Please help me resolve this home network issue

I’ve spent weeks trying to solve this and it’s driving me insane. Please help if you can.
I have a home network with 4 machines, all running Windows10. All installations are about 2 months old, and the problem only started after the recent Windows reinstall.
The main desktop PC (PC1) shows up in all the other network lists, but if I attempt to connect, it eventually times out, stating that: ‘Windows cannot access \\PC1’ (error code 0x80070035). If I ask Windows to diagnose, it states: ‘Your computer appears to be correctly configured, but PC1 (server) is not responding’.
The server (PC1) can access all other Public Folders without issue, and they can all access each other. None however, can access PC1 L I’ve checked and triple checked, but all network settings are the same on all machines. And yet, none of the client machines can access my main desktop PC. So basically, it works one way, but not the other:-(
I’ll endeavour to supply as much info here as possible.

The tech spec and details are:
PC1 and PC2 are hard wired with RJ45 via BT Hub
Remainder are wireless laptops
Active network shown as Private on all four
Comp names: PC1, PC2, PC3, PC4.
Workgroup: MBNET (all the same)

All PCs are set to:
Turn on network discovery
Turn on automatic setup of network connected devices
Turn on file and printer sharing
Allow Windows to manage homegroup connections
Turn off password protected sharing
Removed all Antivirus software and turned OFF Windows Defender Firewall on all machines.

None of my Windows ‘Restore Points’ or backups change it.
All PCs access the internet without issue.

If I ‘ping’ PC1 as 192.168.1.101’ from clients, then:

If I try to ping using its name ‘PC1’ I get:

This is SO frustrating

I’ve Googled ‘error code 0x80070035’ and tried many varied different fixes, all to with zero results.

Cannot Connect to Remote Systems Using Host Name

Wow lots to check on there. Thank you very much will report back tmrw

You are very welcome!

What was your anti virusa lot if you remove it it block the net and you need to use their tool from their website to remove whats left avast is one of the ones that does this.
OPen a admin cmd prompt type each cmd press return after every one
netsh advfirewall reset
netsh advfirewall set allprofiles state ON
ipconfig /flushdns
netsh winsock reset catalog
netsh int ip reset c:\resetlog.txt
ipconfig /release
ipconfig /renew
netsh int ipv4 reset
netsh int ipv6 reset
bitsadmin /reset /allusers


then reboot

As these are fresh install's, there has not yet been any AV software installed. Only Defender, which is disabled while I try to sort this. Not back on my network now until tmrw, so will try all suggestions and report back then.
Extremely grateful for the feedback.

Struggling with this. I think this info relates to an earlier version of Windows. Its all a little beyond me:-( None of the machines appear to have any entries for DNS

Tried all this but it hasn't changed anything:-(

It makes no sense to me as all settings appear exactly the same on all machines:-(
I've got files and folders I really need to share across my network:-(

On PC1>go to settings>Network and Internet> at the bottom of the page> click on network Reset. It takes 5 min. It will come up with a box that says do you want this PC to be Discovered. Check yes. That fixed mine.
