XP computer doesn't see Vista computer on network

I have a home wireless network, a "standard" one: the router is attached to
a desktop (XP) and I have a laptop (Vista) that is wireless. I print using
printer sharing on the desktop, so I know the laptop "sees" the desktop, at
least for that (or is it that the laptop sees the desktop?). That's
confirmed in Network -- on the laptop, I see the deskrop's Documents
,Shared Documents and Printers. However, it doesn't work in the other
direction: nothing on the laptop, not even the laptop itself, shows up.
However, if I click on "view workgroup computers" in Start...My Network
Places on the desktop, the laptop computer is listed. However, if I
double-click on that icon, I get only the Printers and Public folders.

I've already installed the Link Layer Topology Discovery (LLTD) Responder,
or at least I thought I did. I went through the MS KB document (KB922120),
but when I ran services.msc on the desktop, it wasn't running. Besides, I'm
not sure that service does what I want.

I've enabled file sharing, to allow all computers on the network to write to
the Shared Documents folder. However, when I try to save a document there
(from my laptop), it won't let me.

Any suggestions?

 

It could be a 3rd party security software issue. Can you ping the laptop by
IP?

Hi
Make sure that the Sharing is configured correctly and use disk/directory
mapping.

Successful Sharing involves some general consideration in Network settings,

As well as specific adjustment of each computer according to what it is
allowed to be shared.

How do I do that? I ran Start...run IPCONFIG, but I only got a DOS windows
that flashed much to fast for me to read.

 

Start, Run, CMD. Then run IPCONFIG in the resultant window.

 

Yes, I can.

 

Check all / any anti-virus or firewall software. Some place limits
on the "NetBIOS name resolution" (blocks it completely) because this
is a method that most Internet worm style virus can exploit. So you
can not find the PC by name (ie: \\VistaPC) but you may be able to
find it by IP (ie: \\192.168.0.1.)
