In this new blog post series I’ll be looking at (normally a selection of 3) cool articles, news and other blog posts that I find interesting during the day. For this week we have PowerShell tricks, a detailed article on securing the Windows Firewall and an (old but very interesting) write up on the woes of network administrators when everything goes wrong.
PowerShell tricks: Splatting
New to me (always learning!) this trick allows you to populate the parameters for a PowerShell cmdlet in a table (makes for much neater formatting) to then pass into the cmdlet as a single object.
Endpoint Isolation with the Windows Firewall
The Windows Firewall may seem like a bit of a beast from time to time but this article makes some great points on how to build out a set of secure policies that can apply to pretty much any environment.
All systems down
A true disaster story – quite old (2003) but really worth a read to see what lessons you can take home.
Bit of a crazy issue when deploying a new Ruckus wireless network – in first suspecting an issue with the controller software or perhaps some kind of access control list blocking traffic it turns out that the default Windows Firewall rule for allowing NPS traffic is broken in some fashion.
Having tried this (and it working fine) on Windows Server 2012 R2/2016 it really does appear to be isolated to Server 2019.
Discovering this came about with a few traffic captures combined with the wonderful NTRadPing tool. The fix is to manually create the rule, see the screenshots below on how to do this.
In this final post we’ll cover the Configuration of Network Settings and setup of Remote Management for a Hyper-V 2012 R2 Server which will be managed from a Windows 10 Enterprise PC.
There are quite a few steps to go through for this part of the configuration of the Hyper-V deployment however a number of these steps can be applied to the servers through Group Policy and thus removing the need to repeat them again.
First up we will configure the management network adapter and domain join the Hyper-V host…
