How to check which CAS server did user (outlook) hit among the group of CAS servers (Exchange 2013 CU3) behind F5 load ba

Hi Shaik ,

In my environment also we are using the F5 load balancers ,If i wanted to check which user is connecting to which cas server then i need to contact the person who is handling the F5 device.

Like you i have also searched for the same query before six months.Finally what i found is given below.

Basically we can use the netstat commands to find out the client connectivity to the cas servers .If we run the commands on the cas server ,we will not be getting the client ip address on the netstat output instead we will be getting the ip address of the F5 device.

But on the F5 device we can able to see which client is connecting to which cas server by using some com

Hi SAH,

as you may have implemented your load balancing as recommended (without using persistence), running netstat does not provide good data.

Please check your CAS IISLog (usually on C:\inetpub\Logs and choose your web servers subdir) and filter for your clients credentials in the user property (you can read the log easily by using Excel).

So you can just sort the requests by date, and you will receive the servers that responded.
