Guys I was dying trying to find something that could let me take the details of the XML data of a specific event so I could then use it to, say, send an email with just that data. Here's how to do that: Here's all the code right away: # Get the event you want and then format that event in XML Format $event = Get-WinEvent -MaxEvents 1 -FilterHashtable @{logname="Security"; id=5379} $event = [xml]$event.ToXml() # Drill down into the XML. In this example we're getting Event > EventData … [Read more...] about PowerShell – Parsing and creating variables from Events in Event Logs using XML
OWA and ECP Web Errors after SSL Cert Update – Error 2001
If you just updated your SSL Cert (and it looks as though it is correctly installed) but both OWA and ECP have broken, you're going to need to associate the roles with the SSL Cert.

Creating your first Apache Airflow User
I've learned a few things while working with Apache Airflow: Apache Airflow is awesome. Apache Airflow documentation sucks. If you were able to launch Airflow and run the webserver, you'll notice you're being told: WARNING: No user yet created, use flask fab command to do it. Here's that command: FLASK_APP=airflow.www.app flask fab create-admin Follow the prompts and once complete you'll be able to log in with that user. … [Read more...] about Creating your first Apache Airflow User
Windows 10 Hyper-V Ubuntu Can’t Connnect when Enhanced Session is Enabled – Blue Screen
I've recently been toying around with the Quick Create in Windows 10 Hyper-V and I noticed that I couldn't connect once the VM was created if I chose to connect using an Enhanced Session. As it turns out, if you enable auto login during the setup of the Ubuntu VM it will not let you remotely connect using any option you have. It just gives you a blue screen. Make sure this option is not set to auto: If you have already set that setting to Log in automatically and you want to … [Read more...] about Windows 10 Hyper-V Ubuntu Can’t Connnect when Enhanced Session is Enabled – Blue Screen
The “do something to all machines” PowerShell Script
On a domain? You can do something to all machines on a domain with this quick little script here.

Updating NTP Servers in vCenter 6.7
Time servers can be a pain. In this case, once completing a vCenter upgrade from 6.5 to 6.7, I noticed the time wasn't syncing. It took a bit to find where to update the NTP servers and enable the NTP service for vCenter. Here's how to do that: Log into vCenter and head to Menu > Administration > Deployment > System Configuration. Click on the LOGIN button for the vCenter you'd like to administer. This will take you to the Appliance settings. Log into the Appliance Head to … [Read more...] about Updating NTP Servers in vCenter 6.7

Powershell script won’t run portion requiring Excel in Scheduled Task
Some of the scripting I've recently done requires Excel to be launched (non interactively) on a domain controller to gather usernames and whatnot. For some reason, the entire script would work perfectly besides the portion that requires Excel. I could run the script as an admin in ISE and it would work, but not via the Task Scheduler. Here's the fix: Create these two folders on your server: C:\Windows\System32\config\systemprofile\Desktop … [Read more...] about Powershell script won’t run portion requiring Excel in Scheduled Task
Exchange: Export a list of all public facing distribution groups
Public facing isn't the right term here. It simply means that the authentication requirement to send mail to the distro has been disabled to give anyone anywhere the ability to send an email to it. That makes it publicly accessible. If you want a list of all of the distribution groups that have the authentication requirement disabled you can use this little one-liner. Open Exchange Management Shell as an Administrator and type the following: Get-DistributionGroup | ? … [Read more...] about Exchange: Export a list of all public facing distribution groups
