howto://add the Telnet client to Windows 10

Just a quick reminder to myself on how to enable the Telnet Client in Windows 10, since I always seem to forget.

  1. Open an administrative command prompt.
  2. Run this command
    dism /online /enable-feature /featurename:telnetclient
  3. Done. It will be immediately available, even in existing, non-admin command prompts you already have open.

If you want to test it out, try this! telnet://

30 second movie review of Spectral

If you’re a Netflix subscriber, you’ve probably seen Spectral as one of your “Top Picks.” It’s actually a Universal production with some real acting talent, great special effects, and decent writing that, for whatever reason, Universal opted not to distribute. So Netflix picked it up.

There’s a fun mix of special forces action, science fiction, and ghost story all mixed in together, and well worth a rainy Saturday afternoon. Check out the trailer, then add it to your watchlist.

howto://set a Windows Server 2016 Hyper-V host to use SNTP for time sync

set your server to sync to NTP by running these commands.

w32tm /config /syncfromflags:MANUAL / /reliable:yes /update

net stop w32time && net start w32time

So I’m in the process of (re)setting up my lab, using a pair of multi-proc servers running Hyper-V to host my VMs. These will be member servers, which would normally get their time from a PDC in their domain. Of course, DCs normally need to get their time from a reliable time source, but as VMs, mine would get their time from the host servers on which they run. I could have changed the DCs of course, but instead opted to make those physical systems more reliable. That’s what this post is all about.

Miss me?

and we’re back. After some unavoidable hosting issues ended the previous incarnation of retrohack, I seriously, considered just letting it go. I mean, I wasn’t spending that much time on it, hadn’t in years, had gone months between posts, and really didn’t think anyone cared. Then two things happened. The first was that I got an email from someone who actually missed the site, and who said some very nice things about it. Then, I needed to enable stealth mode on Skype again, and couldn’t remember how to do it. Thank the gods for, which seems to have a copy of most of my old content. So, as time and interest allows, I will try to recreate some of the old posts from the website formerly known as, and who knows, maybe I will even add some new ones. Stay tuned, or not, as you see fit :-). And if there’s actually a post you’d like to see, use the contact form to let me know and I will try to nudge it up to the front of the queue.
