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. ......

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 ......

Build Guides: Windows 2008 R2 Server

In this first part of the build guide series we look at building a Microsoft Windows 2008 R2 server. 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

Disabling IPv6
I often see that people want to disable IP v6 on their windows machine but instead of disabling it completly they uncheck the box on the network adaptor. Unfortunately that is not enough.... In general I would say "leave it enabled" but there are always specific cases where you want to disable it. The only products I would strongly advise against disabling it are the SBS products. For some reason disabling IP v6 on these boxes can cause massive issues in communications between the different applications ......

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 ......

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 ......
