Dbcopy errors Windows -> Windows

I'm trying to use dbcopy to create restore areas. My PO's are GW 7.0.3 on Windows , and my restore areas are on another Windows sever.

It seems that open files are not being copied. The errors I see in the logs are:
Source file user0dh.db found in ngwguard.db as user0dh.db
Error: Unable to open source file k:\ofuser\user0dh.db (8201) errno (5)
Error: Return Code (8201) processing k:\ofuser\user0dh.db

Other user files in the same directory copy fine. I have the same problem with msg files.

Isn't dbcopy supposed to be able to copy open files?
Is there some Windows setting I'm missing?
