Hi Technogeezer, 

thanks for your answer and your willingness to help me. Firstly, I don't intend to work with Windows 95 seriously. It was my second operating system (after Windows 3.1) and my son is interested in it, even some old games which operate with this system. I answer to both of your emails. 

I attach the vmx-file for your check and some screen pictures. Maybe the error is no access to a DHCP-Server because sometimes there was such an error notice. But I don't know how to correct. 

I used this site you indicated but also other ones. Many sites recommend to introduce a new protocol with Microsoft as Manufacturer and TCP/IP as a Protocoll. I have not enough knowledge with network connections. 

I have also established an internet by call connection which was common in those days. I prefer a LAN connection but is it possible to make (simulate) such a connection even nowadays ?

Within network  connections I have also an Ethernet virtualbox Host only Ethernet Adapter. Because sometimes I tried to check if it is possible to manage a problem in Virtualbox and then transform to VMWARE I tried also this. I hope there is no disturbance.  I hope there is also no disturbance between the internet connection of different vmware machines (Windows 95, Windows 98, ...). I have tried some vmware machines.

I attach the vmx-file (as a text file, otherwise it is not allowed) and a file with some screenshots. You can see also the Internet Explorer with the error notice. If you need more information.
