Thanks. That gets us part of the way there. At least I know what it is likely trying to do when you have the problem. Do you know what happened at that particular time [2013-05-31 14:04:07] on your machine? Did your IP address change, did you have network outage, did your ISP go down, did the pool go down? Did you delete windows in disgust and install linux to fix this?
I checked the router, and it didn't hang up or change IPs. The windows box has a static IP.
One other thing that might help - All machines mining on this particular internet connection would fail, not just this one. (They are all windows boxes)
That's the best I can tell you for now.
I haven't gone into the Linux world yet to mine because its been years, and I think I have been demoted to noob status again.
I probably should switch to linux though.
