When creating a backup schedule in Windows Server 2003, if the destination target is on a NAS device, authentication may fail.
The following error will be recorded in aip.log:
WNetAddConnection2 failed, path \<host name><shared folder> , err 1203 Level=ERROR 
If this error occurs, set the DNS of the NIC used to 127.0.0.1.
Reboot the OS and re-create the schedule.
