PCs cant see each other/Names missing on router

June 19, 2017 at 15:44:47
Specs: Windows 10, 16GB
All 3 of my PCs are running the latest version of Windows 10. They all have; Network discovery turned on, file and printer sharing turned on, Password protected sharing is turned off and they are all Wired to the router. Router is a WRT310N V2 running DD-WRT v24-sp2 std-nokaid-small. They were all set up with static IPs because each uses apps that require port forwarding.

After over a year, Out of no where, each PC intermittently would not be able to see the other PCs on the network. Though, the other PCs could see that computer. It started happening more often and I looked around and someone suggested to turn off the login PIN and use just the password login. That seem to fix it but only shortly, now it is even worse.

Now, none of my computers will see each other at all. the computers can see the printer, Xbox One and both my Rokus but not the other computers. As stated in the title I noticed when I go into the router that the computers are shown connected under LAN but their names are blank. Besides them not seeing each other; they have full internet access, ports forwarded to them are open and apps work with no issues...

I cant figure it out, please if you have any ideas..

Better try this simple approach first if you haven't already. Just power the router off for about half a minutes. Not too hopeful but it has cured some obscure faults at times.

Always pop back and let us know the outcome - thanks

Not a bad idea to restart all of the computers at the same time as router restart for a complete fresh start.

I have shut the entire neighborhood down multiple times following the day old Rez cycle.. Shut every device down, Boot Modem wait mins, Boot router and wait mins, boot each Wired device one at a time and then boot any Wi-Fi devices. I also tried switching my Wired Static PCs back to Auto/Dynamic and no go.

To note: I restart my PCs daily, restart my router weekly and restart my modem biweekly.

I even gave the router a 100 IP address grace window so no IP fights...

Have you ever updated the firmware on your router? If not, make sure it has the most recent firmware on it. If it does require updating, does the update fix the issue?

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

I suspect we're too focused on the router, which is odd 'cause I don't see evidence to indicate it's at fault.

Q1: Can the computers ping each other by IP?
Q2: Can you access shares by IP?
Q3: Have you disabled the firewall on these machines?
Q4: If you have answered yes to the previous questions, have you considered just putting the machines into everyone's hosts files, so you don't have to worry about name discovery?
Q5: Have you tried rebuilding the homegroup?
Q6: Does the command nbtstat -R help?

Ok, today I set all of the computers to Auto/Dynamic and restarted everything. Desktop1 can see Desktop3 only, Desktop2 can see Desktop3 only and Desktop3 can see ALL 3 of them.... I have to Firewall completely disabled on all 3 computers. All 3 computers successfully Ping each other with no packet loss.

When I go into CMD and type "net view" on Desktop1 and Desktop2 I get the following message, "The service has not been started. More help is available by typing NET HELPPMSG 2184". On Desktop3 I get a list of all the computers on the network.

Press the Windows key + R to get the run dialog box, and type "services.msc". That should bring up the services list. Make sure Computer Browser is running. Make sure the Homegroup services are running. Make sure Server and Workstation services are running.

All the above services were running except for Home Group Listener. Home Group Listener is also not running on the computer that can see the other computers. I still don't know what the issue is. This has to be some issue on boot because now Desktop3/Desktop1 cant see each other or Desktop2 but Desktop2 can see all 3 computers now.

Typing "net view" on Desktop3/Desktop1 gives me "The service has not been started. More help is available by typing NET HELPPMSG 2184". All computers can ping each other with no packet loss. Typing "net view" on Desktop2 gives me a complete list of the network devices.

It may be a Windows update that is the cause, look at this Google search and similar:

@Sluc
I am very Tech savvy and I do everything I know and everything I can possibly find before using Computing.net as a go to brainstorm... While the suggestion was helpful, thank you, I did already exhaust all those videos before coming here. All my services that should be running are running.

@Fingers
This very well may be true. I get ridiculous DC's from online gaming off and on. When I get DC'd, I run a speed test which comes back with no issues...

Did you see this one:

While not the same, appears to be related to your experience. You may be able to uninstall an update or two that was installed just prior to the date your original problem began and see if that one fixes the problem. You can also look into any optional updates to see if there is any fixes for this listed there that you can install.
