Syncronizing to Network Drive folder

[Mitya]

Hello.
I tried to syncronize local folder to a folder on Network Drive. It succeeded to copy "Files which exist on both sides" to Network Drive, but copying of "Files that exists only on the right" always cause an error: "Microsoft Windows Network: The name of local device is already in use" (it's my translation).

WinXP SP2, FC2009.02

Thank you
