 R2 Standard on my home server as part of a multitude of things I’m working on at home right now. Following the TechNet article for the command to run and the impact and implications of doing the edition upgrade at http://technet.microsoft.com/en-us/library/jj247582 I ran the command as instructed in the article but I kept getting a license key error stating that my license key was not valid.

Inaccessible Boot Device after Windows Server 2012 R2 KB2919355

After installing Windows Server 2012 R2, the machine starts to boot and at the point where I would expect to see a message along the lines of Configuring Devices, the machine hits a Blue Screen of Death with the message Stop 0x7B INACCESSIBLE_BOOT_DEVICE and restarts. This happens a few times before it hangs on a black screen warning that the computer has failed to start after multiple attempts. I assumed it was a BIOS problem so I went hunting in the BIOS in case I had enabled a setting not supported by my CPU or maybe I’d set the wrong ACHI or IDE mode options but everything looked good. I decided to try the Optimized Defaults and Failsafe Defaults options in the BIOS, both of which required an OS re-install due to the AHCI changes but neither worked.

KB2992611 Winshock Update and the Broken Cipher Suites

Although it was a nice gesture to add some new cipher suites to Windows, there was a knock on effect to installing KB2992611 and adding these new cipher suites as it appears that Google Chrome for one, possibly more browsers depending on the version you have, do not accept these ciphers and the addition would cause browsers to fail to connect to websites and causing TLS sessions to be dropped. There are also other issues although less widely reported about the installation of KB2992611 causing SQL and ODBC based data connections within applications to drop dramatically in performance.

Thoughts on Windows Server 2003 End of Life

A post by me has a just been published over on the Fordway blog at http://www.fordway.com/blog-fordway/windows-server-2003-end-of-life/.

This post was written in parallel to my earlier post reproducing the Microsoft spreadsheet for cataloguing your Windows Server 2003 environment. I talk about some of the areas that we need to focus our attention and other up some food for thought. If you have any questions then please feel free to get in touch either with myself or someone at Fordway who will be happy to help you.

Windows Server 2003 End of Life Plan Spreadsheet

Last week, the folks over at Microsoft published another entry in their blog post series Best Practices for Windows Server 2003 End-of-Support Migration which included a visually appealing spreadsheet template for helping you keep track of and plan your Windows Server 2003 migrations but to my shock, they didn’t provide the actual Excel file for that design.

Explaining NUMA Spanning in Hyper-V

NUMA Spanning or Non-Uniform Memory Address Spanning was a feature introduced into motherboard chipsets by Intel and AMD. Intel implemented it with the feature set Quick Path Interconnect (QPI) in 2007 and AMD implemented it with HyperTransport in 2003. NUMA uses a construct of nodes in it’s architecture. As the name suggests, NUMA refers to system memory (RAM) and how we use memory and more specifically, how we determine which memory in the system to use.
