I am currently experiencing the same issue here with DSS v6 (6.0up13.8101.4023 64bit) with Roaming Profiles.

All goes well, except 'desktop.ini' files.

It appears that it is impossible to write a file with that name to a DSS share.
I tried copying, copying hidden files, renaming existing files, creating new file, but all to no avail

Please help me out: am I missing something here?
Is it a Samba configuration that I should (and could?) change in order to make it work?

Pretty annoying having users facing the same failure message every time...
