Matthew has posted instructions over at his blog on how to enable the HyperV extensions that are in the newer linux kernels (2.6.32 and higher). There are two sets of instructions – one on how to build your own kernel and then there are a few pre-built kernels. Note that if you do this, make sure that you disable your software updating mechanisms from updating your kernel automatically, or you will lose seth and the performance boost.
See here for the articles.
The performance boost was amazing and made it worth it to stop using CentOS/RH-based distros…
I am planning on covering the following topics in postings between now and Christmas:
- Windows Mobile vs Android vs iPhone – I’ve had use of all three in the past six months and want to post my recollections about the pros and cons from each of them. I have a clear preference that may surprise you.
- Experiences of a Navision to Deltek Vision conversion – this has monopolized my work life for the better part of the year. I could go on forever for those of you in IT who either need to migrate from Navision (Microsoft Essentials) or if you are migrating to Deltek Vision in general.
- The new ROBOCOPY tool
- Windows 7 Essential Tools for Network Administrators
In general, expect many more review type articles and a lot of tips and tricks. That’s all for now…
My hard drive recovery has been completed.. I’m sorry for the recent downtime, but a combination of events in both my personal and professional life has caused me to delay fixing this site and my personal blog until now.
Due to some changes in my personal life lately and a soon-to-be dramatic shift in my professional life, I’m hoping to restart posting on a much more frequent basis (kinda like how I did two years ago). The past year and a half has been tough for me in transitioning after undergoing traumatic changes at home.
Enough rambling for now…
Yikes.. I haven’t posted here in over a year. Sorry about that… I’ve been much more active on my personal blog for the past year – http://www.jeffreyrandow.org – but I’m just now bringing myself out of my funk… I have some Windows 7, Windows Server R2, Hyper-V, CentOS, and firewall things to bring up over the next few weeks. This is my last week from hell at the office, so maybe I’ll get some time to post more later this week.
Anywho, I’m sorry for the lack of activity….
The server migration has been (mostly) completed… I’m now running the CentOS x64 webserver in a Hyper-V virtual machine on Windows Server 2008 R2 (i.e., the server side of Windows 7). If you are planning on a Linux install on the R2 version of Hyper-V, I would recommend skipping the RC of the new Linux integration components. I get better performance without them… So I’ll wait until they are properly in the kernel sometime in the December/January timeframe…
I still need to do some Apache optimization that I was sorely lacking before.
I’ve been waiting a bit too long to update here and missed a few things…
First, Joseph Davies (aka “The Cable Guy” on Technet) has released the entire TCP/IP Fundamentals for Microsoft Windows in PDF format.

More to come later today or early tomorrow…
I posted an entry over on my personal blog that has described the turmoil, loss, and grief that I have been going through recently and thought that it would be ideal to post here. The following is an excerpt:
As you may or may not have noticed, all of my old content here has been removed. Just over a month ago, a traumatic event happened in my life – the passing away of my mother due to Chronic Obstructive Pulmonary Disease (COPD). As some of you know, I was her caregiver for the past six years since the first diagnosis of COPD. This has caused many ups-and-downs in my life. This loss has left a gaping hole in by existence – one that I am still in the process of recovering from….
See the full article for more information. Thank you for your understanding, thoughts, and prayers through these difficult times.
After spending the past two months wading through the Vista Networking public newsgroup over at msnews.microsoft.com, I have come up with the following tips that will save the users from many problems:
1. If you are having network access/connectivity issues AND you have a Norton or McAfee network security (not AV, but I won’t go there on that one) product, your issue is more than likely the Norton or McAfee product. I haven’t been answering these questions as I made a conscious decision years ago to never let either of these software manufacturers near any computer system I own/manage. However, there have been countless posts in which Norton/McAfee security products are either blocking communications altogether, or have otherwise made networking the PC’s virtually impossible.
2. Make sure you disable network autotuning to get faster file copying/network access to other workgroup/domain computers.
This is easy, though. Run the following command from a Command Prompt as an administrator:
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=disabled
3. If you can’t enable sharing, make sure that you have identified your network as Private. If it is unidentified or Public, you will not be able to enable sharing (without hacking).
I would hazard to guess that these three issues probably represent about 50% of the issues on an average day.
This is from a mailing list that I am on:
So, without further adieu, we are proud to present you with our “ExtraOutlook” tool that allows you to launch as many Outlook instances as you want. All you have to do is configure the profiles you want, and then type: ExtraOutlook.exe “C:\Program Files\Microsoft Office\Office12\OUTLOOK.EXE” (after you download it, of course).
Attendees of past Microsoft Ninjitsu classes have been using it for some time now (as all attendees get special access to the Hammer of God Member’s Site) and we’ve not heard of any catastrophic failures (you know, like having all mailbox data destroyed without any hope of recovery).
I’ve wanted this for a while now and have bugged it in Office 10 and Office 11. I have both a personal exchange account and a work exchange account and have not liked having both. Thusfar, I have coped by using my smartphone for my personal account (as the office does not provide me with cellphone service) and use Outlook for work email.

I want to post a quick update. As some of you noticed, the site had a bit of downtime late last week. I’m sorry that I was unable to post a notice before hand, but I had to undergo emergency server maintenance and I needed to recreate all of my websites from scratch. In the process, I optimized everything and I hope that the site will run much faster for you.
Besides that, I want to wish all of you a happy new year and may this year shower with good fortune (and no server crashes).
I have been spending the past few weeks playing with Windows Home Server, Hyper-V virtualization, and finalizing my Windows Server 2008 beta testing. I also have deployed a CentOS based Voice-over-IP system, created a website for work, and a whole host of fun and not-so-fun activities. I’ve also resumed being active in the newsgroups, primarily around Vista networking and DFS-Replication.
Whats on tap in the near future? I want to review two Linksys router firmware packages – my new all-time favorite Tomato and a new public access point firmware known as Coova. I’m implementing Tomato at home and have used Coova as our new wireless guest portal at the office. Second, I need to update my pfSense review – actually give a 1 year overview. Finally, I want to discuss some of the issues with Samba and Windows Vista.
Again, I would like to thank you for visiting the site. If you have comments, questions, etc, feel free to contact me via any of the mechanisms listed at the top of the site.
