When a company with an existing Exchange Server organization begins adding Exchange 2007 servers to the mix, it is tempting to remove the old Exchange 2003 servers immediately upon completion of the migration process. However, it has been my experience that immediately decommissioning legacy servers is a big mistake. In this article, I will explain…

A lot of Exchange administrators are surprised to learn that in most cases a new Exchange Server 2007 deployment is not able to send mail to the outside world until the administrator does some additional configuration.  The reason for this is that unless you have installed an Edge transport server, and created an Edge subscription,…

If you have been using Exchange Server for a while, then you probably remember when Microsoft introduced ActiveSync policies in Exchange Server 2003 SP2.  The policies that were available in that version of Exchange Server were a good start, but there were a bit lacking.  For starters, you only have the option of creating a…

The Light Weight Directory Services, or AD LDS, has been around in one form or another for quite a few years now. In Windows Server 2003, this service was called the Active Directory Application partition, or ADAM. Being that the service’s new name is the Lightweight Directory Service, I hate to describe the service as…

In my first article in this series on creating lightweight directory services, I explained that the Lightweight Directory Service (AD LDS) had replaced Active Directory Application Mode in Windows Server 2008. I talk about some real world examples of how AD LDS is used. In this article, I want to finish off the series by…

They sit on top of the host operating system, and all of the virtual machine’s hardware calls are passed through the host operating system, which manages the server’s…

If you’re considering bringing Windows Server 2008 onto your network, then one of the decisions that you will eventually have to make is how you plan to integrate this new operating system into your network.  In the vast majority of cases, Windows Server 2008 domain controllers are simply added to existing domains, or some of…

As someone who spends a lot of time traveling, I have always thought that OWA was pretty much the greatest thing since sliced bread. In the hands of a user though, OWA can present a serious security risk. You just never know when a user could potentially disclose sensitive information by opening a file attachment…

In the first part of this article series, I gave you a general description of the options that are available to you for controlling the way that users are allowed to access message attachments through OWA. In this article, I want to continue the discussion by giving you some more specific information on how to…

In the previous article in this series, I talked about the importance of removing the routing group connectors prior to removing the last legacy Exchange Server from an organization. In this article, I want to conclude the series by showing you how to remove a routing group connector, and how to redirect the Recipient Update…

One of the biggest architectural changes in Windows Server 2008 is the inclusion of IPv6. IPv6 has been a part of Windows since Windows 2000, but Windows Server 2008 is the first version of Windows to enable IPv6 by default. Furthermore, The transport stack has been completely redesigned so that IPv6 and IPv4 are able…
