Microsoft Belgium At The Speed of Light, Traffic At A Glacial Pace, AD FS 2.0 , Vittorio Bertocci & a Large Chocolate Bunny

Wednesday April 27th 10:45

We’re helping out on the infrastructure side of a claims based authentication project with my team and I had some questions on AD FS 2.0. The two lead developers (U2U Consult’s Kris Vandermotten & Stefan Gevaert ) also had some outstanding questions or rather they needed a echo chamber to discus some design choices.  Now imagine you have TechDays 2011 going on in your country and Vitoria Bertocci (http://blogs.msdn.com/b/vbertocci/, @vibronet ) is over there to present a decent amount of sessions and is available to the attendees for questions.  OK I have two people of my ICT team running around to broaden there horizons but I’m at the office holding the fort. Kris says he saw Vittorio the day before but missed an opportunity to talk to him on Tuesday.  I’m thinking & saying , yeah I should mail him. I really should. Why haven’t I yet?

Wednesday April 27th 14:20

Kris & Stefan suggest to go to Antwerp and meet up with Vittorio. I’m thinking like, good plan but how do we get this set up so fast? Mail? Nah, what if he isn’t able to read it.  We need an other approach. I decide to use two channels. Twitter and telephony. One tweet (with a very fast response from Vittorio) and some phone calls to Microsoft employees I know might be at TechDays 2011. The first two are not there that day but Arlindo Alves (@aralves) is. I get him on the phone very quickly (note that he is extremely busy during an event like TechDays) and ask him if we can set up a meeting with Vittorio. He says he’ll ask and will get back to me. Well it’s 15:00 hours and we have a meeting set up for 10:00 hrs Thursday morning. Wow Smile Now I’m impressed with how fast this went from “let’s try” to reality.

Thursday April 28th 08:00 hours

We’re leaving in Gent to go to TechDays at Metropolis in Antwerp.

Thursday April 28th 10:05 hours

We arrive at Metropolis. Wow again but not in a positive way. I’m not impressed at all at the “speed” we got to Antwerp. I’m not even sure if you can call what I witnessed driving anymore. But hey, there is a reason I love telecommuting, riding my bicycle to work and using the train to commute.

Thursday April 28th 10:10 hours

We start a very interesting and fruitful talk with Vittorio about our project. He’s extremely knowledgeable on the subject, passionate about the technology and he loves to help people understand and use it better. We’re happy with what we learned and the talk ends with us keeping our promise to Arlindo & Vittorio. We brought Belgian chocolates. Now, we didn’t exactly manage to get “pralines”, it was a bit larger (http://twitpic.com/4qglxb). For some reason we think he’ll remember us when we send him a follow up mail.

Lessons learned. If you need to talk to some one at Microsoft don’t be afraid to ask. Also be willing to act fast and to grab an opportunity because people like Arlindo Alves from Microsoft Belgium are very good at making them happen!

New KB Article 2494016 Related to Windows Server 2008 SP1 Hyper-V: Stop error 0x0000007a When Using CVS in Redirected Access

Well not a day after my blog post Extra Info on Clustering & Hyper-V with Dynamic Memory When You Start With Windows Server 2008 R2 SP1on important hotfixes for Hyper-V clustering with Windows Server 2008 R2 SP1 Microsoft releases a new hot fix for issue below. I’ll add it to the post to keep up to date.

Stop error 0x0000007a occurs on a virtual machine that is running on a Windows Server 2008 R2-based failover cluster with a cluster shared volume, and the state of the CSV is switched to redirected access

The KB article with instructions on how to get the hot fix is here: http://support.microsoft.com/kb/2494016/en-us?sd=rss&spid=14134

The scenario is detailed as follows:

Consider the following scenario:

  • You enable the cluster shared volume (CSV) feature on a Windows Server 2008 R2-based failover cluster.
  • You create a virtual machine on the CSV on a cluster node.
  • You start the virtual machine on the cluster node.
  • You move the CSV owner to another cluster node, and you change the state of CSV to redirected access.
  • The connection that is used for redirected access is switched to another connection when one of the following scenarios occurs:
    • The cable for local area network (LAN) is disconnected.
    • The related network adapter is disabled.
    • The connection is switched by using Failover Cluster Manager.

