Are they on the same network?

Since this is a problem in a windows VM (probably in a Debian host?),
this is barely applicable to the list, but I'll bite...
Sounds like general network gremlins... A couple of things that spring
to mind:
(1) Can the windows boxes ping e.g. 8.8.8.8 ? If not, then network
connectivity is likely broken...
(2) Can the windows boxes resolve names? E.g. ping www.google.com ?
If not, then DNS resolution is borked...
(3) IP address collisions: If two systems on the same network have the
same IP address, then you will get inconsistent results... To see
whether a box suffers from this, obtain it's IP address and
disconnect it from the network. If the IP address is still
pingable (or just arping'able), then this is a red flag...
Hope this helps
