Windows USB Install Error 0x80070026
KB ID 0001485 Problem Now physical servers don’t really come with DVD drives any more, Im forever deploying Windows, ESX, or some other Linux OS via a bootable USB drive. I generally use Unerbootin, and just point it at the .iso file and away we go, which I did this week when trying to deploy Window Server 2016. However when I did that, this happened; Windows cannot open the required file {Drive}:\Sources\install.wim. Make sure...
ASDM on Windows 10: ‘Cannot find Javaw.exe?’
KB ID 0001478 Problem Windows 10 machine, (with Latest Java installed), while attempting to launch the ASDM you see; Windows cannot find ‘javaw.exe’. Make sure you typed the name correctly, and then try again. Solution I should have fixed this a lot quicker than I did, because the error message was a lot more descriptive in older versions of Windows and the ASDM! This is the same problem seen on Windows 8. You still need...
Cisco AnyConnect With Server 2016 NPAS (RADIUS) Different Groups
KB ID 0001474 Problem A few years ago I replaced a firewall that was setup like this, and while it took me a while to work out what was going on, I remember thinking it was an elegant solution. Fast forward to today, and I’m now working with the guy who set it up! (Kudos to Paul White). So when I had a client with a similar requirement, I sat down fired up the lab, and documented it. What was used; Windows 10 Remote Client...
SMB1 Is Dead? (Unfortunately Not Yet)
KB ID 0001461 Problem I recently did a migration for an engineering company, about a week later I got an email from them to say, “We have a new Windows 10 PC, and it can’t connect to the ‘N’ Drive?” I asked them to send me a screenshot, the error was; You can’t connect to the file share because it’s not secure.

Windows ‘Always On’ VPN Part 2 (NPS, RAS, and Clients)
KB ID 0001403 Problem Back in Part One, we setup the AD (Groups,) and the Certificate services that will knit everything together. Now we need to configure an NPS server that acts as a RADIUS server for our remote clients, And a RAS Server that our remote clients will connect to. Step1: Network Setup Microsoft have an alarming habit of telling you to connect DMZ assets to the LAN. In their defence I’ve seen some documentation...
Remotely Log Users Off From CLI / PowerShell
KB ID 0001401 Problem I’ve not had to do this since the days we got “The terminal server has exceeded the maximum number of allowed connections” errors. Now thankfully Windows Server tells us who is logged on so we can ‘ask politely’ before we boot them off! Today though, my user session got all messed up, and I needed to kick ‘myself’ off remotely, (and have a fresh session.) Solution From a...
Windows ‘Always On’ VPN Part 1 (Domain and PKI)
KB ID 0001399 Problem Always On VPN was a bit of a misnomer when it was released, as it was only really ‘on’ when a user logged on. So when comparing it with ‘Direct Access’ it didn’t have the capacity to ‘Manage Out’. With the release of Windows 10 (1709) this has been rectified with ‘Device Tunnels’, (more on that later). The solution uses RAS, NAP (NPS), and PKI (Certificate...

KB ID 0001396 Problem Source Path Too Long The source file name(s) are larger than is supported by the file system. Try moving to a location which has a shorter path name, or try renaming to shorter name(s) before attempting this operation. “Have you come across a problem deleting folders with long filenames?” I got asked this question twice in the first week at a new job. In a former role my colleague did a lot of work in...
