Is there a way of seeing how many open sessions there are in IIS6?

Question

I have a feeling we are being hit by very high traffic, how do I prove or disprove my theory?

Answer 2

Check your IIS log files, they log every single request that comes into the server. By default, they should be located in C:\inetpub\logs\LogFiles\, however, your server administrator may have changed that
