Hi,

When my Netgear DG814 died last week, I replaced it with a DG834. I got
it set up and it connects to the Internet just fine. However, I can no
longer see any of the other 3 PC's in the Workgroup. This means I
cannot share the printer nor acccess the shared folder we have.

I spoke to Netgear Support who said "No problem, just go into the
router settings and tick the box for "Disable Port Scan and DOS
Protection".

This doesn't seem right to me as doesn't this switch off the firewall
completely.

Is there a way round this without killing the firewall?

What are you running (Windows XP?) on the PCs? I don't know the DG814 but
my DG384G assigns IP addresses using DCHP (they're all in the range
192.168.0.XXX). I needed to configure the firewalls on my PCs to realise
that any PC with an IP address in this range was "a friend" and that access
was allowed.

You can be more precise by doing the following...

1. Look at the DG384G config to discover which MAC addresses your PCs have.
2. Use the "reserve addresses" feature to ensure that each MAC address (PC)
is always assigned the same IP address.
3. Enable each firewall to only let through the IP addresses reserved for
the other machines.

Might be overkill but some feel its worth doing this.

BTW, if this is a DG384G, make sure you have MAC filtering, WPA-PSK, hide
SSID, changed SSID from the default etc. configured on the wireless side.
Don't want any unexpected "guests" do you ;-).

Do you have the same software firewall on all three computers? try disabling
it just to see if that is the problem, ie your old address series
192.168.x.x was maybe 1.x and now it is 0.x

I can ping the DG834 and any of the PC's from each of the PC's. The IP
addresses of the PC's are 192.168.0.2 , 192.168.0.3 and 192.168.0.4.

go to run and type
\\192.168.0.2 (from any of the PCs that arent 0.2) and see if you can access
the shared folders on them, try it on the other pcs.

Did that, and still can't see the shared folders. Whilst I can Ping any
PC, none of the PC's can see any other PC in Network Neighborhood so
there's no way I'd be able to see the folders.
I've done ipconnfig /release and ipconfig /renew on each PC and that
goes OK. Also I get internet access from any PC. So surely it's got to
be something about the DG834's default settings.as I had full sharing
across the workgroup on the DG814 on its default settings.
Stumped I am.

I'm running XP on 2 PC's and W2K on the other.

The DG814 is an early predecessor to the DG834 ie a wired (only)
Modem/router with DHCP/NAT/Firewall - same as your DG834G but no
wireless capability.

I don't have any firewalls running on the PC's.

Would seem rather odd for that to be the problem (because as far as I know,
the kit I've got here has a 4-port hub/switch with a single connection to
the router portion (and thence the ADSL modem connection) so "rules" for
what to pass/drop are carried out between the one connection off this
nominal "hub" and the router, not on each of the 4 ports (which is how
your setup is behaving, apparently).

Really quite puzzling why this is no longer operating. If you have access
to some 5+ port hub/switch that you could use to connect the PCs on, with
one connection from that unit back to the DG834G (or let the PCs learn IP
addresses, then plug them into the hub/switch) you can see if the DG834
is causing it to stop working, or something PC-side... I've a half dozen
hubs and switches, with anything up to 24 ports, which I'd happily lend,
but have no idea where you are... Anyway, these days 5 and 8 port units
come pretty cheap (though I understand any reluctance to buy when you'd
normally not need to do so). Good luck.

Many thanks for the offer but I can borrow a small hub from work next
Monday so I might give that a try.

Hmm. I'm a bit stumped by this one too. My immediate thought was software
firewalls such as Norton, but you're not using one. And all the PCs can ping
each other as well as pinging the router?

From a DOS prompt (which you'd use for ipconfig or ping) on one of the PCs,
try the following commands and see if any of them work. I'm assuming the the
PC that you're running the commands on is called PC1 and the other two PCs
are called PC2 and PC3 (as shown by the hostname command at the DOS prompt).

