Sure, here are a few things to check:
1. Did you verify that this particular file was included in your 10 GB file copy?
2. And its linked target? (Probably something like "f:\arscache1\<somenumber>\CBA\DOC\2FAAI")
3. Did you use the proper flags in robocopy so that the link file (I assume) was indeed copied
as a link? Robocopy default is to copy the link TARGET instead of the actual link.
4. Also, even if it is a link, the link may be "dead". You can check this by right-clicking on the link file and check if it has a target file path or not (compare with the same file on your windows 2012 server)
EDIT:
5. Of course, also check the access settings for your OD user account against this folder structure. It is a beach
in Windows, not like in the Unixes where you can just run "chmod sumthng" a couple o'times and it's done.
Hope this helps!
