I had trouble in Outlook to plan a Skype for Business call after the March updates. When I tried to send the invintation I got an error message that I should make sure that I’m logged into Skype for Business.

I went through all the updates and found out that: KB3114831 is causing the problem. After uninstalling it, it worked like a charm. Hopefully this is going to help somebody.

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
I tried setting the locales with:
sudo dpkg-reconfigure locales

and on raspberry pi with:
sudo raspi-config

But it still didn’t work. You actually need to change the ssh client settings from the computuer where you are connecting from.

Change in:
etc/ssh/ssh_config

Comment:
#SendEnv LANG LC_*

I had a up to 3 second delay each time I right clicked on the desktop or on a folder and this is actually caused by the context menu of the Intel Graphic Driver.

Deleting the Intel Graphic Driver from the context menu fixed it for me:
HKEY_CLASSES_ROOT\Directory\background\shellex\ContextMenuHandlers\igfxDTCM

.\Administrator

Because English is not my mother tongue and I can’t always follow dialogues in movies, I wished a couple of times that there would be a easy way to add subtitles. You can add subtitles with VLC without extension but then you need to have the file already or you need to search in the internet for it.
Luckily you can extend vlc with a great subtitle plugin which automatically searches the internet and finds a suitable subtitle. This saves you some time and steps.

1. Download the extension: https://github.com/exebetche/vlsub
2. Copy the files into the following directory:
   Windows: C:/Program Files/VideoLAN/VLC/lua/extensions/
   Mac OS X: /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
   Linux: ~/.local/share/vlc/lua/extensions/
3. Restart VLC Player
4. Now you should find a new entry for VLSub under extensions.

DISM /Online /Set-Edition:ServerDatacenter /AcceptEula /ProductKey: *****-*****-*****-*****-*****

You can actually deploy ODBC Settings via GPO very easily.

Computer Configuration > Preferences > Control Panel Settings > Data Sources
or
User Configuration > Preferences > Control Panel Settings > Data Sources

ODBC Example with Windows Authentication
New > Data Source
Action: Replace
Data Source Name: Test
Driver: SQL Server

Attributes:
Database: DBName

TRUSTED_CONNECTION: Yes

After you delete files from vhdx disk I noticed that it doesn’t free up disk space on a dynamic vhdx file.

Make sure the vhdx file is mounted read-only or not at all and run following command to free up disk space:
Optimize-VHD –Path C:\Data\Test.vhdx –Mode Full

Important: I could just run this command from a computer where Hypver-V role was installed.

If you have multiple DNS, DHCP, NPS Servers you can install an IPAM-Server to manage them. It also gives you a good overview and statistics.

Important: The IPAM feature can’t be installed on a DC and the computer needs to be joined to the domain. It should also not be on a DHCP/DNS Server.

Quick step by step guide to install it:
1. Install the IPAM-Feature
You will be asked to choose between an WID DB or an MS SQL Server and to pick a GPO name prefix to provisione the servers with a GPO. I picked the WID DB and as GPO name prefix IPAM.

2. Configure IPAM
Connect to IPAM Server
Provision the IPAM Server
Configure Server Discovery (Pick the Domains)
Start Server Discovery

3. After that you will notice that the servers will be populated but showed as blocked. To manage them install the GPOs on the DCs and add the IPAM Server to the Builtin\Event Log Readers Group.

Run following command to install the GPO’s in the powershell as an administrator:
Invoke-IpamGpoProvisioning -Domain contoso.com -GpoPrefixName IPAM -IpamServerFqdn ipam.contoso.com –DomainController dc1.contoso.com

Now you should see in the Group Policy Manager three new GPOs:
ipam_DC_NPS
ipam_DHCP
ipam_DNS

Make sure that in the Security Filtering all the servers which should be managed are added.
Then run a “gpupdate /force” on all the servers.

Then add the IPAM-Server to the Builtin\Event Log Readers Group

4. Even I did everything above it still didn’t show up as unblocked in the IPAM Server Inventory. The trick was to edit the servers manually and untick and tick again the DNS-Server. After that it worked like a charm;-)

If you run the MMC Console as an Domain Admin and you can’t add the event viewer of an remote machine to the mmc console it is probably because of the firewall settings.

Go to the remote machine and run firewall.cpl:
Allow an app or feature through Windows Firewall->Check Remote Event Log Management.

That’s it. Enjoy;-)
