If you shutdown/reboot a windows 2003 server with that slave installed as
service the master still thinks the slave is online.
This is related to 2566.

After the reboot the service on the windows2003 is not started. So the slave is
still offline. But the master acts if it is online.
The master is not up to date on the status of the slaves.

When you execute a task on that slave you get:
