Event – TrueSec Infrastructure Summit 21 of June–summer 2016

Posted by Mikael Nystrom on May 24, 2017

(Note: This event is held in the Swedish Language)

Vi har nu kört Windows Server 2016 och Windows 10 under lång tid och vi har samlat på oss så mycket erfarenhet, en del fantastiska upptäckter, en del mindre lustiga. Vi tror att du vill veta det här, så att du kan undvika “slukhålen” som vi själva har trillat ner i. Det här gäller så klart både på klientsidan där vi trodde att man skulle få helt andra problem än vad man verkligen fick, samma sak på datacenter sidan, det blev inte riktigt som vi trodde. Så vi har samlat ihop gänget som är där ute och jobbar och sliter varje dag och kör en heldag på Rival i Stockholm. Kan du inte komma dit, kan du sitta hemma i soffan och njuta ändå, vi kör ju med LiveStream. Så, ta genvägen till erfarenhet, och häng med oss på Rival, Stockholm!

OSD – Workaround for ADK issue in 1703

Posted by Mikael Nystrom on May 16, 2017

The issue in ADK 1703 is that you cannot mount a WIM file in MDT/ConfigMgr, due to a signing issue with the WIM Mount Driver when running a system with UEFI and Secure Boot.

Workaround:

Michael Niehaus did found a workaround today, and that is to use the existing WIM mount driver that is already in the system.

PowerShell is King – A Data Deduplication script that runs the Optimization,Garbage Collection and Scrubbing in a single sweep, including progress

Posted by Mikael Nystrom on April 28, 2017

I use Windows Server 2016 on all my lab machines, therefore I also use Data Deduplication to save space. But I don’t run it in the background, i run it basically when I need space.

The PowerShell script. (https://github.com/DeploymentBunny/Files/tree/master/Tools/Start-VIADeDupJob)


Function Wait-VIADedupJob
{
while ((Get-DedupJob).count -ne 0 )
{
Get-DedupJob
Start-Sleep -Seconds 30
}
}

foreach($item in Get-DedupVolume){
Wait-VIADedupJob
$item | Start-DedupJob -Type Optimization -Priority High -Memory 80
Wait-VIADedupJob
$item | Start-DedupJob -Type GarbageCollection -Priority High -Memory 80 -Full
Wait-VIADedupJob
$item | Start-DedupJob -Type Scrubbing -Priority High -Memory 80 -Full
Wait-VIADedupJob
}
Get-DedupStatus

Nice to Know – Performance guidelines for Windows Server 2016!

Posted by Mikael Nystrom on April 27, 2017

Yesterday, Microsoft announced the availability of performance guidelines for Windows Server 2016. They are not super advanced but they are perfectly fine. One nice thing is that you can view them offline (you don’t always have access to a fancy Internet connection working in a datacenter. My take on this is that you should browse trough the topics that you work with, take the ideas, convert them into reality and implement them in your deployment process. As they say in an old movie, and I quote:

– I feel the need, the need for more speed…

Nice to Know – IT Pro documentation for Windows 10 is now on Microsoft Docs

Posted by Mikael Nystrom on April 27, 2017

So, Microsoft has “moved” W10 documentation to http://docs.microsoft.com. It does make sense, the “docs” site is better suited for having this information then TechNet/Msdn.

Working in the Datacenter – SCOM 2016:Import management packs install button grayed out

Posted by Mikael Nystrom on April 26, 2017

The Issue:

I was about to import management packs for System Center Virtual Machine Manager 2016, but the install button was grayed out? Ok, so let us do what we always has been doing, remove the already imported MP’s, but then it all gets red and error, hmm

image
Install button is greyed out.

Let us try to remove the already imported MPs…

image
All already imported MP’s have been removed, still not possible to import…

The Solution:

By removing just “Microsoft System Center Visualization Virtual Network Dashboard” it works…

image

Hey, it works…

It seems that this is not only true for this scenario, here is a blogpost that explains the same issue when importing the SQL MP.

Working in the Datacenter – Update all agents after upgrades and rollups

Posted by Mikael Nystrom on April 26, 2017

It is possible to manually upgrade each agent, but that is just wasting time on something really boring, so let us do PowerShell instead

image

#Get the Admin Account
$AdminAccount = Get-SCRunAsAccount -Name ‘SCVMM Admin’

#Update the Agent
foreach($item in (Get-SCVMMManagedComputer)){
    Update-SCVMMManagedComputer -VMMManagedComputer $item -Credential $AdminAccount -RunAsynchronously
}

Nice to Know – Membership in a Local group contains only SID numbers in Windows Server

Posted by Mikael Nystrom on April 26, 2017

Ok, so from time to time this happens, it should not, but it does

Issue:

You open the local Administrator group and all domain user accounts is just SID numbers, (a few could actually be names, but that is not very common). It looks like this:

image

Solution:

I’ll guess there are many ways to fix this, but the Quick and Dirty is to:

– Disjoin the domain (don’t restart)

– Join back

– Restart
