[plug] Samba issues

[Hani Jabr]

Hi,

I haven't had that particular issue, but there were a lot of changes to CIFS between Windows 2003 and Windows today. A lot of it was bug fixes that seemed to change behaviour quite radically. 

I would try upgrading Samba to V4, either the latest Debian package or download the latest stable version and compiling it yourself. As always, you may want to try firing up a new VM running Debian 7 to test on first (nfs share dir to VM, then samba share it to Windows).

Unfortunately (or fortunately as it might seem) we've landed a new job, and I've had to move to Windows 7 as the latest version of Revit won't install in S2k3.

With the move to Windows 7, I intermittently get permissions errors when re-saving files which causes things to require manual intervention and stuffs up my "start it, go to bed and wake up with it done" workflow.

It *is* driving me insane and has resulted in me copying entire directories from the server to the VM, running the automation and copying it back (and hitting retry until the recalcitrant drawings can be overwritten).
