When running an image location check for about 60 computers at the same time, and all with the same UNC path (for both folder and volume path), why do 75% return "Bad Path" while others succeed?
Running the check again will show that computers that succeed a second ago now return "Bad Path" and other that failed before now succeed. Nothing has changed.
If the test is run in group of less that 30 computer, then all succeed.
This is due to a limitation of the target device. If the device is a windows machine, then you may be hitting a maximum number of concurrent connections limit.This has been seen with various NAS devices - they cannot handle many connections at once, in fact the Lacie NAS boxes have a hard limit of 5 concurrent connections.
Stagger the tests to confirm that all the settings are correct, and ensure that you dont ask all the machines to hit that box at the same time in future.
