Are the DOS batch files located in the moved folder, or are they located in the drive that was vacated by the moved folder. DOS batch files depend on the instruction set located within c:\winnt, ( if that is where NT is located ), and your environment needs to reflect that. Also, when you move a folder from one NTFS drive to another, you need to check that the permissions did not change on the folders that were moved. Remember: permissive rights flow down in the directory structure, if the root drive, or parent directory that you have moved the folder to has a different set of permissions, your original permissions are overwritten. It is possible that you don't have the right to execute files anymore. Another tip: the most restrictive rights take precedence, that is if Admin is set to have complete access, but the group everyone has no access, you might lock out admin becuase everyone has no access.