In this scenario, you receive a Stop error message that resembles the following in the virtual machine:

STOP 0x0000007a ( parameter1 , parameter2 , parameter3 , parameter4 )
KERNEL_DATA_INPAGE_ERROR

Note

  • The parameters in this Stop error message vary, depending on the configuration of the computer.
  • Not all "0x0000007a" Stop error messages are caused by this issue.
  • You may also receive other Stop error messages when this issue occurs. For example, you may receive a "0x0000004F" Stop error message.

Extra Info on Clustering & Hyper-V with Dynamic Memory When You Start With Windows Server 2008 R2 SP1:

Here’s a quick “heads up” if your starting to use or thinking about using Windows Server 2008 R2 SP1 for your Hyper-V clusters. The most common issues I’ve seen in the wild are:

  1. https://blog.workinghardinit.work/2011/04/01/kb2230887-hotfix-for-dynamic-memory-with-windows-2008-standard-web-edition-does-not-apply-to-without-hyper-v-editions/ This one is being worked on and the hotfix will be re-released to support the “Without Hyper-V” SKU of Windows Server 2008 SP2.  It’s a simple oversight but one that can be important when your Hyper-V clusters are filled with that SKU.
  2. We also got bitten by this one Déjà vu Bug: The network connection of a running Hyper-V virtual machine may be lost under heavy outgoing network traffic on a computer that is running Windows Server 2008 R2 SP1, but the hotfix was already available luckily.
  3. And than one to head and to read the TechNet forum about Cluster Validation Bug In Windows 2008 R2 SP1 – Disk has a Persistent Reservation on it. They are also working on a fix. I’ve written a blog post on this and I suggest you read it and also take note of the discussion in the TechNet forum.

    UPDATE: The hotfix for issue 3 has become available today, April 26th 2011 as announced on the TechNet forum here:

    A hotfix is now available that addresses the Win2008 R2 service pack 1 issue with Validate on a 3+ node cluster. This is KB 2531907. The KB article and download link will be published shortly, in the mean time you can obtain this hotfix immediately free of charge by calling Microsoft support and referencing KB 2531907.   Update 27/05/2011 Here is the link: http://support.microsoft.com/kb/2531907/en-us?sd=rss&spid=14134

An other one that I haven’t seen in the wild is:

Windows Server 2008 R2 installation may hang if more than 64 logical processors are active. There is is a workaround and a hotfix for this one.

Issue: When you try to install Windows Server 2008 R2 on a computer that has more than 64 logical processors, Windows Setup may stop responding in one of the following operations:

  • Initialization of Windows Setup
  • One of the two restarts that are required to complete Setup

Cause: This issue occurs because of an error in the Network Driver Interface Specification.This issue occurs because of an error in the Network Driver Interface Specification (NDIS) driver.
When a computer has more than 64 logical processors, the NDIS driver does not correctly handle some operations. Therefore, the computer encounters stop responding issues and other system failures.

I don’t have any nodes under my care who have more than 64 logical processors so that’s why I guess Smile But with ever more cores available you it’s bound to happen in the near future.

Update 2: To keep me busy this KB article was released within 24 hours of me posting this blog on a BSOD with CSV and redirected access for witch a hot fix is available

The Dilbert® Life Series: The Carbon Copy, Blind Carbon Copy e-mail Pandemic

Disclaimer: The Dilbert® Life series is a string of post on corporate culture from hell and dysfunctional organizations running wild. This can be quite shocking and sobering. A sense of humor will help when reading this. If you need to live in a sugar coated world were all is well and bliss and think all you do is close to godliness, stop reading right now and forget about the blog entries. It’s going to be dark. Pitch black at times actually, with a twist of humor, if you can laugh at yourself.

