Back on Ubuntu, after a year on Windows 10.

Ironically, Windows 10 runs much better inside a VirtualBox VM on top of Ubuntu, than it did on bare metal (same laptop!)...

Anyone else here using LogMeIn for remote support?

Have you experienced, that in the middle of a session you get disconnected from the clients desktop in the Technician Console, then connected to a strange desktop (not at all related to your own, nor the clients infrastructure)?

Had this happen to me today (twice), remote controlling two different client desktops in separate sessions (newly created 6-digit pin for each session).

I could even remote control the strange desktop for at bit, before it was disconnected and I got reconnected to the original client desktop.

This can't be a password breach, because then the Technician Console would be taken over by a rogue user (if he had the password), since there's only one seat-license - this is the other way around - I'm on the same Technician Console the whole time and session is the same (initiated by the 6-digit pin) - it's just the viewed desktop that got "swapped out" for a few seconds, then it "swapped back".

Anyone who knows what can cause the System process in Windows 10 to eat 25-30% CPU constantly?

It happens a while after startup, if I restart it goes away but comes again later.

Also having long waits when unlocking the screen when it's locked, takes forever. But login is a snap, from the first login after the PC is started.

I'm out of ideas, tried removing 3rd party antivirus (Bitdefender), tried sfc scan.

You learn something new all the time (apparently) - today I discovered a quirk in the NetNames DNS admin panel, one that isn't documented anywhere and something you apparently should "just know about" or accept to be blissfully clueless.

Here goes:

When you add a CNAME (or any other address), you have to remember to put a period (.) after the address - example:

Wrong: Host name: "autodiscover.contoso.com" Points to: "autodiscover.outlook.com"

Right: Host name: "autodiscover.contoso.com." Points to: "autodiscover.outlook.com."

If you don't the DNS provider adds the current domain to the end of the address!

So - even if it looks correct in the admin interface ("autodiscover.outlook.com" is displayed) the result is actually "autodiscover.outlook.com.contoso.com"!!!

How f*cked up is that?!!!

...I wonder why Exchange Online kept telling me my CNAME's were wrong, when trying to enable DKIM, even though they looked right...

Hint: Use dnschecker.org to see the propagation of your records and if they look right (to the world)...

I have a laptop with Windows 10 behaving really strange, regarding disk volumes.

It's a brand new HP ProBook 440 G5, which comes with a 256 GB Intel M.2 NVMe - I installed an extra 8 GB RAM and a 1 TB Samsung EVO 850 in the HDD bay - the latter being the troublemaker.

Windows finds the disk alright, I select to use GPT and make a simple volume of all the space - works.

I can write files and copy to from the new volume BUT if I go and restart the laptop I can no longer access the volume, when I log back in!

It starts out saying the Recycle Bin is corrupt and should be deleted, then it can't do it - accessing the volume I get Access Denied. I can't take over the ownership, can't do anything - except delete the volume, remake it - then it works until I restart again - What the h....?!!!

I'm curious as to what is the best practice for setting up a Smart Home that works?

Just dipping my toes in the Google Home / Smart Home thing - got a Google Home Mini in October and just got a Philips Hue bridge. Even though Google Home isn't available officially here in Denmark and I can only speak to it English it's still exciting.

I started out with my own account as primary, then added my wife and sons accounts for voice match - it recognizes them alright, but my wife can't play our Spotify collaborative playlist (started by me) with christmas songs - only I can do that - even though we've all set Spotify as default music service?

Also - when I set up Philips Hue I used my own account (easiest, since I could just "Sign in with Google").

But it got me thinking - wouldn't it be better to make a new Google account for the house, then make that the primary account on the Google Home and also use that account for the Philips Hue account?

Since now I have to use my own Google account to sign in to the Hue app on my wife and sons phones - that's a bit messy. Also - I will be the only one able to make IFTTT recipies, they should really be tied to a neutral account, that everyone can use?

It's still a little confusing, how to make the best and most "tight" setup...

Projecting to other devices with Windows 10 - what can make it slow (low frame rate)?

I've just installed a 75" touchscreen in a meeting room - tested with a Microsoft Wireless Display Adapter (v1) - everything is more or less fluid, but projecting to an Intel NUC7i5 running WIndows 10 is jerky and low framerate.

I've tried changing resolution from 4K to FullHD on the NUC - no change.

It's all good and well using the Microsoft adapter, but I want to use the NUC, so I can host a Skype for Business meeting with screensharing, so everyone in the room can project their screen and other participants in the meeting (across the Skype connection) can see it as well - using the adapter only works for local meetings.

The NUC is on wired LAN (Gigabit), the PC's projecting to it is on WiFi (AC 1750 Mbps) on an AP barely 5 meters away. Both AP and the NUC are connected to the same switch.

Question - What is the propagation time of settings in Exchange Online Protection?

Added an IP to be whitelisted in the Connection Filter in EOP, but it still appears it hasn't taken?

This is related to the question I posted earlier regarding Postfix relay and O365 Exchange Online - apparently some very nitty-gritty security gateways other people use (cough-Ironport-cough) do RDNS lookups, and I made a mistake in the VIP on our firewall, so I was actually sending out on our default interface IP, instead of the NAT'ed IP I had designated.

I've added the missing IP now in Connection Filter, but external mails still bounce - it's like our tenant SMTP still doesn't know we've whitelisted the public IP?
