MCTS Certifications
Posted by Ken Thompson in I.T. Certification, Journal, Work on September 28, 2010

I’ve completed my 70-649 and 70-680 exams successfully. I scored 983/1000 on my 70-680 (Windows 7, Configuring) and 925/1000 on my 70-649 (Upgrading from Windows Server 2003 MCSE to Windows Server 2008, Technology Specialist).
I’m very happy with the results and I’m already starting my studies to acquire my 70-647 (MCITP : Enterprise Administrator), which I plan to do within 2-3 weeks so that I can start focussing on some alternative certifications, specifically VMware and Cisco.
Windows 2008 R2 Server Core
Posted by Ken Thompson in Brain Busters, I.T. Certification, Journal, Work on September 22, 2010
Having just finished studies for my 70-680 Windows 7 exam, I have begun my studies on upgrading my MCSE 2003 to 2008 (MCTS). I’ve been using Windows 2008 / R2 for a bit over a year now and am very familiar with most of the day to day running of it and a lot of the more in depth features also. But this experience has been restricted to time critical real world scenarios; that is to say that I haven’t had time to explore all potentially beneficial features and that when it came to projects I have general stuck to what I know has worked in the past. One of the features I am now very keen to test out is Server Core installation mode. The bar bones version of Windows 2008, with no GUI (command line interface only), but most essential server roles and features. Next week I plan to install some 2008 R2 VMs at home in Core mode to play around with them a little. Some things that I am keen to explore further are:
- Can you install and run any 3rd party applications on server core; specifically Antivirus
- Can you run a file server with DFS enabled and configured
- Do you get much performance increase over a full blown installation…is it worth it for increase performance, or only increase security?
Two Thousand and Ten Geek Goals
Posted by Ken Thompson in I.T. Certification, Journal, Work on January 1, 2010
Well, 2009 was a great year.in all, it went fast and with it brought a lot of big changes with it. I furthered my specialisation in IT, got a beautiful new niece, ended a 7 year relationship, made a bunch of great new friends, dislocated my shoulders countless times and no longer own any mountain bikes at all! There are some pretty epic changes there, but all for the best and stoked to be where I am in my life at the moment and the opportunities I have as a result.
In 2010 I want to further my industry certifications firstly on some well known more broad scope ones such as CCNA (Cisco Certified Network Associate) and upgrading my MCSE from 2003 to 2008. After that I am going to start specialising myself a bit more. I think one of the most interesting and booming areas of IT at the moment is Virtualisation;. VMware definitely has a large presence, but Microsoft and Citrix are really going to challenge this with their excellent and affordable (at times free!) Hyper Visor platforms. In reality, if you can do one of those brands, you can do them all it’s just like driving a different car; essentially everything works the same. I currently use all the Hyper Visor technologies in one form or another at work and at home, but I’m going to choose to specialise in Microsoft Hyper-V virtualisation. While it doesn’t currently have some of the enterprise features of VMware, it has most of the sought after features and is by far the most cost effective solution for SME’s which is the area I would like to stay in. SAN engineering and management is also something that goes hand in hand with virtualisation and something I will also be pursuing.
So I figure I should write down some 2010 New Years resolutions (geek goals!) down so I have something to work towards:
- Obtain CCNA certification
- Upgrade MCSE 2003 to MCSE 2008
- Obtain MCITP : Enterprise Administrator Certification
Non-Geek Goals for 2010:
- Get surgery on at least 1, preferrably both my shoulders to stop them dislocating
- Do a “photo-a-day” photoblog
- Drink a whole slab of beer by myself on Australia Day
- Plan moving to New York to work in 2011/2012
- Get my car license (P’s), next test is the 12th of Jan
- Get my motorbike license (L’s)
Windows 7 Teething Issues
Posted by Ken Thompson in Brain Busters, Journal, The PCs That Kevin Built, Work on June 21, 2009
Well now I have really jumped in the deep end with Windows 7, I’m starting to run into some stumbling blocks. Nothing major, but some teething issues none-the-less. So far I only have 2 issues that are bothering me enough to remember:
(Something to note it is that I am now using 7137 x64 or x86 on all of the PCs)
- VPN Connections not saving passwords: When I create a VPN connection to dial in to work, it will never remember the user name or password, even when the box is checked to remember it. I just can’t work it out and it is definitely a bug which I have reported with feedback. It’s a bit of a pain in the ass having to put it in every time (randomly generated password), but it’s doable. It remembers all the other settings, including security parameters though, so not all lost.
- Issues accessing domain resources on Windows 2003 Domains: I haven’t looked at this issue too much yet, but now that my work laptop is setup with Windows 7 it is becoming a more prevalent issue. Both at work and home, the domains are setup with roaming profiles and redirected folders (my documents). There seems to be an issue with Windows 7 accessing these resources in a timely manner, there is quite a delay and I am not sure what the issue is, with the Windows XP PCs it works just fine. With my home network, the problem even crashes my server; with lots of traffic from bit torrents etc. I’m suspecting some kind of DNS related problem at the moment, but still investigating.
If anyone has any ideas, I’m all ears!

