Cannot connect or ping this Vista client!

Specs: Microsoft Windows Vista Home Premium, 1.733 GHz / 2037 MB
What would prevent a Windows Vista client from preventing a ping to it's IP address or hostname? I have a laptop running Vista Home Premium that's acting like it's "filtered." It connects to my wireless network and gets internet. It shows up in the routers DHCP clieet table with it's name and it's assigned IP address- but I cannot connect to it's shares nor even ping it from my desktop PC. I can ping and connect from my laptop to my Desktop with no problems. I can map it from the desktop> seeing the laptop on the network map with it's name and address... From the desktop, pinging or connecting to it- times out or gets unknown host.

My desktop is multi-boot: Win7, Windows Vista, Ubuntu 10.04.1 Desktop, OpenSolaris 2010.03 snv_134, Solaris 10, others... I can connect from my laptop to my Desktop- if I'm booted up in a Windows OS on the Desktop PC, but only as a network shared folder... Not as a windows share. ...and only "one-way."

I guess I "could" boot up the Laptop on a Linux or Unix LiveCD and see if I ping it from my desktop PC. I've already done this from an Ubuntu 9.10 LiveCD and everything seemed fine with filshares between them both ways- leading my to suspect the Laptop's "Vista" settings and services.

Confirmed... Can boot up this Laptop with Ubuntu 10.10 Desktop Edition LiveCD and I CAN ping to it from my desktop.

So, what network or hardware driver setting or service in "Vista Home Premium" is affecting this laptop? Ideas anyone?

Ok(seawatch1?)... That articlewas basic Windows networking- migrating an XP to Vista into a home network. I guess I should explain what I've checked on the laptop.

Network is set up as autoconnect wireless, Network Discovery on, Filesharing on, Printsharing and Media sharing also on. Workgroup is WORKGROUP. All the Network settings are the same as the other PC's... as far as I can tell.

The NIC driver is Atheros Wireless driver (current.) It is as DHCP client, associated to the shares.

Filesharing permissions and security settings, user permissions and rights, group permissions and rights... and so on are set as the others. Seems to be running the same protocols and transport layers as the other clients. SMB and CIFS is same. Group membership is right. The registry keys for thse are correct and valid. The access control list (ACL) in the registry seems correct and valid. The seurity policies set in the registry seem correct.

I've checked the system monitor logs and I don't see anthing abnormal going on. I turned on incoming and outgoing logging in my router. Nothing jumps out at me from those logs either.

I went through the local services, reconciling them with my desktop to see that they had the same services running. NTLM acknowledement (lmcompatibilitylevel) is setup the same as the others in the registry.... and other revolent registry setting seem the same...

It has the standard services running- Client for Microsoft Networks, VirtualBox bridged networking driver, Virtual machine networking sevices, Qos Packet Scheduler, File and Pint Sharing for Microsoft Networks, Internet Protocol Version 6(TCP/IPv6), Inernet Protocol Version4(TCP/IPv4), Link-Layer Topology Discovery MApper I/O driver, Link-Layer Topology Discovery Responder...

I turned off the window's and Norton firewalls on this computer and the windows firewall on the desktop. No change.

The general services, such as sysmonlog, SammSS, ntmSs, netddedsdm, netdde, dmserver, clipsrv and Browser... ok.

One service that is runnng that is "not". on th others is a "World Wide Web Publishing Service" in local extended services.... Anyone know about what might happen if I disable this service?

I guess I could turn on WinDebug on both machines and "see" what each is passing and receiving. I've already gone through a mountiain of data in the last few days. As you might guess, "that" would generate a novel worth of data to sort through!
