If that is the case, you should get the same error from all other scripts.</P><P>&nbsp;</P><P>Which is strange. One unlikely possibilities come to mind:</P><UL><LI>some windows/firewall/network settings overwrite the standard adress. I am no network expert, but you might try to troubleshooting with an AI. It usually works, but expect a lot of dead-ends.
