Very High Disk Queue Length

I have a little bit of a mystery that I need some help to figure out.

I have a Server 2003 file server that suddenly is being hit very hard and need to figure out who/what is generating the I/O. This is ONLY a file server, no extra services like SQL, etc. The bottom line is that Disk Queue length is spiking to the the 60-80 mark, and the users connected to the shares are being disconnected because the server is clearly running out of resources and being overwhelmed.

I've already almost swapped out all of the hardware in the box, and at this point am looking for some type of software that will just show me the file activity that's going on between the clients and the shares. Obviously I can look at the Open Files list to see whats actually open, but that isn't telling me what is pounding on the disks. I'm looking for something simple and low level, like filemon for example, but filemon only shows local disk activity, not activity that's coming in and out over the network redirector.

You might try Diskuse.exe which is part of the Windows Server 2003 Resource Kit alongside standard perfmon.

perfmon has successfully showed me that there IS and I/O problem, however I need a tool to show me where all this extra I/O is coming from. diskuse generates reports according to usage, however I need something similar to filemon to actually see what files are getting hit.

Unfortunately, there is not much out there free for a Windows system.  Quest has a Windows Monitoring tool that has a trial download that you can use.  I have used their Spotlight product trials in the past and they are pretty in depth.
