I have the same situation as this person:
"Have a Mac on 10.6.6 which is connected to a share on a Windows Server 2003. Majority of the time the file access is fine, but every now and then when deleting files, the progress bar will freeze, not do anything and lock the folder. The only way out of it is to reboot the mac.
Does anyone have any ideas please?"
Thanks for any ideas and support on this issue ...
