Wait a minute… Virtual Machine isn’t “highly” available though it is on a Clustered Host?

It is possible, albeit an edge case, that you have both clustered (highly available) and non-clustered virtualization farms in your data center.  You’ve got your virtual machine (VM) configurations and hard disks stored on Cluster Shared Volumes (CSV) and your non-clustered VMs stored elsewhere (potentially on SANs but just not CSV’s).  It is recommended for…

VhdTool & “Save your bacon” – Extend base virtual machine while snapshots exist is bad JooJoo

I recently was privy to a situation whereby an individual (this person’s identity is concealed to protect the innocent) realized that a virtual machines dynamically expanding disk simply wasn’t large enough.  This person realized this during some upgrades to key components running on the server and was quickly & swiftly maneuvering around the Hyper-V console…

The Inside & Out of Authentication in IIS – Anonymous, Basic, Integrated, and much, much more!

Several, several years ago I remember having this topic in the IIS Webcast Series and what strikes me from back then is the fact that I recall having a conversation with a currently high-level (think executive) individual.  The conversation was around the fact that he/she didn’t think anyone would attend this Live webcast.  I remember…


Heading to MMS 2010 – One Presentation & lots of customer discussions…

As many of you already know, Microsoft is preparing for next week’s Management Summit 2010 in Las Vegas.  This is a great event, not only for his content but also its incredible knowledge transfer capabilities.  As a team member in the greater Management & Services Division (MSD) at Microsoft I can tell you this is…


SCVMM 2008 R2 & Cluster Shared Volumes (CSV) Migration from one CSV to Another

You often do your job of “planning” for your virtualization farm well in advance of when you can realistically foresee the amount of storage you will need.  If you like me, you often take the amount of known needed space and you triple it – shh, don’t tell management.  This technique works great until you…

Hyper-V Lingering Internal NICs – Unable to Remove

I recently had a Windows Server 2008 R2 server running the Hyper-V role with some Internal NICs created for private “sandboxing” of some VMs.  After adding some additional virtual machines to utilize the Private NICs, I was up and running.  This turned out to be a temporary situation until we put another server into production…


Failover Clustering Validation Wizard Fails when Enterprises uses IPv6 and IPv4

Recently, I had a server that I had to forcibly evict from our Hyper-V Cluster farm due to some downtime for hardware failures.  Instead of having it serve as offline, I simply migrated the clients off before the failure occurred using System Center Virtual Machine Manager R2’s Maintenance mode.  Then I used the Failover Cluster…

Failover Cluster Networks & Local Networks – Phantom Network listed in Failover Cluster Manager

You’ve recently had a request to add a few virtual machines to your Clustered Hyper-V farm and you’ve obliged them and created it using SCVMM’s administrator console.  You’ve created the network as a “Local Only” meaning that the VMs can communicate with each other as well as the Parent partition on the physical host (as…


Failure during Windows Server 2008 System State Backup & System Writer Missing

For some of those new to DPM 2007, you might find yourself in a situation where a Windows Server 2008 (and R2) is failing during backups consistently.  The consistency part is the ironic is that it is always failing and might lead you to review a bit more what is going on.  This problem, as…

Unable to Extend System Volume & DPM Backup Failure: Change the System State backup location

I recently had a couple of servers where they had rather small system partitions, one was Windows 2003 while the other was Windows 2008 RTM and DPM continued to fail with replica is inconsistent errors.  The DPM documentation and event errors were referencing the replica and volume partition size(s) and all checked out with plenty…