- ping PC1
- ping PC2 (should successfully resolve the name to an IP, then ping
that IP)
- net view (should display hostnames of all PCs in workgroup)
- net view \\PC1 (should display PC1's shares on PC1)
- net view \\PC2 (should display PC2's shares on PC1)
- net view \\192.168.0.2 (PC1's IP)
- net view \\192.168.0.3 (PC2's IP)

If these comands fail, the error number may give a clue to the problem. The
normal failure of "net view \\pc1" is error 53 "path not found", indicating
that the PC cannot locate the remote computer by network name.

Open the router's config page by browsing to 192.168.0.1. (By the way, I
suggest you add a line "192.168.0.1 router" to
\windows\system32\drivers\etc\hosts (with a tab character before "router")
so you can browse to a "URL" of "router", to save you having to type in the
router's IP each time.)

I presume the DG834 is very similar to the DG834G and DG834GT (54 and 108
Mbps wireless versions of the DG834 non-wireless router) and will have
similar menus.

Look on the Maintenance -> Attached Devices menu: you should see the IP
addresses of all attached PCs. The Device Name column should show the each
PC's hostname; if it says Unknown, that suggests that PCs are not
broadcasting their names.

It may help to enable TCP NetBIOS on each of the PCs, as NetBIOS is one of
the mechanisms by which PCs broadcast their names so they can access each
others' shares. To do this:

- Control Panel | Network Connections | (right click on Local Area Network
icon) | Properties
- Highlight TCP/IP in " This connection uses"
- on the General tabsheet, press Advanced and then switch to the WINS
tabsheet
- In "NetBIOS setting" change from Default to Enable NetBIOS; press OK as
required


Back in DOS prompt, try "nbtstat -n" which should give a list like

NetBIOS Local Name Table

Name Type Status
---------------------------------------------
MARTINLAPTOP <00> UNIQUE Registered
MARTINLAPTOP <20> UNIQUE Registered
MUND <00> GROUP Registered
MUND <1E> GROUP Registered
MUND <1D> UNIQUE Registered
..__MSBROWSE__.<01> GROUP Registered

where, in my case, MARTINLAPTOP is this PC's hostname and MUND is the
workgroup.

Similarly, "nbtstat -a PC2" should display a corresponding list from PC2 and
"nbtstat -c" should display something like

Name Type Host Address Life [sec]
------------------------------------------------------------
MARTINU <20> UNIQUE 192.168.0.6 595
MARTINU <00> UNIQUE 192.168.0.6 595
MARTIN-MESH <20> UNIQUE 192.168.0.2 525
MARTIN-MESH <00> UNIQUE 192.168.0.2 422

where MARTINU and MARTIN-MESH are the other two PCs on my network.

So far as I can see all the other posts replying to this question have
talked about changing things (firewalls) on the PCs. But your PCs worked
before, and all you have changed is the router.

The router might have a different LAN address to the previous one - so
reboot all the PCs to ensure that the acquire their address correctly from
the router. But yo probably have done this anyway.

Netgear Support clearly think there is something in their router which is
causing this problem. I'm not familiar with theDG834 but it is possible
that the router applies some filtering between ports on the LAN and you
should follow the advice given.

The router will continue to provide the functions of a firewall in that it
provides NAT (Network Address Translation). This hides the PCs on your LAN
from the internet, ensuring that the only traffic allowed in is that which
is in reply to outgoing requests. Given that you are not publishing a
website via this router that is all the firewall you need.

Let us know what happens when you have tried this.

XP and W2K have a habit of not very often refreshing the browse info

Also if they're all workstations, they'll have the same browse level,
and will be fighting auctions all the time to be the browse master for
the workgroup. You could probably reconfigure one of your
workstations to be browse master. This /might/ help. Also you do
sometimes need to leave all the PCs on for a fairly long time, maybe
hours, unless you have a domain controller around somewhere.

