Hi,
Thanks for reporting the problem. I have been able to track down the cause of the failure, and it will be fixed in our next update.
In the meantime, it should be possible to work around the issue, by mapping the network path to a drive letter.
If you right-click on My Computer in the Windows Explorer, it should show an option called, "Map Network Drive..."
This should allow you to map a share like "\\Xw4400\F\" to a single drive letter, such as Z:. Then, use the drive letter in the Ingest destination, instead of the \\Xw4400 path.
Sorry for the inconvenience.
Hope this helps,
Bill
