Windows 10: PC is not reachable from local network but still has internet access

I have 3 win 11 PCs and they all are connected on my local network. This HP PC normally works fine but about every 3 days it is not reachable through my network, The PC does not lose internet access but my other PC cannot reach the this PC Ping does not work. The other PC do not have this problem and they all have the same OS. I fix the problem by rebooting the PC and it again it is reachable for about the next 3 days.The PC with the problem is HP ENVY 15t Quad TouchSmart Any suggestions on a fix.

Connecting computer with no internet connection to network printer


@dk1971

1. Open Admin command and type: ipconfig
   
   
   
2. Win+X->Control Panel->Netwok and Sharing Center
   Follow the screen shot. This should disable internet access from this PC but allows access to local device(s)
   NOTE: Use the IP & Subnet Mask from step 1. Leave Default gateway & DNS Server blank
   
   
   

 

Internet only, No Local network

Hello,

I have windows 10 and I have my own router that I use for internet access and local networking with other pc's also running windows 10 with shared drives and printers. It has worked flawlessly locally connecting to other pc/drives and printer sharing.

My network by clock has always said network and internet access until today.... Now it just says internet access and my local network does not work.

So why all of a sudden do I only have internet with NO LOCAL network access ???? All other pc's on my home network still function and connect to local just fine.

Rebooting router does nothing...

rebooting this pc does nothing...

resetting network on this pc does nothing....

All share settings are correct and network and sharing shows "private network" as it should.

 

So today our office network connections just vanished..first internet, then all local

We have 3 networked pc's:

My personal work pc, let's call it pc A (Win 7 x86) which is the 'server' containing the software for running our company is wired to an external modem and to a router/switch. From the router/switch there's a wired connection to Pc B (Win 7 x86), and another wired connection to Pc C (XP x86) which is attached to the printer.

Till 11:00AM everything was fine. Suddenly there was no internet connection on all 3 pc's. But the local network was still functioning fine, pc's B and C could access the software in pc A and all 3 computers could access the printer. So I didn't bother much until my dad needed internet to check work correspondence.

So we rebooted all 3 pc's.

After doing so, pc C became invisible, obviously together with its printer... We couldn't access it to print, and it couldn't access the company software on pc A.

I tried a system restore on pc C but kept getting the message that it was unsuccessful, no matter which dates I tried.

So we rebooted everything again - and went from bad to worse because now even pc B got thrown out of the network.

I checked the network settings on pc A. Something was surely wrong - the network was called "Unidentified Network" whereas before I'm sure it was called "Work....something" or "Home...something" *Oh Well hwell:

I tried a system restore on pc A, only to get the same message that the system restore was unsuccessful no matter which dates I tried *Confused

I can temporarily get stuff running for tomorrow's work (I'll unplug the printer from pc C and plug it into pc A and we'll use only one computer instead of 3...) but it's an inconvenient short term solution *Oh Well hwell:


What could have caused this i.e. first the external internet connection got lost and then all local connections got lost as well?

Networking is a very cloudy area for me (I'm a n00b).. where do you suggest I start working to fix this?
