Hello ant Thank's for your answers. I just started my Computer and also reinstalled MBARW. I have one Installation with no Problems her in my Network. But just this Installation was done before we changed something in the Firewall. I think it is possible that something is blocked now. Wich port do I have to open for the Installation (80, 443, or another one) The PC we installed it has the same configuration regarding the security Software. So I think this would not be the reason for my Problems. (Sorry about my English it seems to be a little bit rusty) Kind regards Uwe
