You should go back through the various App Notes from Atmel to read up on the usage of RESET pin during ISP. Looks to me like it is configured wrong.

Can u ellaborate? I looked at the application notes of atmel it says the reset is active low. While in at89s52 rst is active high. Do u mean I should put an inverter? I am using stk500 plugin in avr studio 4. Thanks for your response!
