Have you installed any plugins lately? In perticular a renderfarm plugin? are you running buildbot / graphicall builds? if graphicall build, have they included a renderfarm patch? have you tried restoring to factory settings?
i have tried several different builds now…
and all new builds try to connect to the internet…
trying to find out why… this is without enabling any addons.
and running the builds as portable.
Thats strange… but its worth to take a look at it. If this happens in build bots i would say its a problem with your firewall, i dont think such thing could happen in trunk blender.
But maybe you could sniff it with wireshark to see what information blender tries to send, and to whom.
I suppose Blender is searching for network hard drives or something.
Edit: Ah, you already mentioned that. Strange enough I couldn’t find any references in the source code. Maybe it’s code library or python? I wonder if this happens on other operating systems…
