The GPO Startup scripts works fine on other machine but not for another half of the machine. gpresult show that GPO was there. I ran RSOP and it show that the Startup script was there but it was never executed. There nothing on application error or anything related to the failed execution in the event viewer.

I have set to Allow slow network connection too but it did not help for the startup script to execute.

Permission read/execute granted to Domain Computers & Authenticated Users

Other GPO settings works except Startup Script did not execute. The scripts works fine as other machine which success without any issue except some machine.

I need help to sort this out as it troubles me where another half of the machine did not execute the script at all. It was all WIndows 7.
