  • 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: 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: Two connectors; same cost; same number of hops to destination; message delivery will be load balanced across the two connectors?

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: The SubmissionServerOverrideList...

    Obviously we all know that Link State is going and E2K7 bases its routing decisions on your AD site topology. Generally I think this is a huge step forward but there will be occasions where our preferred AD site design is not the most efficient for routing emails. In that case the following might be...