Have you ever worked in an office where no one ever takes responsibility and all communication is CC’d and BCC’d to an absurd number of people? There are corporate “cultures” that act very different from our own style. Size often has nothing to do with it. But this habit is just another symptom and indication of blatant management failure.

These are organizations where no one feels like they can make decisions or take actions without involving half of the company in some form of meeting or committee. CYA (Cover Your Ass) in action. One of the symptoms is the fact that just about anyone who has (or thinks they have) some important or urgent information sends all mail with some managers in CC or even BCC. Often the middle management acts the same way and before you know it more CC & BCC recipients are involved making the entire mail flow a mess and proving without any doubt that you’re in kinder garden. Decisions are postponed or never made. No one is going to take responsibility for a decision, that much is for sure. So when a decision is finally made it often by the wrong person, too late and probably not the best one. Basically, you have a management structure where no one knows who’s responsible and is utterly dysfunctional

This is also a symptom of another issue: managers without authority. Yes, they are not very good at their area of expertise; they can’t delegate or organize and lack real people skills. These are often found in middle management where they can be used by the upper level. After all, there needs to be someone between the hammer (management) and the anvil (employees). You see authority does not come from your rank or pay grade. It comes from what you know and can do and the support you get from other well-respected managers or leaders. If you need to CC all your bosses and all bosses of the people you’re emailing, this indicates that you’re a whining kid that can’t hack it. And no, simply not using CC or BCC anymore won’t solve that problem. I thought I’d mention this as they tend to think and act rather simplistic. We have a saying: “You salute the rank, not the man. You respect the man, not the rank.”

Anyway, the mail process is as most people in the mail are not involved, don’t care, don’t need and shouldn’t care, and hopefully don’t want to care. Once it got so out of control I added some more people to the CC list and wrote sarcastically at the top of the mail body that we really should make an effort to senselessly involve as many people as we possibly could. Not very nice, I know. Shouldn’t do that, I know. Some got the message, some didn’t. Another solution is to ignore the mail. Really if so many people, including a bunch of managers above and way above me, are in the CC list I would not have the arrogance to assume I have anything to say in the matter and thus I await their proposals or decisions.

The best employee a manager can have is Vanilla Ice. Really “…If there was a problem yo I’ll solve it …”, that’s what a good manager needs and wants. You see your boss has better things to do than micro-manage the details of your incompetence. You know your end state, so all you need to do is figure out what you need and how you’ll achieve it. Results, that’s what your boss really needs, not details, and moaning about how hard middle management is. I know shit flows down and gripes flow up but try to maintain a balance or you’ll find yourself holding a pink slip or being promoted to where you can do the least damage and annoy the least amount of people. I secretly think some people have that as a cunning plan.

But if you’re stuck with a couple of micro-managers, do not despair. You can work around them unless they surround you. In the latter case, break out and run! They deal with urgent and very pseudo important problems that are actually just details which are benign in nature and are not negatively affected by all that overzealous attention. So the trick is to keep it that way. You have to treat them like mushrooms: keep them in the dark and feed them shit. As long as they don’t know any better and keep getting their “data” fix they are lovable. Whatever you do, don’t give them real information or show them the real problems. Micromanagers really can’t handle them. Ambitious ones that get into the light and get gourmet food can become very dangerous. Both to themselves and the organization. Now you do need them to keep them involved and they need to sign and approve work and proposals. So give them finished work, solutions that are ready to go. Forget about involving them in the details or the decision-making process, they’ll just get lost. And guess what, this is like a good boss should work and act so we have a win-win situation for the entire company!

Now you know how to help prevent that e-mail becomes a burden instead of a useful tool. No CC or BCC unless really needed. Go practice it.
