*Deep movie announcer voice* In a world where Email must go through arises a new hero! Only he could fully apply the changes made to receive connectors without destroying the WORLD!
Okay, not really. But I wrote a script that will run through all of the Exchange servers in an environment and restart the transport servers on each.…
In my last post, we covered the basic concepts of cloud computing. This time, we’ll be diving down a little deeper into the cloud to cover the actual structure that most cloud environments use to operate. There are a lot of differences between cloud providers, but they all use very similar hardware and network designs to get things done.…
Exchange server maintenance requires some specific steps in 2013+. There is no specific maintenance mode, as in previous versions, but you can complete a few actions to take a server out of production. You will need to drain the SMTP queues on the server, tag the services as unavailable, then disable transport entirely. Each step needs to have some rest time, so that is built into the script.…
Due to some copyright violations and the need to copy protect my blog posts as a result, I’ve moved my PowerShell stuff to my Microsoft Technet Gallery so people can use them without writing out the whole thing.
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.…
As I mentioned in an earlier post, email encryption is a sticky thing. In a perfect world, everyone would have Opportunistic TLS enabled and all mail traffic would be automatically encrypted with STARTTLS encryption, which is a fantastic method of ensuring security of messages “in transit”. But some messages need to be encrypted “at rest” due to security policies or regulations.…
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.…
