Exe executed in a windows2000 machine

I need a VB program that counts, on a single Win2000 machine,the number of times that an EXE has run and by what user.

(or)

here is what you will probably have to do. Need a program which will create the log- save it to SQL, CSV, MDB, I don't care at this point. The program to log will start as a service- it will begin logging at the time of the system's boot. The exe's to log are user defined in a master list- they could be one exe or hundreds. start with some simple ones like notepad.exe or explorer.exe. it needs to count the number of times that a particular exe as been executed and by what user
