Hi Francois,
The issue is when it run on the test bot.
This patch removed all tests and traces around CoCreateInstance. https://newtestbot.winehq.org/JobDetails.pl?Key=4949&log_201=1#k201
Its timing out. I've seen this on Linux when mixing native dpnsvr.exe and builtin dpnet.dll due to the missing callback in dpnet.dll (not a windows issue). If dpnsvr uses the local address instead of the loopback then this cause the timeout.
Would it be possible to test windows 8 without the firewall enabled?
It's going to be hard to get patches accepted if win8 keeps failing.
Best Regards Alistair Leslie-Hughes
