When we run ColdFusion on our production server using a domain account, CFExecute no longer works. I've tested this using a batch file that simply makes a copy of a file. The error message returned is 'Access is denied'. The domain account has full control of all necessary locations.
We run ColdFusion on our development server using the domain account and it has no problem with CFExecute. We can also schedule tasks on our production server using the domain account without problems.
