Ok so I ran sfc /scannow 3 times, it reported no corruption each time. Tried dism with all the different options, that didn't find any faults either. Worked through all the proposed solutions in the Resolve network issues thread, none of it did the trick either. Most of it ran fine, but with netsh int ip reset and netcfg -d I ran into the same errors I copied in my previous post.

What's next?
