Re: Cannot ping desktop from laptop or router

Tech-Archive recommends: Speed Up your PC by fixing your registry

Thanks Robert, but as I said, Norton has been uninstalled and the Windows
firewall has been disabled. Unfortunately, I had already reviewed the site
that you referenced and had no luck.

I'm thinking it's a TCP/IP, registry, or router issue at this point but I
just don't know hardware/networking/security that well so I don't know what
to check next.

I thought it was supposed to be easy to simply add a new computer to an
existing network.

I would check the firewall first. Or this search result may help.

IpconfigNo IP while the network cable is disconnected No operation can be
performed on the adapter One-way ping only Ping -a resolves to wrong
hostname ...

Hi all,

My problem looks similar to many others here, but I’m stumped. Any
suggestions would be much appreciated.

My setup:

• Cable modem
• Motorola VT2542 router
• Desktop computer, Windows XP Pro, version 2002, sp2
o Network name: ReadTheGreen
o IP Address: 192.168.15.2
o New self built
o XFX nForce 680i LT motherboard
o Core2 Quad Q6600 cpu
• Laptop Computer, Windows XP Home, version 2002, sp2
o Network name: BigTen
o IP Address: 192.168.15.2
o HP pavilion zd8000
• Workgroup Name: MSHOME on both machines


The Problem:
• The Desktop is a new machine that replaces an old Dell. I can’t get it
to
network properly with the laptop.
• The new desktop can successfully ping itself, the router and the laptop.
It can also view shared laptop files through Windows Explorer.
• The laptop can successfully ping itself and the router, but NOT the
desktop. I get the ‘Request timed out’ error.
• The laptop can ‘see’ the desktop in the MSHOME workgroup in Windows
Explorer, but when I try to access the desktop, I get the error:
‘’\\Readthegreen is not accessible. You might not have permission to use
this network resource. Contact the administrator of this server to find
out
if you have access permissions. The network path was not found.
• While logged into the router, http://192.168.15.1, there is a ‘ping test’
option under the Tools menu. Using that tool, I can ping the laptop
(192.168.15.3), but NOT the desktop (192.168.15.2).
• In summary, the desktop is not accessible by either the laptop or the
router

Attempted Solutions:
• Originally, both machines were running Norton Internet Security. I
added
the laptop’s IP address to the desktop’s list of trusted computers and
vice
versa using within Norton.
• When the above did not work, I disabled both the personal firewall and
intrusion prevention features of Norton on both machines. At the same
time,
I verified that the Windows firewall was not enabled.
• I verified that the registry values of both
\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Lsa\restrictanonymous and
\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Lsa\restrictanonymous
were
set to 0 (zero).
• I have enabled NetBIOS over TCP/IP on both machines (Network Connections
-> Local Area Connection -> Properties -> Internet Protocal (TCP/IP) ->
Properties -> Advanced -> WINS)
• I have now uninstalled Norton from the desktop and disabled the windows
firewall. I also reset the router to the factory defaults.
