Over the past year or so I’ve come to realise that although my Surface Pro 3 (i5/4GB/128GB) is an awesome machine I just don’t take it out of the house as much as I should be for fear of breaking it. On that note I’ve decided to sell it and in turn replace it with a true beast of the computing world – a Panasonic Toughpad FZ-G1 (link to Panasonic product page).
The astute of you will probably realise that bought new that is a very expensive bit of kit and such I’ve opted for (what I believe to be) a refurbished 1st generation model from Fully Rugged.
- Intel i5-3437U Dual Core @ 1.9ghz (details on the Intel website)
- 4GB RAM DDR3 RAM @ 1,333mhz
- 128GB SSD
- USB 3.0 Port
- HDMI Port
- Ethernet Port (see the photos below!)
- Front and Rear Cameras
- N class WiFi
- Active Digitiser Pen and Capacitive Touch Screen
- LTE Mobile Data Connectivity (WWAN)
- 1.8m drop safe (please don’t test this!)
- IP65 compliant (see link for more details on what this means)
- 1.1kg in weight (yep that’s heavy compared to your iPad Air Gen 88 and no I don’t care! :))
Thus far I am very impressed; the build quality is excellent, I may not feel tempted to drop it from 1.8m to test the specification however I’ve been out in the rain with the tablet and are it didn’t show any issues at all. Having access to a WWAN connection against using the mobile hotspot on my phone is very liberating and Windows 10 will manage connecting to the mobile network for you whenever you are away from WiFi. I haven’t done any real work on battery life as yet however I’ve used it on and off over the course of an 8 hour day and battery life didn’t drop into my head once as something to be concerned by. Resume from standby is as fast as my Surface ever was and performance running web browsing/document editing/playing UWP games is top notch (don’t expect to be gaming on it though).
Over all I am very impressed!
One of my favourite features of PowerShell is the Invoke-RestMethod cmdlet which (among a great many other things) can download the data from an RSS feed. One application I’ve found for this is to stay on top of security bulletins from organisations like Adobe and Drupal.
However just downloading the data from the feed and kicking it out in an email isn’t quite good enough for my needs thus the script below gets data from a CSV which contains the URL to the feed as well as some extra details to inject into any email notification (e.g. a link to the guide on how to deploy Adobe Updates).
In my production environment this script creates tickets on a FreskDesk helpdesk to log and manage any new update notifications. In the attached example below the script just fires off email notifications.
Have a look at the screenshot sequence below for more info!

For the past few months I’ve been using an in house script to manage the rebooting of Virtual Machines on Hyper-V hosts following Windows Updates. These Virtual Machines also take part in Hyper-V Replica Replication to a DR host. On occasion I’ve spotted that when shutting down (as part of the reboot sequence) the Hyper-V Replica state will go into a Error ‘Critical’ state.
As it transpires this happens when the machine is shutting down and Hyper-V replica is attempting to create a reference point to send replica data over to the DR host.
The best fix I have at the moment for this issue is to suspend replication (you can use the Suspend-VMReplication PowerShell Cmdlet as documented here – https://technet.microsoft.com/en-us/itpro/powershell/windows/hyper-v/suspend-vmreplication to accomplish this) before shutting down the machine and then resuming replication (Resume-VMReplication and https://technet.microsoft.com/en-us/itpro/powershell/windows/hyper-v/resume-vmreplication) once shutdown is complete.
You will also note this issue noted under Hyper-V-VMMS in Event Viewer with Event IDs along the lines of 19060, 33680, 32546 and 32026.
While carrying out the steps to move our network devices from a flat network to one with purposeful VLANs I had changed the IP address of one of our HP CP3505 printers (using the web based management console) to discover that with the new IP I could not print to the printer over the network.
Oddly enough the web based management console was still accessible, the printer replied to PINGs and SNMP requests but would not print (that includes from Mac and PC!).
With no error messages other than ‘Error – Printing’ on the server, and nothing in the logs of the printer it seemed like this issue would not have a simple solution.
In trying to troubleshoot the issue I tried…
- Changing the printers IP address to other options (indeed changing the IP back to its original one sorted the problem but was not what I wanted)
- Firmware updating the printer
- Pressing all of the ‘reset’ and ‘clear settings’ buttons I could find on the printer through the WBMC and front panel
- Attaching a network cable between a laptop and the printer direct (no server or switches)
- Removing the jet direct card and leaving it for 30 minutes while the printer was unplugged (oddly enough the jet direct card has a button battery which cannot be removed on it)
All to no success!
In the end and on a complete whim I changed the network settings of the printer to use DHCP instead of Manual IP, reset the printer and then set it back to Manual IP. It was evident that the IP address I had set previously had been forgotten and I set upon the task of configuring the IP address through the front panel. Long behold this worked and the printer is now happyily printing under its new IP address.
