Windows 7 64 bit not responding to ping

[albertwt]

Hi Everyone,

Can anyone help me in diagnosing this problem please ?

when I tried to ping my newly setup host called host1 from local cmd prompt, it returns IPv6

when I ping from the DNS server, it returns public IP address of host1.com not the internal IP address ?

when I tried to ping the internal IP address from anywhere (host1 or other server) it replied fine.

this is DHCP assigned client, on the Windows Server 2003 DNS server console, ican see it is registering successfully but not in the DNS.

is there anything that I can or need to do to make it ping able using host.domain.com ?

the Antivirus is running and not blocking ICMP packet and firewall is managed by Symantec End Point AV

Thanks.
