When running a image location check for about 60 computer at the same time, and all with the same UNC path (for both folder and volume path). 75% return "Bad Path" while other succeed.
Running the check again will show that computers that succeed a second ago now return "Bad Path" and other that failed before nowsucceed. 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 can not 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.
