We are having a lot of problems from Mac OS X when connected to a Windows 2008 R2 file server.
Typically we are having a lot of issues deleting files and directories where the progress bar stops moving half way through the delete, renaming folders is a constant problem where it says we have do not have permission to change directory names (even though checking the permissions we do have permission).
We used to run Windows 2003 server and Mac OS X with no problems at all, since switching to 2008 R2 it has been a constant headache.
Things we have tried so far are deleting the .ds_store files within all directories on the server and also prevented the Macs creating a .ds_store file by running "defaults write com.apple.desktopservices DSDontWriteNetworkStores true" from the command line.
These have helped a little, but it still far from being perfect or even usable in a production environment, does any body have any suggestions which may solve this problem as it is really causing me a headache!!
