Hey all, new guy with a weird network issue I just can't resolve

I'll try to keep this as short as possible so it doesn't bore y'all to death! New build on this machine, and everything is working fantastic but SMB sharing. I've read dozens of posts in the last few days and tried every powershell script, command line command and trick I could come up with but it just won't do what I need it to do!!! Here's where its weird...

My pc will not see any other pc on my network, regardless of whether its a win 7, 10 or 11 machine (yep, built a quick machine with a different win11 version, 22h2 just to test this out), this is via SMB sharing and no password protection at all just to see if it will see anything. It wouldn't be so bad if nobody else could see this machine either, but they DO!!! Every, single, machine sees this pc's shared drives, can open files, copy, delete, save and anything else you can do on the share drive. It works incredibly well too! Fast transfers from one pc to this one, no crashing or anything else whatsoever.

I've looked through all of the windows defender firewall inbound and outbound rules, hell, I've even turned on the ones that were off and turned off the ones that were on with no luck.

I'm at a loss at this point and just don't know where to turn. I even asked my buddy who's a senior network tech for our local power company to take a look and he couldn't find anything that is out of order.

I've tried disabling defender too, just to see if that's what is causing it, and I'm still not convinced its not the culprit but it does seem to be off (at least that's what's being reported from Microsoft).

Now, there's one other important note to post here, and that's the OS version. It is based on Win11 LTSC, modded by Windows X-lite (win11 , I'm using the optimum 24h2 version right now). I'd like to say that its a great build, because it really is fast and clean with zero microsoft garbage, but the network thing is a no-go at this point. If I could contact the builder of this os, I would, but it seems he has no contact info anywhere at all! I've even tried contacting him on his youtube channel but no replies.

Hopefully someone here can offer some guidance on getting this working! I'd even be willing to remove all network components and reinstall that if you think that would work, but there is a TON of networking stuff in win11 and I don't know where I'd even start.

Thanks for any help you can offer!
Chris

Have you tried this in PowerShell?

Yep, checked that, SMB1 is good!



Also, SMB2 is also turned on and working:


Thanks for the link! I'll go through all of those items in that page, see if something comes back incorrect!

Code:

Set-SmbClientConfiguration -RequireSecuritySignature $false

Yep! Just did it again though just to make sure, setting "A" for all. This is the issue I have when I try to open a shared drive on the network from this pc:



It sees a computer and my networked printer, but I cannot connect to that pc at all. The printer works just fine though! I can pin from cmd all the machines in the network just fine, but cannot see any shared drives in network. Crazy, right???

See if this works. Do this on all systems in network..

add "LanmanWorkstation" as an additional startup dependency for the "Function Discovery Resource Publication" (FDResPub) service, which seems to do the trick. To do this, you simply open an elevated command prompt (i.e. use the "run as administrator" right-click context menu option to start cmd.exe), then execute the following command:
sc config fdrespub depend= RpcSs/http/fdphost/LanmanWorkstation
Reboot each device after executing this command,

Make sure these services are set to automatic and running

DNS-Client – Server

Function Discovery Provider Host

Function Discovery Resource Publication

SSDP Discovery

UPNP Device Host

Windows Defender Firewall

I have had some weird network problems lately myself, and the one thing that always seems to work for me when nothing else works is to perform a Network reset in settings...



Give that a try and see if helps.

THAT WAS IT!!!!! You rock!!! Ran that command, checked that the other services were running (they were) and rebooted. Started back up, opened the surveillance machine and it showed me the video recording drive!!! I only had to run the command on one other machine, which was also a win11 box that I built last year, but it too worked perfectly after the command!

I sincerely thank you for your expertise in win11! You've saved me from going grey and losing my mind!!!

Just a note, you're using a "debloated" Windows. Typically background services are disabled for performance reasons, but they don't bother documenting which ones they chose to turn off. It comes with the territory.

Yes, this is absolutely true! The build is solid and works really well, but two big negatives is there's no contact info to get info from the builder and report bugs/issues, and second is what you said, there's no list of everything that's been done.

I understood the risks of using it, and made sure I could go back to my previous build without any major issues, I just didn't expect such a strange issue that isn't documented very well online. This one kicked my arse for sure!!! Glad I found this forum though, going through I've learned quite a few things already!

Without a community of people smarter than I, I'd be stuck with a standard build and all the garbage that comes with it! Thanks to y'all!
