Vista box not resolving IP from hostname

Good Evening,

I have a minor issue with one of my home computers! I have numerous
systems connected to my home network (wired and wireless). They
either run XP or Vista and linked by a router.

One of my boxes cannot resolve local LAN IP's by the computer
hostname. If I ping barney I get "ping request could not find host
barney..." where it should return 192.168.0.2. All other computers on
my network can ping this and all local systems. The system I am
having issues with is Vista.

All systems are configured as follows:

- DHCP I did confirm it is getting a local address
- Firewall is turned off
- Confirmed no malware is on the system having issues
- Confirmed other PC's on the LAN can ping the bad box.
- Confirmed all network settings are the same on all vista boxes
(Network Discovery Settings, Sharing, etc).
- Confirmed system having issue (a laptop) has the issue both wired
and wireless.
- Confirmed all services that I know of are in their proper states.

Any help appreciated.
 
So in essence your machine is not performing DNS lookups correctly...

The only other time I have seen this problem is when I had 2 machines with
the same name on my network - it was actually a Windows 2003 and Windows
2008 machine. The 2008 was unable to ping by name (or at least the names of
other machines on the network). Check this and double check this as it
really did catch me out...

Failing this - basic DNS tests...

If you type IPCONFIG /ALL do you see DNS servers listed for the network
adapter? I would assume addresses here may well reference your router
(which is fine) or external ISP DNS servers.

If you don't see any, or the addresses look wrong, go into your network
adapter properties and make sure you have your DNS servers to be obtained
from DHCP too - they can (and I have seen) them be different where a machine
gets an address from DHCP and DNS are manual.

Let me know,

Regards,
Jon

I did look and no names on the network are alike. After looking
deeper ipconfig /all indicated netbios over TCP IP was disabled. I
looked at the adapter settings and it was set to Default (which should
enable it). After some research I found a key in the registry was
missing something (how this happend who knows).

HKLM\System\CurrentControlSet\Services\nbt\Parameters - This section
contains an object called TransportBindName and it was set to
nothing. It should be set to \Device\
This would cause ipconfig to see it as disabled enenthough it looks
enabled in the adapter settings.
