Ahead of Patch Tuesday, a cautionary tale

Microsoft has officially considered Home windows 10 model 2004 as “ready for business,” but I’d argue it continue to desires a little bit much more support to be completely ready for customers. With this month’s Patch Tuesday upon us, here’s an case in point of what I indicate. It involves mysterious NAS troubles, some sleuthing, and a workaround — all of which clearly show how troublesome updates can be at times.

This circumstance involves one AskWoody subscriber who explained to me recently that every single time he upgraded to Home windows 10 2004 the set up would break his laptop or computer. Like any great geek who refuses to permit technologies get the ideal of me, I emailed him back and requested for far more facts about what was acquiring broken when he upgraded. Turns out, he would get rid of obtain to mapped drives on his NAS (community connected storage) devices. While he tried to remap the drives, they would are unsuccessful, forcing him to roll again to  Windows 10 1909 — exactly where almost everything would perform.

Short term, this was an excellent workaround. Lengthy expression, however, this will only get the job done till May possibly with Home windows 10 Property and Experienced edition. That’s when support for safety updates for 1909 end. (Business and Education and learning versions get an supplemental yr of aid after that.) Obviously, we had to occur up with a remedy before long.

The NAS units affected were being a LinkStation and a TerraStation from Buffalo Tech. The moment he stated Buffalo Tech, I knew the root dilemma:  SMB v1.

SMB, or Server Concept Block, is the standard file-sharing technologies that is been made use of for a long time. It’s the glue, both in Home windows networks as perfectly as Linux-primarily based equipment, that lets you to share and help you save data files. But it is also subject matter to assaults and so Microsoft has been building a concerted energy to clear away SMBv1 as a native technology. Its weaknesses have been exploited by attackers for years, and as Ed Bott pointed out far more than four decades ago, the planet has largely moved on to SMBv2 and SMBv3. Even so, some NAS buyers continue to count on that system.

In fact, if you put in Home windows 10 1709 or later in a clear put in, SMBv1 is not enabled at all. If you have upgraded from older versions of Home windows 7 or 10, SMBv1 will be enabled — but if it’s not made use of in 15 times, the procedure routinely turns it off. If you reenable it again, it will appear again and ought to continue being functioning. So, I 1st instructed that Michael reenable SMBv1 to reestablish connectivity to the devices.
