Docker on Windows 2016

Posted on by

Docker is a tool that allows to deploy applications software in a “sandbox” (called container) to run on the host operating system (in this case Windows 2016, but also Windows 10 Professional or Enterprise, several Linux versions and MacOsx).

Nowaday the industry standard today is to use virtual machines to run software applications that provide full process isolation.

Att.: Process isolation means that a problem in the host operating system hardly can affect the software running in the guest operating system, and vice-versa.

This isolation, however, comes at great cost because of the computational overhead spent virtualizing hardware for a guest OS.

Containers take a different approach that provide almost the same level of the isolation of virtual machines, but at a fraction of the computing power and using more efficiently the underlying system and resources. Continue reading →

Windows 10: Mapping Drives via GPO Script Failing

Posted on by

Some days ago I’ve upgraded some pc’s to Windows 10.
After that we’ve verified that using old-legacy software we cannot get any mapped drive (via GPO Script) using folder/file explorer.
If we link this disk on desktop, and try to use it, we get an error.
The only solution is to enable the “Linked Connections”.
1) In Registry Editor, locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
2) Right-click Configuration, click New, and then click DWORD (32-bit) Value. Name the new registry entry as EnableLinkedConnections.
3) Double-click the EnableLinkedConnections registry entry and type 1 in the Value data field: then click OK.
4) Exit Registry Editor, and then restart the computer.

Windows 2003: Lost network connectivity

Windows95WowYesterday I was working on an old windows 2003 server. I know: Windows 2003 is beyond End-Of-Life and it is dangerous to use it in production environment, but here in genoa we are famous for not wasting anything, and also the server is used in a “sandbox” and run an old legacy software not available for later windows versions.

When I was copying some files server has stopped all connectivity.
– Attempting to ping any ip on the dedicated LAN returns “destination host unavailable”.
– The NIC & Driver looks fine in device manager
– Ethernet connection in Network Properties shows status as Connected
– Link light and activity light are active on NIC
– Using arp -a I can see that the ip-MAC address association works ! Continue reading →
