how to read physical memory on win NT/2k/XP ???

hi there !
i want to be able to read physical memory on win NT/2k/XP platforms...
right now, i can read that memory on these platforms, but when i try to read memory but ONLY on an administrator account...when i try to run it on a guest account or a limited account it simply pulls me out of my program with no message at all...
i have attached a small program to test reading the memory, and i hope that somebody can look at it and tell me if i am doing anything wrong, or what access should have the user to read the memory...i've tested the program on win2k...
thanx a lot, and here are the sources (in the attached file)

The user shouldn't have permission to write memory or read memory that doesn't belong to it. I don't really think that the administrator should have this permission either.

Put this code in a device driver, and launch it like a service, make and app that comunicate with your driver, and there you can read the memory regardless the user that's logged on

In order to read physical memory, you have to be in administrative account. Take the advice of jhad in using a device driver if you want to overcome permissions.

Go to http://www.internals.com/. They have the tool WinIO which is a driver implementing what you aare trying to accomplish.

Hope this will help you
