can't ping Vista wireless lap top from LAN XP computers

G

Guest

My configuration for this problem started as two desktop computers running
Wndows XP Pro both connected to my private work group via an ethernet/DSL
switch. Then I purchased a lap top with a wireless addapter (802.11g) in it
running Vista Home Premium and swapped my Lan switch with a wireless/LAN/DSL
router.

I have it all working except: While I can ping the two XP computers from the
Vista computer and access the files on the XP computers from the Vista
computer, I can not do the reverse. A ping from either desktop to the lap top
always times out, and I can not get the lap top to appear in the "network
places" of the desktops.

What must I do to get access to the lap top with Vista from the desktops
with XP?

Sorry, Rick. No go. I already had network discovery enabled. Besides, the
Vista machine has no difficulties seeing files on the XP machines. It is the
other direction I am having troubles with.

OK. Lets take this one step at a time. With all I have done in implementing
the responses I have received the symptoms I see have changed.

First step, lets get the computers all talking together and lets get the
"ping" problems fixed first.

At this point I can:
1) From the Vista laptop - ping desk top (XP) "a" by name and IP.
2) From desktop "a" - ping lap top (Vista) by name and IP.
3) From desktop "b" (XP) - ping desktop "a" by IP but not by name
4) From desktop "b" - ping laptop by IP but not by name.

I can not:
1) From the lap top - ping desktop "b" by name or IP.
2) From desktop "a" - ping desktop "b" by name or IP.
3) From desktop "b" - ping desktop "a" by name (IP works).
4) From desktop "b" - png laptop by name (IP works).

Let's start with the basic question, what is wrong and on what machine and
how do I verify it. (I am NOT going to make any more changes until I can SEE
what the problem is! And I am only going to proceed one step at a time.)

Rick,
I do not find a "mode type" but I do find a "node type" so I assume that
is what you mean.

On "a" it is "mixed". On "b" it is "unknown". (For completeness, on the
laptop it is "hybrid".)

Hi,

Fat fingers there, it should be "node". Ok, do this on both machines: Run
regedit, navigate here:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters

Locate the Dhcpnodetype string and set it to 1 on both systems. The Vista
laptop is fine as hybrid.

Hi Rick,
On machine "a" it was a four (I set it to 1). On machine "b" the
parameter does not exist, so I added it to mirror the one on "a". Is there an
action needed to activate these new registry values? (I am guessing a reboot
of both desktops is needed.)

And is there a special meaning to the Dhcpnodetype registration parameter on
"b" not being there at all? When I installed the drivers for the router I was
expecting instructions to put something on the "b" machine, but the install
process was faulty and I had to get product support (for the router) to help
me. I gave them the complete configuration of the net, but they didn't
mention anything about putting anything on the "b" computer (and even though
I wondered about it, I didn't ask). If so I will call them again to get the
instructions. I have to also wonder about the Vista laptop, but I can imagine
it already had what ever support code is needed for this router.

BTW, before I got your last post, I had pings running from all machines to
all machines, and I was able to copy files from both desktops to the laptop
(but not from the laptop to the desktops). It turns out that I have two
firewalls on "b" and they were both on. One is the Windows Firewall and the
other was in Norton Internet Security.

I saw some posts about sharing files that I will investigate later, once I
am certain I have this "ping" problem fixed and stabilized.

Thanks,
Jack

Hi,

Yes, you need to reboot for the new entry to be active.

"b" was messed up because the entry was missing. Most times, you don't
actually need router software. Simply type the gateway address into IE's
address bar to access it. This can be seen in the same ipconfig command.
Normally, it's something like 192.168.0.1, just preface it with the normal
http:// prefix.

Thanks, Rick.
That got all of the ping problems resolved, at least for the moment. I
will be giving all I have done some time to "settle" just to make sure.

BTW, in order to ping from "b" to the laptop by name I had to reboot the
laptop. I guess the next test will be tomorrow after a night of powered off
machines. Then on to finding out about the file sharing procedures.

Rick, many thanks for your time and patience.
