We have several windows 2008 IIS7 web servers setup. They all use FTP 7.5 to allow multiple users access to their individual website folders.
This works in principle however we experience lots of file locking issues. For example:
User ftp's in to site, attempts to delete some old files to replace with new versions (e.g a new wordpress plugin for example), receives file permissions error (varies slightly on ftp client, but invariable they are file locked / no permissions errors).
If an admin then browses to that file on the actual server in question they will be unable to delete the file as well. The file will eventually be deleted in time (unsure how long but certainly longer than 10 mins) or if we restart the ftp service, or the iis service.
We have tried turning off caching and indexing on the website folders with no resolution.
thanks for any help.
