Server 2008 R2 Robocopy Failure with Double Backslash "\\" in file path

Hi,

I am doing a large Robocopy for a customer of mine that is reading from a DVD source and copying across the WAN, potentially running for multiple months.  The RoboCopy is running as a scheduled task on Windows 2008 R2 (target) and copying from a Windows 2000 source.  I have kicked the process off twice, and each time it appears to function for a day or so and then begins to seemingly get stuck in a loop in which it is perpetually failing due to an attempt to append double backslashes "\\" to the file path.  I have been researching potential causes of the issue online and have come up empty.  Any assistance with this would be GREATLY appreciated.

Batch Script Robocopy Commands - 150 commands total, each using the same switches (note that /MT is not being used since it negates /NP and I have to verify the copy success with logfiles of a manageable size)

C:\Windows\System32\Robocopy.exe \\hqsa0400\ArchiveXtender\VolumeName F:\VolumeName /E /Z /R:15 /W:60 /NFL /NDL /NP /LOG:E:\JukeboxRobocopy\JukeboxOSM_Copy_VolumeName.log

Example of Errors:

2014/02/05 15:49:05 ERROR 123 (0x0000007B) Creating Destination Directory F:\VolumeName\20060130\\105413\
