Have problem as above. Vista Home Premium 32-bit.
I understand my ISP only uses IPv4 - Virgin Media www.virginmedia.com
Anyway, name resolution does not work in Vista.
I operate a LAN behind a router - GTA GNAT 3.42.
This is merely a debian linux router kernel with features like
HA (high availability et al). I use a PIII Coppremine, 512MB,
CompactFlashCard with linux image, 3Com 10/100 PCI on the
public interface, 4 Port SMC 10/100 and 2 Port Intel Pro/100.
I have no problems with Win2K and Win XP Pro.
I can ping and tracert domain name(s) with no problems (Win2K/WinXP);
such as www.ntlworld.com
Unable to do this in Vista.
Disabled Vista Firewall for testing.
Disabled (unchecked) IPv6 and discovery components on network connection.
Disabled IPv6 in registry with DisableComponents FF patch
Disabled IPHelper service in services.
Disabled DNSClient in services (to eliminate cache issues).
Tried another NIC in the PC, a 3Com with correct drivers.
Still cannot resolve domain names but get IP addr etc.
Removed 3Com NIC.
Onboard NIC - nVidia - Vista installed nVidia driver at install.
As boths NIC fail DNS resolution, assumed not a NIC issue.
Network Type - Workgroup (not connected to domain).
The IP address details are all allocated by the router.
Use DHCP on interface.
No WINS server
Node Type - Broadcast
ran ipconfing /all
Get IP Address ok.
Reports default gateway Address ok.
Reports subnet mask correct
Reports DHCP server Address ok.
Reports DNS server Address ok.
Note! - the router above is configured to forward DNS requests to ISP DNS
Getting IP address ok - no problem there.
Can ping loopback.
Can ping allocated IPv4 IP address.
Can ping default gateway.
Can ping DHCP server.
Can ping DNS server (forwarder on router).
Can ping external IP address. I have tried 126.96.36.199 this relates to;
Get responses ok.
Tracert works ok with sample address above.
Try to ping www.ntlworld.com
or any other domain name, times out.
The network has been configured as local only (for now)
Symptomatically, AVG Free 8.5 via the update option does appear to
connect to the update server to the extent the updates are made
available via a dialogue box, when I try to DL these, update fails.
Issue remains DNS resolution.
Any advice? Wireshark?
