There is a pattern in Web Service\Current Connections counter that can give you information about potentially blocked users, as described in this Technet article:

Chapter 5 - Monitoring and Tuning Your Server
http://technet.microsoft.com/en-us/library/bb742410.aspx

A curve in the graph of the Current Connections counter on any IIS 5.0 service performance object that reaches a high value and then forms a plateau. This pattern often indicates that additional connections are being blocked or rejected.


I recognize that this is an old reference, but I believe that the monitoring described is still valid.  I have an old frame of reference, since I haven't worried about type of monitoring in a while.  This is something that is good to keep current.

It looks like it is still current for 6.0:

I am looking for the blocked count (counter) not just the visual in graph.

OK, I searched my memory banks, and I came across "Total Blocked Async I/O Requests", but if you look here, it is no longer a valid counter for IIS 6:

No, I haven't found a replacement for that counter.  I would request attention for this question.  You might want to request additional Windows Server zones, to see if a network administrator might know the answer.
