I have no scripts but with "Localhost" it works. And it seems to be case
sensitive. But why on some pcs works without?

Thanks
Alberto

Look for script stoppers, from anti-virus software or software firewalls.

In some cases people have reported making it work using "Localhost" as the
second argument to CreateObject.
