php-win2k error in apache as isapi module

What is going wrong and where it is going wrong I dont know? I was trying my first script with sessions. Before testing the script, I did following change in php.ini in winnt\system32 register_globals=Off The code I was trying was: ----- <?php $os = "BSD"; session_register($os); $name = "devon"; $devon = "my name"; session_register($name); //registers variable "devon" with value "my name" ?> ----- Immediately I got the error the following error a Critical Error Button Message: The Instruction at "0x006c956c" referenced memory at "0x8b2b43b1:. The memory could not be "read". Click OK to terminate the program. Click Cancel to debug the problem. Please help me where have I gone wrong: either in modifying php.ini or choosing php as apache module or anything else in configuration. __________________________________________________ Do you Yahoo!?
