A-110 suddenly can't see PC

[Larkspeed]

We have one machine in our house that parses RSS feeds and then downloads the TV shows we want to watch.

My wife can then access these shows via network from the A-110 we have in the Bedroom.

This has worked flawlessly for over a year then all of a sudden yesterday the PCH could not see the server PC anymore.

It can see other machines on the network it's only the server it cannot see.

I will add that all other machines on the network can see and stream from the server machine fine. So can the AC Ryan we have in the living room.

So the fault clearly lies with the PCH.

the workgroup name in this house is the default workgroup so it's easy when a new machine is added.

I tried changing the workgroup name of the server machine then then restarted the PCH. It then saw the new workgroup that the server was on but failed to see the other one.

I played a file from the server perfectly fine but as soon as I dropped back to the network browser screen the new workgroup had disappeared and the old one was now visible again and the server machine was gone again.

Changing the server machine back to the original workgroup name had no effect.

Entire network has been restarted and everything is on cabled connections not wireless. All cables have been checked with a LAN cable tester and they are all fine.
