Stop .DS_Store file creation by Mac OS X
Mac OS X has an annoying habit of littering network shares with .DS_Store (Desktop Services Store) files. If you only use Mac OS X and other Unix based systems you may never actually see them, but in mixed environments they can become a bit of a nuisance. There is nothing critical stored in .DS_Store files, just Finder specific settings, such as icons size and location, view settings, etc.
To prevent .DS_Store from being created on network shares, run following command in terminal.
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
To revert changes and resume .DS_Store file creation run:
defaults write com.apple.desktopservices DSDontWriteNetworkStores false
