The encountered problem can be related to the machine definition or the job owner credentials needed to be added in autosys_secure.
The recommended solution was to add the following attribute to the machine definition:
opsys : windows
The problem maybe resolved by adding opsys: windows attribute to the machine definition.
To list the machine definition you can run the command
autorep -m <machine_name> -q
If the problem persists confirm that the job owner is defined in autosys_secure and not locked by operating system. Only for windows agents jobs requires users and passwords are defined in autosys_secure.
To list the job definition
autorep -J <job> -q
To lists all users with passwords from the command line run
autosys_secure -s -host ALL
