As Was early mentioned about the only other possibility is that there is a proxy setting somewhere that Calibre is picking up and trying to use. However you seemed pretty confident that this was not the case.

XP SP3 embedded software firewall is disabled.
I have no software firewall running.
I have no antivirus running.
I have no proxy settings in InternetExplorer8. No LAN settings either. It's all left blank not configured for any particular configuration.
IE8 works perfectly just like all other programs connecting on the 'net, the Winsock stack has no issues.
There are no viruses in the system either. Manually running non-resident antimalware scanners gives no infections result.
I don't know how Calibre estabilishes internet connection at source code level, thru which APIs, but if it's using InternetExplorer settings to do it then I don't understand how comes it's the only program unable to connect given that IE8 itself is running fine too.
