  • Blog Post: NLB and the CAS\HUB role

    I’ve heard a couple of queries recently concerning Windows NLB and the CAS\HUB combined role.  The point is that you should use NLB to load balance network traffic and you can therefore effectively de-couple HUB from CAS.  For the Hub Transport server role (since Exchange 2007 SP1) the following...
  • Blog Post: Continuous Replication, Site Resilience & decision making processes...

    The ability to continue to provide a full service to your user community in the unlikely event of the loss of a datacentre is an increasingly common requirement. The use of Continuous Replication (CCR and SCR) with Exchange 2007 Service Pack 1 is an obvious choice in providing data availability and site...
  • Blog Post: Virtually a solution...

    Surely it's time to consider virtualising at least some of your new Exchange 2007 deployment?  Microsoft , VMWare and others now have some great solutions that on the face of it seem perfect for increasing the efficiency, scalability and uptime of your Exchange solution.  In my opinion yes...
  • Blog Post: How can the same email have two different sizes?

    If you look at the size of an email in OWA and then preview the same email in Outlook you'll see that the message size might not be the same....? The reason of course is that Outlook is displaying the message via MAPI (and TNEF) and it's connection to either an .ost or a mailbox role server. OWA makes...
  • Blog Post: More on ...Windows 2008 or Windows 2003?

    A blog on this same subject has just been posted to You Had Me At EHLO... and there are a few points that I'll add here which I didn't include in my original blog 'Windows 2008 or Windows 2003?' .  (...and I apologise for lifting these points directly from Scott's article.  There didn't seem...
  • Blog Post: Windows 2008 or Windows 2003?

    So you're about to deploy Exchange Server 2007 with Service Pack 1 and want to know which operating system to deploy.  There are a number of issues that you should be aware of when you are making this decision so I thought I would summarise a few points... The first has got to be the in-place upgrade...
  • Blog Post: Exchange 2007 Service Pack 1 on Windows 2008...?

    So now that Windows Server 2008 has been released what versions of Exchange Server can we run on it...?  Well the earliest version that is supported to run on W2K8 is Exchange Server 2007 with Service Pack 1.  It is not supported to run the RTM version of Exchange Server or indeed any previous...
  • Blog Post: High Availability in Exchange 2007

    Messaging is mission critical for most companies now and high availability is a major focus for any Exchange Server implementation. Exchange Server 2007 gives us some great options to enable us to achieve 'high availability' including LCR, CCR and, in SP1, SCR. ...but this is only really a part of the...
  • Blog Post: ServiceConnectionPoints

    Just been doing some reading on SCP's and how they are used by Exchange 2007. They are not something that I have come across before so thought I would share what I managed to put together... The 'service-connection-point' class is defined in the schema and the SCP objects published in AD contain information...
  • Blog Post: Designing for CAS and Site Resilience... [some more thoughts]

    Just carrying on from my previous blog .... Exchange 2007 has been designed to integrate even more closely with AD, a central part of which is AD sites. Therefore it is most logical to assume that your preferred design is that which also makes sense for other applications and services that use AD sites...
  • Blog Post: Designing for CAS and Site Resilience...

    One of the challenges that Exchange 2007 and the CAS role introduces is how to design for site resilience. Companies are going to want a solution that makes the most efficient use of the WAN, provides as seamless as possible a return to normal\full operation in the event of the loss of a single data...