As some readers may know I currently work in Higher Education and while all of the business data is trivial to backup providing any level of backup service to students and academics is significantly harder. The challenges faced include the myriad of Operating Systems in use (Windows/OSX/Linux), the fact that the devices being backed up are inherently ‘untrusted’ (i.e. owned by the individual) and that they are often on networks (be it eduroam/public/home) that have no direct connectivity back to the internal trusted network.
Most enterprise class backup systems just aren’t suited to this kind of environment in that they cannot be securely published through a firewall or have exorbitant licencing costs for the number of devices to be protected (a few file servers vs 500+ student owned laptops).
One solution to this issue cropped up at a recent trade show where Synology were demonstrating their Synology DiskStation Manager NAS software which set itself apart from the traditional enterprise backup solutions with…
- Support up to 16,000 users on high end models (and 2048 on the kind of model that we would consider using) with no extra licencing costs, users can have storage quotas set either by group or per user
- Secure remote access (simply publish a single port which can be protected by HTTPS for encryption in transit)
- Home grown backup clients for modern versions of Windows, OSX/macOS and Linux
- On the point of OSX/macOS the backup client for Synology does not rely on Time Machine and so overcomes the issues associated with having to be on the same network as your backup device
- Home grown Btrfs file system which auto detects (and fixes) corrupted files through metadata along with extensive snapshot support
- Up to 32 recovery points and real-time file protection (when connected to the DiskStation)
So time for some screenshots! Below we have the initial setup of the Disk Station Manager and the installation of the client on a Windows PC.
- A business needs to provide backup to remote workers
- Those remote workers do not connect to the trusted network often
- Perhaps they don’t like VPNs/DirectAccess (and so rules out using Offline Files)
- and those remote workers do not use a commercial ‘cloud’ service to protect their data with
- Perhaps trusting a 3rd party to host the data is not an option
- The remote workers use OSX/macOS
- Those remote workers do not connect to the trusted network often
…then using a Synology DiskStation should be a serious consideration for that business.
It’s that magical time of the year where…new network switches arrive! Given that the new Aruba branding has taken full control of what was ProCurve I thought I should post some photos of the new paintwork. Happy to say the colour black isn’t half bad!

So this post is a more a reminder to me than anything else but…having recently come across the Microsoft TechNet article ‘Keyboard Shortcuts for the Windows PowerShell ISE’ (https://msdn.microsoft.com/powershell/scripting/core-powershell/ise/keyboard-shortcuts-for-the-windows-powershell-ise) I thought it necessary to highlight the two keyboard shortcuts….
Ctrl + J – brings up a list of code snippet templates (e.g. try-catch-finally and do-until)
Ctrl + M – expand or collapse braces
See the screenshots below for a demo and do make sure you try them yourself!
After recently deploying a Windows Server 2012 R2 WSUS server (afraid we couldn’t wait much longer for 2016 (which is now out by the way!)) we started seeing Error 8024400E on our clients and servers (from 2008R2/Windows 7 to Server 2012 R2/Windows 10).
As it transpires Microsoft published KB3159706 for the WSUS server which adds some new features to be able to manage Windows 10 updates and thus requires some manual post installation steps which can be found at this link here – https://support.microsoft.com/en-gb/kb/3159706.
The steps only took a few minutes to go through so it was a pretty easy fix in the end.
In this guide I’ll show a ‘working’ method to upgrade from MySQL Server 5.1 to 5.5 on a Windows Server 2008 R2 machine. In this case MySQL Server 5.1 was installed by the Microsoft Web Platform Installer some time ago, however this version doesn’t deliver very good performance (and its horribly outdated!) so it was time to get it replaced.
The good chaps at MySQL do offer a guide on how to do this on their website – https://dev.mysql.com/doc/refman/5.5/en/windows-upgrading.html however I hope you will find this one will serve you better.
A few points to note before we continue….
- This guide assumes you are using a default install of MySQL Server 5.1 (as delivered by the Microsoft Web Platform Installer)
- This guide only looks at a ‘simple’ server deployment i.e. no clustering or other funky features are in use
- It is recommended to jump only one version at a time when going from MySQL version to version e.g. 5.1 to 5.5 (there were no 5.2, 5.3 or 5.4 versions) and then 5.5 to 5.6 and 5.6 to 5.7…
- You can download previous versions of MySQL Server from this link – http://dev.mysql.com/downloads/mysql/ just click on the ‘Looking for previous GA versions?’ link
- Be sure to take a backup of your databases before you attempt this guide on a production machine (see https://dev.mysql.com/doc/refman/5.5/en/backup-methods.html for some ideas on how to do this)
- If possible run through the upgrade process a few times on a testing machine (one that you can break and no one will notice) first
So on with the guide!
Final point to note….this guide only works with migrations to 5.5 from 5.1, if going to further versions you will be missing some tables which will in turn generate error messages during the upgrade process.