Growing Pains
Posted by Ken Thompson in Journal, Work on April 26, 2009
We have been having an odd issue on our Citrix servers at work since we upgraded them from Windows Server 2000 to Windows Server 2003 in late February. You can’t open MS Access files by double clicking on them, it just does nothing. All the file associations are correct, as are permissions, it’s just a strange occurrence. It hasn’t been high on the priority list to do as users can still open the files from within MS Access using File > Open and navigating to the file from within Access. To be honest, I had completely forgotten about the issue as we had not put in place our ticketting system until recently; I only got it fully setup and functioning last week.
I fixed them up today, we have about 50-60 of our employees using both of these servers at work so it’s impossible to do serious work on them (involving reboots; or risking it) during business hours. Fortunately I can do the work remotely in the comfort of my own home, all rugged up (it’s getting wintery in Melbourne). So fixing the problem didn’t end up being overly difficult, I did a full uninstall of Microsoft Office on our servers (We have 2 in our Citrix “farm”), rebooted them, re-installed Microsoft Office 2003, applied all the updates and rebooted again. I tested both servers and everything looked to be functioning correctly under several different test and live user logins.
During all of the testing I noticed that the scripts for some users were running of a domain controller at another of our sites…not the 2 domain controllers which are at the same site as the Citrix Servers. It wasn’t a big issue, logins functioned, but were just slower than usual as they would travel on a 2MBPS VPN link to the other site (about 10km away), authorize and pull the scripts back down to the Citrix box when a user logged on. When they should have been using 1 of the 2 DC’s in the same room, connected to the same 1GBPS switch! The problem was that Active Directory Sites and Services was incorrectly setup; the DC at the other site was sitting in the main office’s Site OU, not it’s own. So I moved it over, checked that the correct subnets were assigned to the appropriate sites (which they were) and viola; when logging in to Citrix it would now do it faster and use one of the 2 DC’s in the same server room.
Which leads me to the point of my post; our work has grown (and continues to) very rapidly and our IT infrastructure structure and systems were not designed adequately to cope with this. It’s not that anything there is drastically wrong, we have around 150 users who are all working happily away and the systems are performing well enough. But the systems were never designed for much expansion, they were designed to cater for the problems at the time, quick fixes. As such, we have a lot of ad-hoc solutions to problems that have sprung up along the way. It’s like a kid’s tree house with little odd rooms tacked on all over the place!
But quite frankly, I love it! Of course, everything needs to be fixed, a lot of it completely re-designed and implemented from scratch. But it is a great experience for me starting out in IT, I am learning so much every day and putting in place everything I am learning in my Microsoft Certifications. Obviously the aim is to get everything working as smooth and efficient as possible, but it does make me think that if it was all running as smoothly as I plan to have it, work would be very boring.
Aagh, The Serenity
Posted by Ken Thompson in Brain Busters, Journal, The PCs That Kevin Built, Work on April 11, 2009
Finally some time to relax; the past week has been more than hectic. I got all my new gear last Friday night and thus spent all weekend Iincluding Monday which I had off work) painting the internals of my new case, assembling everything and the majority of the time unsuccessfully truobleshooting the issues that I came across. At the end of the weekend I had 2 non-functioning, yet assembled computers.
I was planning to get some work done on these during the week, but work was insanely busy with a critical issue we had with our primary domain controller. For some reason, when any user attempted to log on it was a lottery whether the domain controller would respond properly and load their profile and security settings over the network. It was functioning to the extent it would accept/deny a user for the correct username and password; but beyond that it was pot luck whether the computer would pull down security / profile settings, scripts etc. You could get it working by restarting the PC / logging on and off, as many times as required to make it work…there seemed to be no logic in the problem or solution what so ever. I ended up sounded exactly like the guys from The IT Crowd, “have you tried turning it off and then on again?”.
Fortunately I resolved the problem via use of dcdiag.exe and also by setting up a secondary domain controller on a virtual machine. I resolved several issues using dcdiag.exe and then troubleshooting individual problems, but a key problem we had was that the schema for our domain was not a 2003 schema, even though we are running a 2003 domain. We upgraded our domain from 2000 to 2003 in mid February, part of which you have to run forest and domain preps to upgrade the schemas from 2000 to 2003 before the upgrade; without this the upgrade installation will not continue. Which puzzles me, as the upgrade needed the upgraded schema before installing…yet this week I find that the schema was not the appropriate version. Anyway, while setting up a VM as a domain controller it would not join itself because the schema was incorrect which was the only way I found out about this. After upgrading the schema as well as fixing a few other errors all my domain login issues dissapeared…which was great, I didn’t have to spend all day restarting and re-logging people in until it magically worked!
Anyway, back to the computers, I am still reinstalling my gamer and server and have a heap of photos etc of the whole process which I will put up later in the weekend as well as a bit of documentation on the process and problems encountered…time for another beer.
Installing XP on a Dell Inspiron 1525
Posted by Ken Thompson in Brain Busters, Work on March 30, 2009

