Testing a variable with the value of zero

Tonight, while working on my previous script, I ran into an interesting problem when testing the presence of a value. Consider this: PS C:\> [int]$IntValue0 = 0 PS C:\> [int]$IntValue1 = 1 PS C:\> [string]$StringValue0 = “0” PS C:\> [string]$StringValue1 = “1” PS C:\> $IntValue0 0 PS C:\> $IntValue1 1 PS C:\> If ($IntValue0) {…

PowerShell Null Routing Function

This week, while troubleshooting a networking problem for a customer, I wanted to limit or block network connectivity to some remote endpoints from a test workstation.  To accomplish this, I created a quick PowerShell function to null route the traffic (send it to an invalid/null next hop). You can copy/paste this and save it as…

Update: Dynamics 365 Testing Tool

Earlier today, I was notified that the Dynamics 365 network URLs page was updated, so I updated my Dynamics test tool. But then, I thought, what else could I put in it? Never one to leave well enough alone, I started tinkering.  The result: Updated network tests for crmdynint.com Updated network tests for passport.net endpoints…

Update: Create-LabUsers Tool

Just when you thought it couldn’t get more awesome. It has. By popular request, I have added a few new features (and fixed an annoyance).  First, the bug fix: -Count 1 Yes, it’s true. If you ran the Create-LabUsers script with -Count 1 with the -InflateMailboxes parameter, you’d run into an issue because of how…

How to find Stale(ish) Azure B2B Guest Accounts

If you are utilizing external, guest, or B2B users in your Office 365 or Azure environments, you may need a way to determine which objects haven’t been logged in or used in a while.  Azure AD doesn’t provide an easy way to view this information (really only having the refresh token time available).  This method…

Mail-enabling Guest Users or “How I made everyone show up in the Address Book”

So, today, I received an email from one of my esteemed colleagues asking how we could get B2B Azure AD tenant guests to show up in the Office 365 GAL.  I thought, “Yeah, that should be something that’s possible.  I mean, they have email addresses.” In a rare turn of events, it actually is as…

Update: AAD Connect Network and Name Resolution Test

Update: This tool has a new shortlink: http://aka.ms/aadnetwork Since the tool passed the 500 download mark a few weeks ago, I’ve started getting more questions (internal and external) about a few of the tests and checks.  So, I decided to update/refine them to hopefully provide better guidance. The big changes: Updated reporting method for TLS…

Report proxy addresses not in Accepted Domains

Like as the waves make towards the pebbled shore, so do our proxy addresses hasten to multiply. At least, that’s how it seems.  As is the organizational ebb and flow, business objectives change, new business units are spun up, old projects are turned down, and you may need to add or remove proxy addresses in…

Update to the Create-LabUsers tool – now, with bigger foo

Update: I’ve added a shortlink for this tool: http://aka.ms/createlabusers. In my quest to make the perfect tool for creating a realistic Lab Environment, I have added yet another feature, based on requests that I imagine people are making but have not yet told me about.  I’m going to go ahead and add ‘psychic’ to my…
