Help me get the gremlins turning my PC's on please :)

Hi all,

Obligatory long time listener first time caller intro

I run a gaming cafe with 25 PC's and as you can imagine this involves a lot of updates over various applications and games. All the PC's are running Windows 10 1903 build. I have a cache system setup on a hyper-v box to deal with steam, blizzard, epic and windows updates which has been an absolute lifesaver.

We have cafe software which manages pc time, remote desktop, shut down/start up, member accounts and things like that. Worth mentioning that since the cafe software installed a particular update we have not been able to initiate remote start up (absolutely nothing changed on the PC's as far as configuration goes WoL still enabled in bios and on network adapter), which might seem like a small thing but since I tend to do a lot of managing from home it is definitely a spanner in the works.

We have been open two years and up until recently have never really had the need to setup a local domain to manage the PC's as people have generally been pretty good with not installing crap that they shouldn't and changing things around. I decided to setup another VM with windows server 2016 and add all the PC's so that I can configure group policy, handle updates, issue remote start up and general make life easier stuff. I haven't had experience with windows server prior to this but I am self taught and a fast learner so I figured why not.

I got the box up and running last week and I have all the PC's joined to the domain and I am still in the process of configuring things, however, I have a slight issue and it's somewhat annoying given the cost of electricity and all. The PC's will not stay off when they are shut down (shut down not put into sleep mode). I'll turn them all off at once then one by one at random times they will turn back on. I've run out of search terms to put into google trying to figure this out.

I would really appreciate some help troubleshooting this, I understand that by throwing windows server into the mix that this might make it not a windows 10 problem and I accept that my post may get deleted because of this, I do ask the powers that be to please not delete it if at all possible :)

Apologies for the wall of text and if any more info is needed I'm happy to provide what I can.

Cheers!

Thanks so much for the quick reply!

Just one question before I try these out and pardon my ignorance, but wouldn't disabling magic packet remove my ability to remote start the PC's?

Cheers :)

Okay so I disabled the wake timers with no result. Unfortunately turning off the magic packet is not an option as I need to be able to turn the PC's on remotely on demand.
