What is a Tabletop Exercise?
Often you'll hear someone mention a "table top exercise" - what does that mean? They're not talking about a table talk apple pie - that's for sure! A tabletop exercise is a play on words, it's not really an exercise nor is conducted (in today's world) at a tabletop.

Why is IT Asset Management Important?
Переглядів 238Рік тому
What comes to mind when you think of the term asset? Usually it's a tangible piece of hardware. Many times when I request an asset inventory from a client, that is what they hand me. A spreadsheet filled with serial numbers, model numbers, purchase dates and assignments. Those are all great items to have documented, however, hardware isn't the only inventory you should keep. You also need to th...

Hi, your video worked very well for me. My question is: How can I generate another certificate for another group of computers? I have a second SSID and I don't want all the computers to connect through the same certificate.
Thsnks!
Everything is fine for me until I'm trying to change schema operations master. The change button is greyed out. I've tried running MMC snap-in from both source and target DC (picking target DC first of course), greyed out on both tries. It's Windows Server 2019 Standard on both DCs. ADD: My domain user was not member of schema admins group. After adding and logout/login, I was able to transfer this role as well.
Good video but I would take it down and re-upload it correctly. The Demo worked because he has misconfigured the NPS Server in a way that he added extra configurations which are completely ignored by the NPS Server. There are two conditions on the NPS Server and the logic is: a) If someone is trying to access a Wireless network and b) if someone is member of the Group "Lab_Radius_Auth" then Grant access. Both these conditions are met on his Demo laptop that is why the laptop gets access to the Wi-Fi network. It's a nice video but there are mistakes. The Certificates and GPO that he configured are completely ignored cause he only configured 2 Conditions in the NPS Server which are met regardless of the random GPO and Certificates he created. Even if the GPO did not apply to the laptop, the laptop would still get access to the Wi-Fi network.
Great stuff, but how do you allow local admin account to access for trouble shooting in the event there are domain issues?
Thank you sir for the great video I have a query, If I follow this tutorial how could I achieve the requirement to setup Radius server for Wireless Users Authentication. I need to set up RADIUS for our Wireless Access Points (APs). The challenge I'm facing is RADIUS server is separate machine and I need guidance on how to properly link the AD with the RADIUS server which the requirement is to create on Separate machine. Could anyone help me understand the additional steps involved in configuring RADIUS server and how to integrate the AD and RADIUS? (Does the Radius Server could be the Domain User and then it integrate as well? What would be the configuration at AD and Radius for integration) I would appreciate a detailed breakdown of the additional configurations needed on both ends. If you have any documents, guidelines, or videos that could walk me through the process, that would be immensely helpful. I’ve been unable to find the right resources so far.
Thankyou. I got my fans running quieter. Is there a way to make them slightly less? I'm sure my server was running significantly quieter than it was now, but I accidentally did something that made the fans run crazy loud. After doing this, they are running at 35%. Could I get this down to 25 or less?
thanks/this helped!
Great video I was doing it correctly! I like you like to separate GPOs out as it maintains order and uniformity, thanks so much for the video!
Great video and explanation, subscribed!
Hello do you by any chance know why the policy is grey out for me. I was able to get to security settings an all but it has a padlock Im connected as the admin
Who else is watching this in 2024 after CrowdStrike about took down the world lol
Is there anyway to create a GPO that I can apply to users instead of computers?
Great video, thank you for posting.
I spent HOURS scratching my head on why I could not get VLANS working on OPNsense via Hyper-V. After isolating and troubleshooting each individual component, I figured that the OPNsense VM was not seeing the tagging. I almost ended up going bare metal, thankfully I saw your video and that saved me! THANKS SO MUCH!!!
Me too. Holy hell. Sad part is I was running OPNsense on a little micro firewall a few weeks ago, so I sorta forgot I installed it to run on my Hyper-V server. Lol. Thanks to the original poster - Alex - for enlightening me.
Still works.. thanks so much!
your video still like a spotlight, thanks!
Great Video!
great video thanks to him I just configured authorization via RADIUS I have one question - can I configure a WIFI network for guests without a Unifi gateway?
that is a very informative video ,thank you
did i miss something on the post configuration RAS configuration....is it just a wizard and follow it for the DirectAccess and VPN?
Thank you
Very good video. I followed it but I get this error: The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server.
Thanks for the video. The information about "Adding a User" in Duo's online account is somewhat confusing. I am setting this up on my personal Windows 11 laptop so that it prompts me to validate via the DUO app on my phone that it is really me who is logging in.
you are simply the best, TY
Thank you
Great tips and edu . thanks a lot
I know this is late but I'm new to the server world. Can someone help me. Do I need to set up the idrac and have it plugged in with its one Rj45 to do this? It's not working and says something along the likes that it can't reach it or no response. Please I beg you all any info would be great!
I'm trying to reinstall a server on my VM. I'm following the steps in your video. Hopefully, I'll be able to. Thank you for the video.
Great video! Thanks!
Very well done! Thanks for the good work.
I am glad you finally shaved your head. I am going bald as well its my time soon, RIP
thanks man!!! cheers to your work.
thank you for make this so simple and not over complicated
i have a problem with internet connection through vmware. ive set my vmware on host only and already coupled the server domain to an client. the only thing is that when i make a scope en look at the ipv4 its down. this is because i dont have internet and idk how to fix that at all. can anyone help me with this?
It's huge PITA! I hate the way O365 goes about setting this up
Thank you.
New system admin here, glad I found your channel
You isntall RAD and not configure it. Why its installed?
Thank you for giving a clear explanation. I read about it else where. They kept beating around the bush without saying what it is. Thanks again.
Great Video, thanks a lot...

I had an issue transferring the Schema role. I had to run a PowerShell command for that last one. The Role numbers are here so I excluded 0,1,2,4. The command to transfer roles from Powershell is below. 0 PDCEmulator 1 RIDMaster 2 InfrastructureMaster 3 SchemaMaster 4 DomainNamingMaster Move-ADDirectoryServerOperationMasterRole -Identity "ServerName" -OperationMasterRole 0,1,2,3,4
does it need to be mapped to a physical adapter? does it not work with a team?
Thanks for sharing good knowledge, good explain, keep spreading and sharing knowledge, Thanks Again
FYI, you do not need the remote access role installed. Just NPS. I am not sure why every guide is adding this unnecessary step.
Thanks! its it posible tu use sshpass in order to execute some comands like reboot?
What happens if there is not enough room in the flash for both firmwares?
Great job
does this apply to non dell drives bing in the system as well?
Yes
