1. Open the Terminal.
2. Type:

defaults write com.apple.desktopservices DSDontWriteNetworkStores true

3. Press Return.
4. Restart the computer.

now you'll no longer fill the windows file server with annoying .ds_store files. you'll no longer unknowingly commit hundreds of irrelevent .ds_store files to your subversion repository mounted over webdav with auto-versioning. rejoice.
