On one of my home systems, I went to update spybot s&d and noticed no updates. I checked, and there were no updates since early October.
The odd thing is that only update server listed was EON Australia.
So, I removed the program, downloaded from download.com and reinstalled, and no change there. The I removed it, deleted the entire install directory and reinstalled, searched the registry for anything with the name spybot. Nothing unusual found.
Finally found online.ini in the Updates dir, and it had only the EON server listed in the -Mirrors section, but that server is not serving up any updates. I manually edited it and moved the usual set of update servers out of -Mirrors.disabled and into -Mirrors to fix it.
Not sure how or why this happened, in a fresh install, but it was very odd.
By default, where does it download online.ini from? It seems to me that if it can't get a valid updated copy of online.ini from a known server that's working properly, a new user would unknowingly get the same behavior I've seen.
I've also seen no update servers in the list on this machine, then hit update and EON appears.
