For those that do not wish to use OneDrive and want it removed from the folder tree in Explorer, can do so by a simple registry change:

Open regedit and locate the key: HKEY_CLASSES_ROOT\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}

Change the value of System.IsPinnedToNameSpaceTree to 0

When using 64-bit, repeat the process for the key: HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}

Note that starting from Windows 10 Creator, you can also remove OneDrive by uninstalling it:

  • Right-click OneDrive in the start menu and click "Uninstall"
  • Go to Control Panel → Add/Remove Programs and uninstall it from the list.

As found on Voip-info.org, a list of bandwidth consumption per codec.

It's worth mentioning that the table also indicates the total consumption including IP overhead. When making assumptions about bandwidth requirements, it is useful to take this overhead into account.

G.729 8 Kbps 31.2 Kbps
G.723.1 6.4 Kbps 21.9 Kbps

You can easily verify whether an ADFS implementation is working by using a browser and trying to log on:

https://adfs.yourdomain.com/adfs/ls/IdpInitiatedSignon.aspx

Replace adfs.yourdomain.com accordingly.

Note that in 2016, this no longer works unless you re-enable this feature through Powershell:

Set-AdfsProperties -EnableIdpInitiatedSignonPage $true

To properly shut down the NetApp (through the CLI):

First, close down all I/O to the NetApp by dismounting volumes, turning off servers, etc.

Log in on the NetApp through the CLI, using either a console cable or via SSH. Note that if you use SSH, you will not be able to see the complete shutdown sequence.

On the first controller, turn off cluster failover: cf disable



Shut down the controller: halt



Log on to the other controller (using SSH or swap the console cable), then shut down that controller too: halt



Wait until the shutdown sequence has completed before removing power from the controller chassis, then turn off the enclosures. You can use a console cable to verify whether th  ...

To create an UEFI-bootable USB installer for ESXi 6.5 (or newer) on a Mac, follow the steps below.

First, you'll need an USB flash drive. Any recent drive will be large enough (you'll need at least 512MB). Also, download the latest ESXi installer ISO from My VMWare. You probably need a My VMWare account.

With the prereqs in place:

Insert the USB flash drive in the Mac and start up Disk Utility.

Erase the USB flash drive and choose to format it:Partition map = MBR

Filesystem = FAT32

Give it a descriptive name of your choosing.

After erasing the drive, we still have to mark the one partition on it as "active". Disk Utility does not support this and needs to be done using Termi  ...

The RLM module may become unresponsive and you may see the following messages in the Syslog:

Syslog
The software driver for the Remote LAN Module (RLM) detected a problem: Unable to update SP network information at this time.

You can resolve the issue by rebooting the RLM from the CLI.

Log on using the CLI (SSH or console), then reboot the RLM.

CLI: rlm reboot

Wait for a while and verify the RLM is back online:

CLI: rlm status

The output of the command should report: Status: Online

I got this through the contact form. It's a jargon-free guide to computer and internet security. It provides a detailed explanation on how to properly secure your computer and internet experience, and best of all, it uses simple and understandable language, lowering the bar for everyone to secure themselves against malware, ransomware and other malicious attacks.

Although unsupported, it is possible to install Microsoft Security Essentials on a Windows Server 2012.

To do this, set the compatibility of the downloaded file to Windows 7, then start that file with the parameter /disableoslimit.

The installation goes without a problem, and as far as I can tell, there are no compatibility issues.
