I need to know which users are writing/reading much data on the shares on my file server (windows 2003). My server is really slow from time to time and I need to know who is copiing or synchronizing his files on the server when the server experiences some slowness (CPU and memory are OK). Disk reads and writes are high (so is disk queue length), but I just don't know who are causing it.
Would like to use perfmon for that but didn't find the performance counters for that. If another tool is necessary, which one and how ?
