SAMBA Server Issue

[Shrub Nuts]

Hey all,

 

First time ever making serious use of this forum, but I have hit a wall and typically would find another way to fix my problem but I am stumped and the internet is not helpful.

 

I have a Fios Router that I have branched a relatively simple network off of and have two File Servers that I keep on it. One for my folks and one for my own personal use.  Both run SAMBA and have various mounts setup as shares, but up until just yesterday my own personal one is no longer accessible from my personal Windows 10 machine. I have a tablet, a phone, and Windows 10 laptop that all are completely capable of connecting to Relay (the server's name) but my own desktop cannot now. They can ping each other and it seems like there is nothing seriously affecting the firewall that wouldn't allow SMB protocols to get through it.  The only big thing that has changed recently is that Lubuntu 19.04 reached end of life and I just bumped up to Lubuntu 19.10.  Windows machine hasn't had any remarkable updates or anything that I know of that would stop this either, but I just kind of want some rudimentary ideas on what else could possibly cause this cause this server is my bread and butter I use it for a lot and its a real shame it just up and stopped connecting.

 

Obviously more information will be needed just let me know what you need to know and I can elaborate.

Additional info now:

I factory reset my Windows 10 machine. Still no dice. Whatever is stopping me from seeing my SAMBA shares from specifically this desktop appears to be on the server side.

Again running Lubuntu 19.10 now and this Desktop is still the only machine that cannot connect to this server. I am adding in my smb.conf file now.

Is it completely inaccessible or just not visible on the network?

I've noticed Windows 10 is very unreliable at seeing Samba servers, I have to type the name of mine in manually now and then the shares show up.

It is completely invisible. I know my SAMBA protocol is working on my desktop because I have a similar SAMBA server that is running in the house that I can access just fine. It is only this one.  What I am starting to think is that there may be something that stopped the server from seeing my desktop? But there are no rules for it in the firewall and I have the firewall off even so I am not sure what is causing it.  I have tried so many things all with no results so I am thinking it might have had something to do with the upgrade process when I moved from 19.04 to 19.10 but I am not sure what would have happened that would stop it from seeing my desktop.

 

The real kicker is I can use RDP to login to my server totally fine as well.

Not even by direct IP. I can do it just by name.

So it seems to only not see my desktop in a way that would only matter for samba.
