This is probably not related to the virtual Ubuntu Linux system but to the network configuration of the virtualization and/or the firewall configuration of the Windows host. Please also show the network mask on all machines.

Do you have some sort of route between the Windows systems and the Ubuntu Server? They are in completely different subnets so without a route they cannot see each other. I use the [Online Subnet Calculator](https://www.subnet-calculator.com/) to make sure my network for local is correct.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
