Our default domain group policy has the screensaver timeout set to 900 seconds (15 minutes). We just installed a new software package and it requires a timeout of 15 minutes or it won't run - it wasn't running so we started to investigate. We found that the local machine policy in the registry had the timeout set for 30 minutes so we changed that as well to 15 minutes. The software package works for a day or two and then the timeout value changes back to 30 minutes so the package stops working. I don't know what is changing it - shouldn't the domain group policy override everything? Any ideas??
