With the new Windows 1909 update we got some nice fixes of crucial issues with Windows 10, but also got a few new bugs. For me, probably the most annoying one is that with every boot all of my 20 network drives are marked as offline. Now the fix is easy, just pop them open with your explorer, and the notification (could not reconnect all network drives) goes away, but doing that for all of them is a bit annoying. Now Microsoft is aware of the issue and has marked it to be fixed within the next updates, but until then here is a small script that will find and open (as well as close) those drives for you and make the notification go away.

Just save the bellow script as ANYTHING.bat save it to your PC and either add it to your startup menu or just leave it on your desktop to click when you need to.

    Probably the “Home Folder” you are mentioning is not designated as a drive letter in this script. Just replace the findstr “Z:” and “OfflineNetDrives[!OfflineNetDrives_cnt!]=Z:” part of the script with the name of your device (the example is if it’s called Z:

    Hope it helps!
