ADFS: Deploy Active Directory Federation Services
KB ID 0001140 Problem The actual configuration of ADFS depends largely on what you intend to do with it. Here I’m using it to broker connections from my Microsoft Web Application Proxy. This article is just to ‘join the dots’ and covers just the installation of the role itself. Solution Before you Start: Make sure you have a certificate ready to use for ADFS. I typically use a wildcard cert for this, it’s...

Cant Copy a Group Policy Object
KB ID 0001543 Problem Was asked this this morning, why couldn’t someone ‘Copy’ a Group Policy Object (GPO)? Solution At first I was confused, (I made the same mistake they had), look at what I’m trying to copy? It’s not a Group Policy Object, its a ‘Link’ to a GPO. (Note: There’s a shortcut arrow!’) Locate the actual GPO and you can copy it! Related Articles, References, Credits,...
Test Port Connectivity Through a Firewall
KB ID 0001541 Problem Test Port Connectivity: I was asked if I had a test Exchange server that someone could test TCP port 587 to this morning.

This time it didn’t work, so I found a small application that you can use for this very purpose. How to Test Port Connectivity Test...

KB ID 0001539 Problem Remotely connecting to Windows is easy we’ve had RDP since Windows NT4, (yes I’m that old). But what if you want to remote connect to a mac? Well that has ‘Screen Sharing’ built in, (which it pretty much the same, but it uses VNC). If you’re unfamiliar with VNC, (Virtual Network Computing,) you can install it on both Windows and Linux. Normally you need a client, (to connect with)...
