Windows 2008 R2 (64-bit) Permissions Issues?

I need some help to migrate from Windows 2000 to Windows 2008 Server. There are some issue with configuration after upgrade. I am quiet happy to see new things on Windows Server. I am trying to work with permission stuff right now before going for upgrades. I know there will be tons of thing which will stop working and with no means I can fix that easily. There are some scheduled task which are configured on the 2003 server. But does after migration those will stay active in 2008. I am performing some test on a test machine and found that I have to run each task manually. The task has some issue with auto launch. Also want to discuss about Crystal Reports here which is hosted on IIS. The user when go on web page the viewer shows rpt files. Some files which are associated with sql are not reflecting.

The task fail due to console permission issue. You must allow it to run through console. You can reschedule the task and it would give you option to work on the same. Also do not forget to apply gpo settings and then see whether all is working fine or not.