I 'fixed' this by putting Samba on a Linux box and giving it a higher
level, so it always wins elections. :-)

How did you set Samba to a "higher level"?

I had a similar problem recently, have you entered the XP machine's log on

In fact it wouldn't hurt to do the same on the XP machines, entering the 2k
user name.

However if it worked with your old set up without the need for that, it's
odd it's not doing it now.

I doubt it - in Yvonne's case all was OK when using a Netgear DG814

Given that things were OK, no firewalls involved, and no change to
the PCs, the possible problems over user accounts on Win 2000 vs
Win XP seems extremely different to me...

Refreshing he browse list can take several minutes, but:

If you "search" for a workstation by name, you should find it within
seconds.

If you browse to the IP address of the workstation, you should see the
available shared files.

From what you say, neither of these work; yet you can ping the workstations.
This normally mans that traffic is being blocked by a firewall. You say
there's no firewalls. Netgear Support imply that something in their router
blocks traffic between the LAN ports. Have you tried the correction that
they suggested?

Agree with all below, but perhaps also check the router's DNS settings ...

The default DHCP setting provided by the router should configure the PCs to
point to the router itself as the DNS server. Requests for unknown names
will then be passed to the outside world - and will of course fail if the
request is for an internal PC name. The PCs will then use netBIOS name
resolution to identify each other, and each will build a table of the other
computers it knows about. This is controlled by the value in the node type.
As explained elsewhere, the process will take time.

Misconfigured DNS might slow this down even more - but I don't see how it
will cause it to fail unless all your computer names are the same as
computers somewhere on the internet!

The command "nbtstat -r" will report what each machine kniows about the
other machines on the LAN.

Martin,

Thanks for the guidance. Sorry for the deay in responding but work got
in the way.I'll bring you up to date.

I've re-done the WORKGROUP and all the shares and can now get the two
machines running XP to see each other and access all the shares. The
one PC that runs W2K cannot see the two XP machines but these two XP
machines can access a shared folder on the W2K machine.

I've enabled NetBios over TCP/IP on all but this makes no diffetrence.

I did the nbtstat -n on each but before giving you the results I would
advise that the machines are as follows:-

LAPTOP - running XP with an IP of 192.168.0.4
LOUNGE - running XP with an IP of 192.168.0.2
STUDY - running W2K with an IP of 192.168.0.3

The Netgear router is 192.168.0.1

Running NBTSTAT -n on LAPTOP gives:-

LAPTOP <00> UNIQUE REGISTERED
WORKGROUP <00> GROUP REGISTERED
LAPTOP <20> UNIQUE REGISTERED
WORKGROUP <1E> GROUP REGISTERED
WORKGROUP <1D> GROUP REGISTERED
..____MSBROWSE_____.<01> GROUP

WIRELESS CONNECTION
Node IPADDRESS: [0.0.0.0] Scope ID:[ ]
No Names in Cache



Running NBTSTAT -n on LOUNGE gives:-

LOUNGE <00> UNIQUE REGISTERED
WORKGROUP <00> GROUP REGISTERED
LOUNGE <20> UNIQUE REGISTERED
WORKGROUP <1E> GROUP REGISTERED



Running NBTSTAT -n on STUDY gives:-

STUDY <20> UNIQUE REGISTERED
STUDY <03> UNIQUE REGISTERED
ADMINISTRATOR <03> GROUP REGISTERED

Running NBTSTAT -a LOUNGE from STUDY gives same info as before plus the
MAC address.
Running NBTSTAT -a LAPTOP from STUDY gives same info as before plus the
MAC address.
Running NBTSTAT -A gives the same info on other machines.

Running NET VIEW from STUDY to the others with the IP addresses shows
all the shares OK.
BUT Running NET VIEW from STUDY with \\LOUNGE or\\LAPTOP gives: -

"SYSTEM ERROR 53 has occurred.
The Network path not found"


I then added "192.168.0.1 router" to the Hosts file on STUDY but
that made no difference.
