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 ......

Cleaning up whitespace in exchange
During the lifespan of an Exchange server a database can become very, very large in the size it takes on the disk, much larger than the space used by the mailboxes that reside in the database. This is because whilst mailbox sizes will expand and shrink according to their data usage, the Exchange database only expands. Any space freed up by deletes in mailboxes or even the removal of a mailbox all together become whitespace in the database file. In the worst case you could have 40 GB of mailboxes ......

Recovery storage groups
As you might, or not, be aware off there is no item level based recovery in Exchange that is natively supported by Microsoft. So to perform recoveries we need the recovery storage group (captain obvious). The purpose of this is to mount the database you want to recover from on the Exchange server and use exmerge to merge the data you are recovering into the active database. An RSG will not be accessible to users and you can only create one at a time. Exchange 2003: 1. Open Exchange system manager ......

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 ......

New users do not show up in outlook when in cached mode
A fairly common (and annoying) problem which seems to like to popup after migrations, yet not unsolvable. The key issue here is that there are new users added to the directory but they are not showing up in outlook. Now, if you are like most organisations then outlook will be operating in cached mode. So log in to OWA and test if you can see the new users there. I’m giving it a 99% chance that you will (and if you don’t you have a serious problem at hand!) The reason you are not seeing these new ......

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 ......

Reseeding the passive node of a DAG/CCR
Running a CCR or DAG is a great way to have a server resilient database. Relying on an asynchronous copy of the log files (Each log file gets copied over only when the store has released it) it copies over the log files from the active node to the passive node so it can be played in to the passive nodes database. But whilst being a great failover solution both solution are also quite high-maintenance, CCR more so than a DAG. Running in to a situation where the CCR or DAG is down because of to many ......

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 ......

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 ......

Troubleshooting exchange web services
Since exchange versions from 2007 and up put more emphasis on the webservices for use in the distribution of the offline address book, out of office, the scheduling assistant and autodiscover (a.k.a outlook connectivity to exchange) the correct configuration of the virtual directories and IIS components is the main key to a healthy exchange environment. It is for this reason that I have compiled a quick reference as to how these components should be configured in order to function properly and so ......

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 ......

Article: ADAM Troubleshooting
Initial troubleshooting As always, one of the first things to check is the event viewer to see if an event was generated detailing the error. Additionally check the %windir%\debug for the adamsetup.log and adamuninstall.log (this last one is only created during the uninstall process). These two logs will tell you where the setup is failing and what should be checked. It also pays to know that setup errors are written to the registry. If you cannot find the following key there was no failure as the ......

Article: Troubleshooting the information store service
Alot of calls I get are related to the information store service of the exchange server not starting. Since troubleshooting why this services does not start is often related to alot of stress (after all, your users and managers will be pounding your door as they cannot access their email) it is always handy to have some reference as to where you can start and what direction it can take. This is my basic modus operandi so feel free to give suggestions on how to improve it :). First of all you need ......
