Sam mailed me with the question that made me shout out Aargh!
“We’re trying to configure Active Active cluster situation in Exchange 2003 but are having problems with poor performance when failing over. Can you advise please?”
Well the best advice I can give you is DON’T do it!
We do support Active Active in Exchange 2000 and Exchange 2003 but we DON’T recommend it. Read this KB article that’s been published recently, and go and deloy Active/Passive instead. Please…
