PVS Console Running Slow?

This is a very old fix but I keep seeing it when attending customer sites. The symptoms are PVS Console is very sluggish and you sometimes get the error :-

“The snap-in is not responding, end now or cancel to return to the MMC to check the status of the snap-in.”

By hitting Cancel the console loads but its very slow.


To fix it on Pvs 6 you should get this prompt….

Click Disable. However if you didn’t click it or choose something else you wont get prompted again.

The best way to fix this is to create a file called mmc.exe.config with the following contents…

<?xml version=”1.0″ encoding=”utf-8″?>
<generatePublisherEvidence enabled=”false” />


Copy this file to c:\windows\system32 and c:\windows\sysWOW64.


On restarting the console you should see the problem resolved;.

Disable Secure Boot on Windows 2012 R2 to install the Citrix VDA – CTX137731

I recently attempted to install the Citrix VDA on a Windows 2012 R2 RDSH server running on Hyper-V 2012 R2 and received the following error …


“ The Virtual Delivery Agent (VDA) does not support Secure Boot, which is currently enabled. “


So I searched for Article CTX137731 as described but it doesn’t exist.

After some investigation it appears that when using Hyper-V 2012 R2 if you create a VM using a Generation 2 Virtual Machine, Hyper-V enables Secure Boot by default as described here


To disable this feature you need to power down the VM and then use the following PowerShell command on the Hypervisor…


Set-VMFirmware –Vmname <VM_NAME> –EnableSecureBoot Off


Hope this helps someone else.

Virtual ISO Drive HDD

I was at a customer site and I needed to build a ThinPC, so I downloaded the ISO and asked one of the guys if he good burn it so I could start the ThinPC image  build process. Then he replied with “We don’t burn ISO’s anymore that’s so 1990’s”. I thought well sure if your using virtualised machines but for physical hardware ??*?

He then showed me his ZALMAN! now calm down that’s not a euphemism, it’s a drive enclosure with a LCD screen. The beauty of this drive enclosure is that there’s some on board intelligence that allows you to present a stored ISO as an external CD/DVD drive.  Brilliant idea, all you do is select the ISO file that’s on the drive and it turns into an external drive with that disk mounted. Great for building servers, workstations or anything that requires a bootable CD. Server engineers could have all the Hypervisor versions on it and techs could have HirensBootCD and the like. Apparently it can mount VHD’s as well but I’ve not tested that.

Anyway I went and bought one as they were so good and at around £35 it’s a bargain! Please see the link to them below.

How to add a second SSD to your MacBook Pro.

I recently got a new laptop at work. Its the Laptop of all laptops, a MackBook Pro 15inch.
We went for the top spec model with a 256GB SSD drive and the High Res AntiGlare Screen. Its really sweet kit.

The only problem is that the 256GB SSD isn’t quite enough for my as I have lots of Virtual Machines which require a lot of storage and I had a Crucial 256GB M4 SSD
drive spare from my old laptop.

I since discovered that you can add a second drive to the Macbook by removing the optical drive which allows space for a second disk. All you need is to purchase a Caddy which I got from Amazon for £25 or there is a one which comes with an external caddy for your optical drive which is around £55. Both of these drives are available here Drive Bay and Drive Bay with External Caddy.

Once delivered I had to get hold of a couple of small screwdrivers luckily a colleague had brought these in for me. (can’t remember the sizes but they are very small. One needs to be a torx)

Heres how to fit the kit…

The Kit

The New Drive bay and my old drive.

Remove the Base

First remove the 10 screws from the bottom plate. Careful not to round the heads. Once removed the metal base will pull off. This did require slight force as there are a couple of retaining grips that hold it to.

Base Removed

Base removed.

Locate the ribbon cable that crosses the drive and remove it from the board.

IMG 4088

Remove the drive connector from the side of the superdrive.

IMG 4090

Now remove the torn screws holding the drive in place.

Lift the cable out of the way

And remove the drive

The SATA interface in the drive bay does not perform as well as the HDD one so I recommend that you remove your existing Apple SSD and put that in your caddy and place your new SSD in the HDD bay.

Remove the existing drive.

Place the drive in the caddy

Put it all back together and Boot up your OS!

Disable Internet Explorer Enhanced Security Configuration (IE ESC)

When building thin client platforms I often have to disable Internet Explorer Enhanced Security Configuration (IE ESC) to get things done. Damn its so annoying!

Using Server 2003 this was quite straight forward, it was as simple as removing the component from the ‘Add and Remove Programs’ Dialog and bobs your uncle.

However things are slightly different in Windows Server 2008 r2, The option is hidden away in Server Management  under the Security Information heading. As shown in the diagram below.

I know I’ll probably get a barrage of reasons why I shouldn’t disable this but Frankly its more a hindrance than it is a benefit.


Track your Iphones GPS location.

Did you know that your iPhone has secretly been logging your GPS location at regular intervals. It has then been storing that information and syncing it with your computer!

This has recently been discovered by two security researchers who have created a Mac application which will show you all your movements of the life of your iPhone.


The data is fairly easy to retrieve using the code on their GIThub site….



Microsoft IT Environment Health Scanner

Stumbled across a new tool from Microsoft which allows you to conduct a health check of your windows Domain configuration. Its mainly for Small to Medium sized networks (recommended 20 servers or less and up to 500 clients) but it will access the overall health of your network.

It highlights problems with the windows network environment. Such as Replication issues, DNS issues and DC health.

Anyway give it a try.

It can be obtained from Microsoft Here.
