Hi Straagal
You say 'Both computers are via router, the laptop is wireless and the "sick" one by cable...?'
Do you mean that the only problem computer that you have is the cable (network) computer? And otherwise, network was okay?
May help some for Services entry identified earlier - Wired AutoConfig (Dot3svc) - Stopped - if possible, was reset to Automatic and began as such with the whole network. So perhaps, need to adjust configuration utility (msconfig) and maybe router as well, I dunno, but just to sort the Dot3svc issue anyway.
