Back into the fray. I am sharing Stan's frustration with MS. I have tried all the suggestions (and others in this thread) to no avail. I also tried switching FDResPub off and on again as you have suggested. No change. My local 24H2 machine (with W11 reinstalled) does not show itself or any other network device under Networks (Computer. (Except for a Synology NAS). But this machine and its shares are visible to all other 23H2 machines on the network which are working fine. Also, I can access other machines on the network from the problem 24H2 machine using network shares and mapping. So, the issue does not appear to be a restriction to access, but a problem with display in Explorer. Clearly, there is something(s) that needs to be changed having upgraded to 24H2. But I cannot find out what it is. Grateful to you for your efforts though. What I need to know from someone who has experienced this issue is what changes they made which solved the problem.
Why does not MS recognise this issue and resolve it?
