How to monitor Internal & External Ek27 OWA traffic
It may sound like a very basic question but its something I need some clarity on and any help/suggestion from the forum will be greatly appreciated.
We have exchange 2007 SP1 setup.
I got took over this exchange env. with my limited knowledge of exchange and no dcoumentation on this implementation.
Having said that, I want to understand how the internal and external OWA traffic is flowing. As far as external is concerned, I can see that its happening through ISA and I can see the web rules directing the external traffic to the CAS box.
However I am not sure on how to check how the internal clients are connecting to OWA.
Hope thsi question makes some sense. I can provide more details
Cheers!

you need to use performance monitor and add the msexchange OWA counters

Endital my Friend !!!
I am using Perfmon and here is the reason of confusion:
We have 2 CAS boxes (Also having the role of HUB) for the NA domain.
We also have a physical Load balancer (F5)
We have ISA 2006 for external OWA traffic
On ISA rule, I see that the firewall policy is kinda configured to allow traffic from anywhere to one Specific CAS box lets say CAS01
Which ideally should be sent to the NLB which then distributes the load to CAS 01 & 02
Having said that...
I am checking the perfmon for MSExchange OWA - Current user counter for these CAS boxes and can see traffic on both the boxes for OWA.
So where is my confusion??
I understand that external traffic is being redirected to CAS01 from ISA (Which Ideally should be load balanced and is my next corrective action for thsi environment)
Now What I wanted to understand is how is the internal traffic is being routed to these boxes, where to look out for that info.
I do see a firewall rule in ISA ,"Local to CAS" it says from Local Host to CAS 01 & CAS 02
Is this what controlling teh internal traffic??
