Request for assistance with a SOHO network problem
« on: January 09, 2019, 07:39:19 AM »
This can be a suggested fix, or for someone to come to site and earn a couple of hundred bucks

Friend is a photographer, dealing with mainly school pictures. He operates from his home in Wynberg, Cape Town

There are 4 PCs

PC-2 is the main computer. The idea is to store the incoming pictures on PC-2 and two ladies who do editing, access the files over the network

PC-1 and PC-2 are connected to a ADSL router.
The ADSL router is connected to a switch in another room (actually an ADSL router with DHCP disabled)
Off the switch there are 2 more PCs, PC-3 and PC-4

From PC-2 I can ping all the others. They get their address from the ADSL router
On WIndows Explorer the other 3 PCs are shown on the Network tab

I cannot connect from PC-2 to PC-1, likewise I cannot connect from PC-3 and PC-4 to either PC-1 or PC-2
The error shown is "Windows cannot access" \\PC-1 cannot be found

PC-1 and PC-2 run Windows 10 Enterprise
PC-3 is Windows 7 Professional
PC-4 is WIndows 10 Enterprise
Network share is on
Drive and folders are shared for "Everybody" with full access
Network discovery is on
Workgroup is the same for all
The network does not have a Domain
Checked all the cables with a network cable tester, all 8 lights come on in correct order
All the PCs can access the Internet

The ADSL router is 192.168.1.1
DHCP on the second router is disabled

I note that Windows 10 no longer has a Homegroup facility

Have not fiddled with the Registry

Thank you

What IP is assigned to the Switch(Router)?
In the word : Scent, is it the S or the C that is silent?

Nothing.   Should there be?  I thought it was transparent

Okay, I skim read first time, my bad. You can ping all devices from each device? then routing is fine, sounds like a dodgy share option somewhere

Hello Chris

From what you explained, PC-1 and PC-2 connected to the ADSL router needs to be connected to the 2nd Router, acting as a switch, because they are probably not on the same network, as PC-3 and PC-4. This will result in the network shares not working.

What I would suggest you do:

1. Is to connect the ADSL Router 2 (acting as a switch) to ADSL Router 1, with one network cable and connect all the other PCs to ADSL 2/Switch. OR install a Switch connected to the ADSL Router 1 and connect all the PCs connected to this New switch. A 8 Port switch will be perfect. It does not have to be managed.

2. Make sure that all the PCs are on the same network - have the same IP Address Range. eg., from 192.168.1.2 to 192.168.1.254

3. On the ADSL Router 1 - reserve all the IP Addresses of the PCs and devices on the network via the DHCP settings on the Router. The reason for this is to not have different IP addresses every time the PCs or devices connects to the network. This will also help with the Network sharing.

4. Make sure that the Firewalls between the PCs are not enabled or allow file and print sharing through the firewall. Also check that the Anti-virus also does not block the sharing, via things like Intrusion Detection System (IDS) or HIPS settings.

Let me know if you need assistance.

Thanks to Craig, it was narrowed down to having to enable insecure guest logons on Lanman Workstation under Administrative Templates, Local Computer Policy

Prince, the items you enumerated above had already been done.  The second router has DHCP disabled.

Network discovery turned on, guest account enabled, firewall off, check the gpedit.msc as well for allowing certain accounts access to the computer over the network.
