Here's what I am doing and what started ~12/10. For years, I've used a FreeNAS server as the primary filer server for ~6 spreadsheets here at home that are updated from various computers, as convenient. Daily, I use a scheduled DOS .bat file to xcopy the directory for all files with the archive bit set & reset the bit to various other file servers. On 12/10, the .bat file stopped copying the files even though they had later file dates. I started looking at what was happening & found Win7 shell & GUI showed the archive bit not set. And, when I tried to set it from either, it did not change. I then tried the same on another 2 FreeNAS servers, also running post-12/10 versions. I got a mix of either no change with no error or no change with admin permission required. Windows show file ower as FN/guest with everyone having full access. In trying to figure out what's happens, I've tried changing volume permissions from the FN GUI to various things. None made a difference. I posted here before filing a bug to see if anyone could replicate the issue. Hope this helps folks understand what I am seeing.
