Dear Duncan, thank you very much, that is it! Indeed, there was activated in my internet router the "telekom navigation help". When I am (or the system is) looking for an not existent url, this "help" opens its own website. After deactivation of telekom navigation help, the normal message (server not found) comes. I never gave attention to this "help", although it is bothering sometimes; now it is switched off in my residence. However, in Germany this problem probably frequently arises, therefor, it should be considered in the respective code for testing R after compilation.
