Another Vista/XP networking headache/mystery...help?

By TracyF ·
Put on your thinking caps everyone...

Here's the scenario: Vista Ult. desktop (PC1), Vista Ult. desktop (PC2), Vista Prem. laptop, XP Pro laptop. Home network (Netgear ADSL modem/router). Set as "private" as far as Vista goes. Laptops are wireless, desktops are wired.

Ok, here's who sees who:

XP laptop sees/accesses all but PC1.
PC2 "" "" ""
Vista laptop "" ""

PC1 cannot see XP laptop- but sees/accesses all else...This is the problem child of the group.

Have been through all the permissions/settings to verify that PC2, PC1, Vista laptop are exactly the same (they are).

No passwords, no firewalls, same group, etc...Same everything...We're banging our heads against the wall, trying to locate an answer.

This is the error:

"PC1 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. Access is denied."

As everything is the same on the 3 Vista machines, we just can't imagine what else there is to change/edit? Been Googling non-stop and nothing found has been the answer (so far). It's a small consolation that so many people have issues w/Vista & networking- but at least we're not alone...just need a solution.

Ideas so very appreciated,

Tracy

I know the answer !! ...now what is it called?

by OldER Mycroft In reply to Another Vista/XP networki ...

I just can't remember the name of it !! ...

The XP laptop needs to have something downloaded to it, installed, then turned ON.

THAT is why none of the Vista systems can 'see' it.

Bear with me - it'll come back to me - it usually does!

Got it !! I think this might solve your problem ...

Check this out:

According to M$ ::

Overview
This package contains the Link Layer Topology Discovery (LLTD) responder. The network map on a computer running Windows Vista shows a graphical view of the computers and devices on your network and how they are connected by using the LLTD protocol. The LLTD responder must be installed on a computer running Windows XP before it can be detected and appear on the network map. After you install this item, you may have to restart your computer.


Actually I've just re-read the OP and I might have it ar$e over t!t.

Oops.

Hey, O.M.- not quite what I need...

by TracyF In reply to Another Vista/XP networki ...

...it's not the XP lappy we're all that concerned over- it's PC1, running Vista, that simply refuses to allow access.

Funnily enough, RE: that LLTD download- I've never had to install it yet? Haven't had any issues w/it (so far, knock-on-wood).

No, it's just the one, Vista machine that no one can get to- & it's driving us bonkers! We've both done a decent amount of PC troubleshooting & we're truly baffled...

Anyone else recognize these symptoms?

Thanks,

Tracy

Long shots!

by cale In reply to Another Vista/XP networki ...

Assuming that every computer can ping every computer, and that all the network settings are correct (firewalls all off, etc), I would dive into the Local Security Policy of PC1. I am thinking in peticular of the authentication schemes used (similar to the old "Classic - Users authenticate as themselves" setting?). Also, what versions of vista are each running?

Cuddos to OM for LLTD!

Still no access...sigh...

by TracyF In reply to This is

I've been working on this, off and on, since first making this post- and I'm no further ahead. I swear I've tried everything I could find via Google/tech groups. I just cannot believe that I'm the only person stuck like this (& surprised that no TR guru has the answer)?

Again, there's no prob in accessing XP from Vista- it's the other way 'round (& only this one Vista PC that won't allow access- 2 other will?). Also, I can print to a USB printer that's connected to this problem Vista machine?

Just doing a "bump" to see if anyone else has solved this mystery?

Thanks all,

Tracy

A couple of things

by Jacky Howe In reply to Still no access...sigh...

to check that you may or may not have looked at. Vista can be a pain sometimes.

Turn on network discovery in Network and Sharing Center

There are two network discovery states:

On

This state enables you to see other network computers and devices from your computer and enables people on other network computers to see your computer. You can also access shared files and devices on other computers and other people can access shared files devices on your computer.

Off

This state prevents you from seeing other network computers and devices from your computer and prevents people on other network computers from seeing your computer. You cannot access shared files and devices on other computers and other people cannot access shared files and devices on your computer.
