Question

Computer networks

Hello!
Having problems doing the lab
There is an internal network that has three virtual machines
1. Windows server 2012
2. Windows 10
3. Scanner-BC (as far as I understand it is based on Astra Linux)
Here are the settings for Windows server 2012

Here are the settings for Windows 10

Here Scanner settings

I tried to ping all three machines - everything is fine with Windows server 2012 and Windows 10, but not with the Scanner, neither the Scanner does not ping, nor both Windows do not ping

Answer 1

Check Selinux/Firewalld have been configured/disabled

Answer 2

That's it, the problem is solved) The
usual reinstallation of the Scanner helped, now everyone pings everyone
