Achieving High Availability with Exchange 2003
Microsoft IT has released a white paper detailing how we achieve 99.99% availability with Exchange 2003, clusters and Service level Agreements and the Best Practice Analyzer that Paul Bowden is talking about at a TechNet event in February.
Its an interesting read, and gives an insight into how we manage our Exchange environment internally, with lots of useful links.
I'll be delivering a presentation on Thursday on how Microsoft IT implements Messaging security if you have some free time and want to get inside away from this blustery British weather and into a nice warm auditorium!