I just got a new work laptop, a Dell Inspiron 1525. Pretty snazzy little unit, with a red cover making it as fast as a Ferrari…well maybe not that fast.
Specs:
- Intel(R) Core(TM) 2 Duo Processor T6400 (2GHz/ 800 FSB/ 2MB Cache)
- 4GB DDR2 SDRAM Memory
- 320GB Hard Drive
- 15.4″ Widescreen WXGA (1280×800) TFT Display
- Intel® Integrated Graphics Media Accelerator X3100 Graphics Card
- 8X DVD Burner
- Dell™ Wireless 1395 802.11g 54Mbps Wireless Mini Card
- AverTV DVB-T Tuner Card
The laptop came with Vista Home Premium 32bit and while I like Vista, I am going to put on XP Pro as this is the OS we utilise at work. So it will be better for any error replication I might need to do and guarantees that everything will be compatible with work systems (as we have some custom made programs / database packages). Not to mention being able to log onto the domain, which Home versions of Windows cannot do.
So after hunting around for a correct version of Windows XP Pro with a valid key it was time to install, but I ran into a hiccup. Windows XP setup could not find any hardware drives. The problem here is that it comes factory defaulted to have AHCI (Advanced Host Controller Interface) enabled. You can rectify this be either slip streaming the SATA drivers for the Dell’s HDD into the installation, or add them during setup with a floppy (which it doesn’t have, and XP doesn’t support adding them from USB). But that’s too much mucking around for my liking and AHCI is going to give me no benefits. So I simply disabled this in the BIOS and set the drive to perform as a normal ATA device. Before you can do this I had to disable “Flash Cache Module”, which basically turns part of your HDD into a “flash disk” so it can be used with Windows Vista’s ReadyDrive to supposedly increase read speeds and reduce battery drain. But because I’m not using Vista this won’t be an issue what so ever.
To begin, click your user name…urghh…what user name?

This made me laugh! While locking some computers down for public access using Windows Steady State, I disabled the admin accounts using steady state before I had enabled the actual user accounts. You can still access the admin accounts by pressing ctrl+alt+del twice, but this is still very amusing!
You Know You've Made It In Life When…
Posted by Ken Thompson in Journal, Work on March 25, 2009

As a coffee drinker, you know when you’ve made it in life when you can walk into your cafe on a busy morning, perch yourself on a stool and start reading the news paper. Despite the usual que of 5-10 people, a quick nod from the barista (Steve – Legend!) when I look up from the paper indicates he’s already onto it. A couple of articles later and Steve calls my name; I slink past the que who are obviously admiring my telepathic connection with Steve and thus why my coffee is ready before theirs when I technically never ordered one. I grab my large cup of heaven and stroll off to work, armed to the teeth in caffeine like a nerd commando off to do battle with the PC hordes…it’s the little things in life!
