I setup some Windows 7 64-bit clients. We are not using IPv6. I tried to ping, tracert these devices by their name. I get a General failure when I ping or tracert, instead of replies or hop info. I think the dns name is wrong. When I ran nslookup I see the following: C:\>nslookup win7-testbox Server: dc.domain.org Address: 161.168.1.153 Name: win7-testbox.domain.org Addresses: 2002:a1df:c3f4::a1df:c5f7 161.168.1.46 I am able to ping these devices from XP or 2003 devices w/o any problems. When I ping from a Win 7 to a Win 7 client by name. The name is resolving to the the first address listed in the Addresses field of nslookup. I can ping the second address in Win 7 to Win 7 when using the IP address. Because we use DHCP on our clients that address is not always intuitive. How to resolve this? Please help.

If you want to force a ping using ip v4 just type "ping win7-testbox -4"
