If you want to see all the allocate "pool" resrouces then you will need to use the command "poolmon" which is included with Windows XP onwards.....run this command from a command prompt to see that is taking up all your paged and non-paged pool resources.
If you get the error....
Query pooltags failed (returned: c0000002)
Did you remember to enable pool tagging with gflags.exe and reboot?
The you need to:
1. Click on Start
2. Choose Run
3. In the run box enter "gflags" in the box
4. Place a tick in the box labelled "Enable Tool Tagging"
