Sorry I'm just busy at the moment working so I'm writing this quickly into a text file. Please read my entire post as it is read and that's what I'm supporting you with. Any further discussion depends on what's going on with your problem and like I said it's very
complicated could be one of dozens of problems...
This is what I want you to look at:
UPnP Device Host
SDDP Discovery
Peer Name Resolution Protocol
Peer Networking Grouping
Peer Networking Identity Manager
PNRP Machine Name Publication Service
Function Discovery Provider Host
Function Discovery Resource Publication
They all need to be running within Windows otherwise file sharing won't work. If you go into Services and make sure they're all running by default when Win10/Win11 boots and make sure that they are all automatic set. If for some reason one or more of them don't work you've got something wrong with your network config files.
Not forgetting of course that Microsoft like to turn all this stuff off on the regular which is why I do all my telemetry blocking so you don't have to keep going back again and again to switch them all back on. You should also check that Peer 2 Peer Networking is enabled in Group Policy otherwise it won't run for the same reasons as the 8 Services I listed.
Sorry I can't help much more now as I've got work to do so I'm just trying to be quick. There's all kinds of problems that can cause this and I've found lately that Router issues like bad firmware also can cause problems I had a firmware that was released back in the summer of 2022 and the Japanese programmers over there made a complete mess of it so it didn't function right which was a really big downer for me luckily I managed to revert back to an older firmware. There seems to be stacks of programmer errors these days in everything which just confuses the hell out of what everybody is doing and I just hate it.
Just make sure your Workgroup is the same for both machines and then get back to me later and see how things are going. Windows really isn't as
complicated as what people think and I'm sorry but I've been dealing with all this for years now otherwise I couldn't be an uploader on here and I wouldn't be able to move movie files around which is crucial to my setup so I have to make it all work or just go bust which the second option is not an option for me.

I like that thread, they are touching on the right kind of thing. Not sure if it works, maybe if you have a look at this thread Robert and see what happens.
From the code that you mentioned, notice how the very first thing mentioned was that the services aren't running like what I said..
I just hope that it's something simple but if you want to go deeper into the problem and can't solve it I'll try my best to help.
