Super Boring IT Article #2: DNS part 1

DNS Haiku

By John Lim, CTO

I ripped off the above haiku from reddit.com/r/sysadmin. The reason I love it and all other sysadmins love it is that it’s TRUE.

Specifically, in an Active Directory environment, DNS is a yuuuuge deal but in our regular day to day internet life, DNS is STILL a yuuuuuuuge deal.

Machine Learning: Cybersecurity’s Most Promising Weapon

Machine Learning

By Russ Levanway, CEO

I recently returned from an HTG Peer Group conference where I met with a number of my colleagues from around the country to discuss trends in technology and business. Over the course of the conference, a very hot topic emerged: the benefits and liabilities of encryption.

Not that long ago, most traffic traveled across the internet unencrypted and relatively easy to intercept. Today, in order to secure traffic, the right side of the law has been using more and more encryption methods. For instance, when you visit a website and enter your credit card number, the page is always encrypted; when you enter a username and password, that’s also always encrypted. You will typically notice this via the yellow padlock next to the web URL in your internet browser.

The Internet has a protocol for packaging information and transmission of said information, and that Internet Protocol (IP) requires addressing. When you go to Google.com, Facebook.com, or Netflix.com, all of those names resolve to one or many IP addresses on the backend and gets your applications to pull data from those servers. All of these providers has unique public IPs that only belongs to them.

RDS Servers, Hosted Exchange + Outlook Cached Exchange Mode

Ruby Nahal, Engineer By Ruby Nahal, Senior Engineer

With the rise of hosted exchange services like Office 365, it has increasingly become a challenge to preserve Outlook performance on RDS servers. Back in the day, you could only run Outlook in online mode on a remote desktop server. This was for the better because back then exchange deployments were local so we didn’t want RDS server storage filled up with unnecessary OST files.

Ruby Nahal, Engineer By Ruby Nahal, Senior Engineer

Domain Controllers and Recovery

The USN rollback issue may not be an everyday problem for some organizations, but as an Engineer at a Managed Service Provider (MSP), I have seen my fair share of the condition. The problem is global – and is caused from restores of domain controllers in multi-DC environments since the introduction of Active Directory (AD).

Change Control: Getting a Handle on Chaos

Ruby Nahal, Engineer By Ruby Nahal, Senior Engineer

As Network Admins, we are all guilty of making a change without taking the time to document that has come back and hurt us. Even more frustrating, is when you get stuck working on an issue due to someone else’s lack of documentation. I, myself, have worked on several issues where undoing undocumented changes took several hours to revert.

Hence, Change Control occupies a very special place in my heart. It saves you a ton of heartache, forces you to pre-think the changes you are making, the consequences, possible roll back plans (very important) and the entities and processes that may be impacted by the change.

Exchange Database Repair

Ruby Nahal, Engineer By Ruby Nahal, Senior Engineer

As tech admins, we have all dealt with the extreme fickleness of Exchange servers for database integrity at some point in our careers. Whether it is a good old dirty shutdown of Exchange services or storage block corruption, Exchange can be left in an inconsistent state ranging in symptoms from inaccessible mailboxes to complete database unmounted condition. Since email is the core communication path for most businesses, downtime can lead to the loss of money and time.
