I have just spent a day and a half trying to figure out why one machine on my network couldn't access websites that were accessible to other machines on the same network.
The main symptom was that since late yesterday evening every time I tried to log onto this forum I got an error saying that www.donationcoder.com
doesn't exist. I panicked and in the end emailed Mouser to ask if there was anything I could do to help since the server seemed to be broken (memories of last years website hack sprang to mind). Having established that it was at my end and that my other computers actually did access donationcoder.com I set about searching for an answer. Now that I think of it i it does seem obvious to use another computer to check but given that my house is currently strewn with the remains of dead computers I had to cobble one together again to check the connection.
Having looked at the TCP/IP settings I noticed the DNS server had shifted from the automatic settings to fixed values (one of which was 184.108.40.206)
Everytime I tried to reset my DNS values or enter an IP for my Router it seemed to work except when Ioned the settings again they had been reset back to the bogus values.
I did a search on the IP causing the issue and found the following article:http://forums.spybot...hlight=220.127.116.11
This seems to be what happened to my system and having gone through the steps outlined my system is running normally again.
I really don't know how I managed to acquire this annoyance. I didn't download anything and run it yesterday evening so I can only assume it must have been a drive by problem on a site. If my experience can help anyone else it will have been a useful experience.
As it happens I haven't been spending money online today (so that is a relief) but do I now assume that all my passwords are compromised for sites that I visited - even though most of those sites are accessed via cookies?
