The problem:
MS Windows 10 virtual machine cannot browse for network shares on the server.
The Hardware:
PC = HP Z200 Workstation.
NICs = Intel ® 82578DM Gigabit Network Connection or Intel ® Gigabit CT Desktop Adaptor.
Software:
Virtualization platform = VirtualBox 6.0 (Version 6.0.6r128413) and at least one previous version.
Host OS = Windows 10 Enterprise 2016 LTSB Version 1607 (OS Build 14393.2848).
VM = Windows 10 Enterprise LTSC Version 1809 (OS Build 17763.107)
Server = Linux NethServer release 7.6.1810 (final) Kernel release 3.10.0-957.10.1.el7.x86_64
Background:
The following points are noted:
I have been using this general setup for some time with no issues.
When the problem happened I made sure all updates were applied (MS WIndows host, MS WIndows VM and Nethserver server). VirtualBox was upgraded to the latest version.
I can ping from the VM to the server.
I can join the VM to the domain.
In the GUI, using \ \Nethserver\software does not work whereas it does from the host (applies to any other share as well).
Using \ \192.168.0.254\software does not work whereas it does from the host.
Net use z: \ \Nethserver\software does not work.
Both host LAN cards have been used to no avail.
I have reinstalled the VM from the ISO.
I have a classroom of HP Z200 PCs – the problem is on all of them. Please note though that the W10 hosts OSs are fine – accessing shares is good.
However I have just tested an older PC (Core 2 Duo running Windows 8.1) and using the host machine (no VM) it suffers from the same problem.
Any ideas would be greatly appreciated!
Thanks in anticipation.
