I have a Windows XP PC.
It runs 24 hours per day, 7 days a week.
It does nothing else that running, every night, a (backup) script that does copy files from several production places to a external locally connected USB disk.
Regularly, the script fails during the simple copy operation of one file (not always failing on the same file, of course). The command is like "xcopy fromhere tothere" with some options.
The error message is (french translation to english) "insufficient resources to complete the requested service"
I then reboot the PC and it is okay for one week or two, until it happens again
How can I fix this definitively ?
