How to install Visual Studio Code on Linux Mint 18

I have wrote about the installation of PowerShell Core in Linux Mint 18 yesterday. Today, I want to show you, how to install Visual Studio Code on Linux Mint 18. The installation is really easy:

  1. Download the deb package
  2. Install the deb package
  3. Run Visual Studio Code

You can download the latest packages for Windows, Linux (deb and rpm, if you want even a tar ball), and Mac on the Visual Studio Code download page. Download the deb file. To install the package, open a Terminal window and run dpkg .

sudo  might ask you for a password. That’s it! Now you can simply start VS Code.After you have installed your favorite extensions, VS Code is ready to code. read more

How to install PowerShell Core on Linux Mint 18

Beside my Lenovo X250, which is my primary working machine, I’m using a HP ProBook 6450b. This was my primary working machine from 2010 until 2013. With a 128 GB SSD, 8 GB RAM and the Intel i5 M 450 CPU, it is still a pretty usable machine. I used it mainly during projects, when I needed a second laptop (or the PC Express card with the serial port…). It was running Windows 10, until I decided to try Linux MInt. I used Linux as my primary desktop OS more than a decade ago. It was quite productive, but especially with laptops, there were many things that does not worked out of the box. read more

Workaround for broken Windows 10 Start Menus with floating desktops

Last month, I wrote about a very annoying issue, that I discovered during a Windows 10 VDI deployment: Roaming of the AppData\Local folder breaks the Start Menu of Windows 10 Enterprise (Roaming of AppData\Local breaks Windows 10 Start Menu). During research, I stumbled over dozens of threads about this issue.

Today, after hours and hours of testing, troubleshooting and reading, I might have found a solution.

The environment

Currently I don’t know if this is a workaround, a weird hack, or no solution at all. Maybe it was luck that none of my 2074203423 logins at different linked-clones resulted in a broken start menu. The customer is running: read more

Why “Patch Tuesday” is only every four weeks – or never

Today, this tweet caught my attention.

Patch management is currently a hot topic, primarily because of the latest ransomware attacks.

After appearance of WannaCry, one of my older blog posts got unfamiliar attention: WSUS on Windows 2012 (R2) and KB3159706 – WSUS console fails to connect. Why? My guess: Many admins started updating their Windows servers after appearance of WannaCry. Nearly a year after Microsoft has published KB3159706, their WSUS servers ran into this issue. read more

Secure your Azure deployment with Palo Alto VM-Series for Azure

When I talk to customers and colleagues about cloud offerings, most of them are still concerned about the cloud, and especially about the security of public cloud offerings. One of the most mentioned concerns is based on the belief, that each and every cloud-based VM is publicly reachable over the internet. This can be so, but it does not have to. It relies on your design. Maybe that is only a problem in germany. German privacy policies are the reason for the two german Azure datacenters. They are run by Deutsche Telekom, not by Microsoft. read more

Single Sign On (SSO) with RemoteApps on Windows Server 2012 (R2)

A RemoteApp is an application, that is running on a Remote Desktop Session Host (RDSH), and only the display output is sent to the client. Because the application is running on a RDSH, you can easily deliver applications to end users. Another benefit is, that data is not leaving the datacenter. Software and data are kept inside the datacenter. RemoteApps can be used and deployed in various ways:

  • Users can start RemoteApps through the Remote Desktop Web Access
  • Users can start RemoteApps using a special RDP file
  • Users can simply start a link on the desktop or from the start menu (RemoteApps and Desktop connections deployed by an MSI or a GPO)
  • or they can click on a file that is associated with a RemoteApp

Even in times of VDI (LOL…), RemoteApps can be quite handy. You can deploy virtual desktops without any installed applications. Application can then delivered using RemoteAPps. This can be handy, if you migrate from RDSH/ Citrix published desktops to  VMware Horizon View. Or if you are already using RDSH, and you want to try VMware Horizon View. read more

Tiny PowerShell/ Azure project: Deploy-AzureLab.ps1

One of my personal predictions for 2017 is, that Microsoft Azure will gain more market share. Especially here in Germany. Because of this, I have started to refresh my knowledge about Azure. A nice side effect is that I can also improve my PowerShell skills.

Currently, the script creates a couple of VMs and resource groups. Nothing more, nothing less. The next features I want to add are:

  • add additional disks to the DCs (for SYSVOL and NTDS)
  • promote both two servers to domain controllers
  • change the DNS settings for the Azure vNetwork
  • deploy a Windows 10 client VM

I created a new repository on GitHub and shared a first v0.1 as public Gist. Please note, that this is REALLY a v0.1. read more

Surprise, surprise: Enable/ disable circular logging without downtime

As part of a troubleshooting process, I had to disable circular logging on a Microsoft Exchange 2013 mailbox database, that was part of a Database Availability Group (DAG).

What is circular logging? Microsoft Exchange uses log files that record all transactions and modifications to a mailbox database. In this case, Exchange works like MS SQL or Oracle. These log files are used, to bring the database back to a consistent state after a crash, or to recover a database to a specific point-in-time. Because everything is written to log files, the number of log files increases over time. Log files are truncated, as soon as a successful full backup of the database is taken. read more

Important foot note: Windows 10 Enterprise LTSB 2016 requires a new KMS host key

Today, I have stumbled upon a fact that is worth being documented.

TL;DR: Use the “Windows Srv 2016 DataCtr/Std KMS” host key (CSVLK), if you want to activate Windows 10 Enterprise LTSB 2016 using KMS. Or use AD-based activation. For more information read the blog post of the Ask the Core Team: Windows Server 2016 Volume Activation Tips.

A customer wants to deploy Windows 10 Enterprise LTSB 2016. A Windows Server 2012 R2 is acting as KMS host, and successfully activates Windows Server 2012 R2 and Microsoft Office 2013 Professional Plus. The “Windows Srv 2012R2 DataCtr/Std KMS for Windows 10” CSVLK was successfully installed. Nevertheless, the “current count” value does not increase. The client logged the event 12288: read more

Get-MailboxDatabase doesn’t show last backup timestamp

Sometimes you have to check when the last backup of an Exchange mailbox database was taken. This is pretty simple, because the timestamps of the last full, incremental and differential backup is stored for each mailbox database. You can check these attributes using the Exchange Control Panel (ECP), or you can use the Get-MailboxDatabase cmdlet.

Backup successful, but no timestamp?

Take a look at this output. As you can see, there’s no timestamp for the last full, incremental and differential backup. But this database was successfully backuped some minutes before.
