PC Can't See Others on network, but can ping them by IP.

[efritsch]

I have 3 PC's on my network.

Two running XP Pro and a Laptop running Vista. One XP Machine and the
Laptop are wireless to the router. The Other XP Machine is wired to the
router. All 3 Machines can access the internet with no issues.

The Vista Machine and the wired XP machine can communicate just fine. They
can see the Wireless XP Machine but can't access it. "Windows Cannot Access
\\Machine 3"

The Wireless Machine can see the router but not the other two PC's. It can
ping them via IP Address, but not by name.

I have been beating my head against the keyboard, the monitor, the wall...
and can't get the damn thing to play nice and talk to the other PC's.

1. Make sure all computer have been enabled NetBIOS over TCP/IP.
2. Make sure you have assigned permissions in Security tab.

I have enables NetBIOS over TCP/IP on all machines. Only one machine has a
problem. I do have shared folders on the problem machine and the firewall
disabled.

Check in your anti-virus software. Some anti-virus software have an
Internet Worm protection module which will block the NetBIOS name
resolution.
