I have run into a strange issue with trying to benchmark Exchange performance.I have Exchange 2003 SP2. There are content switches that forward the traffic to ISA (both in the DMZ) that send to one of two front end boxes. I can login from the inside (bypassing the content switches and ISA) and log directly in and all counters show 0 (MS Exchange Web Mail counters). I am trying to look at things like Authentications, Authentications per sec, Message Opens Total, Message Opens per sec.I do get stats when I look at IIS data (logon attempts/sec, etc.)I am stumped as to why I am not seeing any data....any help would be appreciated.Thanks!Matt
