A LITTLE BACKGROUND:
I Have an Intel Atom based home server running Win7 Pro x64. I am in the process of moving all my DVD content onto this server for use with my Boxee Box. I have 2 desktops in the home running Win7 Ult x64, which I use for transcoding. I also have a MacBook Pro on my network. I have Intel Gigabit Ethernet cards on the 3 windows PC's, all hardwired.
I have a network file share established on my Atom server, which I am accessing on my Boxee Box. I am able to access the share without issue until........I transfer files from any of my computers to the network share. Within 30 seconds of the start of the file transfer, my network share will show as disconnected. I noticed this issue occurred on my MacBook Pro as well, because after adding new movies, I can not access the share from My MacBook Pro either, however, Windows PC's are unaffected.
After doing a little research from the OSX viewpoint rather than the Boxee viewpoint, I found an article that outlined a registry fix for Windows 7 when this occurred with a Linux box. Below is the link, and I have summarized the fix as well.
Set the following registry key to ’1′:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
and set the following registry key to ’3′:
I only applied this fix tonight, but have been unable to reproduce the issue through the previously mentioned means. Hopefully this helps you as well!
