Transition to Exchange 2007 from exchange 2003
In the lifespan of an organisation it’s messaging environment be transitioned to a newer version several times. Whilst this is not a complicated thing to do it does require some level of planning and thought. I’ll be addressing the transitioning from Exchange 2003 to 2007 from a fairly simple view here. Since the general outlines of the process are the same for nearly every situation there is no need for different detailed documents on this. We’ll be working with the following infrastructure in this ......

Troubleshooting for Microsoft Exchange
Exchange is a complex and large product which can have one thousand and one possible issues, one more obscure as the next. The purpose of this guide is to shed some light, where possible, to how things work in Exchange (and outlook), how they can break and how you should approach the issue at hand. Unfortunately it is very time consuming to create a complete troubleshooting guide where every dependency is explained in detail. But that is not the aim of this document anyways. What is the aim? Give ......

The information store service is stopped and will not start
Troubleshooting the information store service can be straightforward yet immensely complicated if you don’t know what is going on. For this reason I think it is important to know that there are 3 likely culprits that will cause your information store service to go down and refuse to come up: · Database problems · Active directory problems · Antivirus software Trying to work out which is the culprit can be hard, elimination is probably the easiest way to work through this… So let us get started! 1. ......

Troubleshooting incoming mail flow (or the lack thereof)
Usually you’ll get alerted to this issue with a call saying that users have not gotten any new email for a while. They will still be connected to Exchange in outlook, you can still log on to the OWA and, when looking at your hub servers, you can see that the all services are up and running (Note that it is possible the transport service could be stopped…). A number of reasons can exist as to why you are not getting any mail flow: · Your recipient polies are not configured correctly · The receive ......

Allowing internal services to relay through exchange
We all get those requests where there is a certain service that requires to send mails by using your company email server. Whilst an open relay is generally a way to get your domain blacklisted forever, allowing an internal relay is usually a necessity. By default Exchange is setup to deny relaying from any IP address, including your internal network. In this section I will show you how to allow relaying from your internal network. Exchange 2003: 1. Open the Exchange system manager 2. Expand the ......

Domain Naming Service
Consider this article on DNS a prequel to the upcoming ADDS series. After all, any active directory implementation requires DNS integration. So what is DNS? DNS is a highly reliable, hierarchal, distributed and scalable database used for name resolution and service location. So basically it translates friendly names (www.contoso.com) in to IP addresses (11.12.13.14) allowing clients to connect to resources in the infrastructure without memorising pesky IP numbers. History of DNS When the DoD initially ......

KB2644137: Windows Network Load Balancing does not work in an Exchange Server cluster
MS knowledge base article which is of interest: Consider the following scenario: You have multiple servers that are running Microsoft Exchange Server. The servers that are running Exchange Server are hosted in a VMware ESX environment. The servers that are running Exchange Server are part of a Windows Network Load Balancing cluster. Windows Network Load Balancing is configured to run in unicast mode. In this scenario, Windows Network Load Balancing may not work correctly. For example, network traffic ......

Whilst installing the basic operating system on a server is fairly straightforward it is as good a place as any to start as we lay the foundations for the rest of our infrastructure. In future parts of this series we will look at automating this install as much as possible, after all, we want our time spent on working with the awesome technologies available out there instead of installing serv

DAG's and reseeding
Sometimes you just wish Exchange would not act as a total baby! I worked on a case today which had 2 Exchange 2010 servers in a DAG with about 6 mailboxes, all in healthy status. All but one that is. This DataBaseCopy just would not come back into sync and was stuck in the eternal Resynchronizing loop from hell. So our client cried for help. First thing you would want to do is to get a status of the database by running get-mailboxdatabasecopystatus -id "databasename\servername" | fl. This should ......

Virtualized data center - Part Two: Hardware
Instead of making a list here of what requirements or needs for hardware hosts exist, I’ll make it plain and simple: CPU, memory and network links. Those are the most important things in a virtualization host and is all well documented in build guides across the internet. What I would to talk about is the following: Whitebox vs. Branded servers! Throughout the years I’ve been pretty much brainwashed (no kidding) that in a professional, production environment you only use “real” server hardware. And ......

A guideline to migrations: “All hands on deck!”
Welcome to this second instalment of the series! This series of articles is aimed at giving you a hold and a sort of “Best practices” to starting any kind of migrations. Whilst each technology or project has its quirks and traps most of the process you’ll need to go through is, roughly, the same. The second article will describe a so called “test run” or, as I like to call it, practicing with duds... Seeing as running a test system in the ground is not quite as disruptive as destroying an actual ......
