Office 365 Migration – When Do I Need to Use Third Party Tools?

This post may be late in coming, given that most smaller companies have already moved away from on-prem solutions to cloud based services for things like email and file sharing, but I feel like it’s important to stress some of the realities involved in migrating from on-prem to cloud systems. Particularly when migrating to Office 365.…

Exchange Server EMail Routing – Accepted Domains and Send Connectors

Exchange Server (And Exchange Online) can be a little confusing at times, particularly when we're dealing with mail routing. Internal mail routes are handled almost automatically (especially if you keep all your Exchange servers in the same AD Site, which I recommend), but how do you get it to route email to mail servers *outside* your organization? This post answers all the questions you might have about how to handle Special Mail Routing cases for Exchange.

DNS – An Introduction

Though you may not know it, DNS (Or Domain Name System) is probably the most used things on the Internet. In fact, you’re using it right now. For those who don’t know what DNS is or does, it is the system we use to translate Domain Names to IP Addresses.

The World Before DNS

Back in the early days of the Internet (And by early, I mean before it was even *called* the Internet), all of the computers that were connected to one another could only be reached by using a series of numbers.…

Hardening Microsoft Solutions from Attacks

Take a minute to go over this post from Dirk-jan Mollema. Go ahead and read it. I’ll wait…

Did you realize how scary that kind of attack is? As an IT guy who specializes in Exchange server and loves studying security, that article scared the snot out of me. Based on my experience with organizations of all sizes I can say with a good bit of authority that almost every Exchange organization out there is probably vulnerable to this attack.…

Data Encryption – How it Works (Part 1)


I’ve decided to start a short series of posts on data encryption, which is becoming an increasingly important subject in IT as government regulations and privacy concerns demand ever increasing levels of privacy and security.

In this series, I’ll try to cover the more confusing concepts in encryption, including the three main types of encryption systems used today; Private Key encryption, Public Key Encryption, and SSL/TLS encryption.…

Designing Infrastructure High Availability

IT people, for some reason, seem to have an affinity towards designing solutions that use “cool” features, even when those features aren’t really necessary. This tendency sometimes leads to good solutions, but a lot of times it ends up creating solutions that fall short of requirements or leave IT infrastructure with significant short-comings in any number of areas.…

Resolving the Internal and External DNS zone Dilemma with Pinpoint DNS

Here’s an interesting trick that might help you resolve some of your DNS management woes, particularly if you have a different Public and Private DNS zone in your environment. For instance, you have a domain name of whatever.com externally, but use whatever.local internally. When your DNS is set up like that, all attempts to access systems using the whatever.com domain name will default to using the external, Public IP addresses assigned in that DNS zone.…

ADFS or Password Sync: Which one do you use?

I’ve run into a number of people who get confused about this subject when trying to determine how to get their On-Prem accounts and Office 365 synced and working properly. Most often, people are making a comment somewhere that says, “Just use Password sync, it’s just as good and doesn’t require a server,” or something similar.…

What is a DNS SRV record?

If you’ve had to work with Active Directory or Exchange, there’s a good chance you’ve come across a feature of DNS called a SRV record. SRV records are an extremely important part of Active Directory (They are, in fact, the foundation of AD) and an optional part of Exchange Autodiscover. There are a lot of other applications that use SRV records to some degree or another (Lync/Skype for Business relies heavily on them, for instance).The question, though, is why SRV records are so important and what exactly do they do?…
