Context:

• 3 HyperV guest images (DC, SQL, MOSS)
• 1 internal network
• 1 domain (PJM.COM)
• DC: 192.168.0.192
• SQL: 192.168.0.153
• MOSS:192.168.0.160

I am having communication problems from/to the MOSS machine from the other two. I removed the MOSS machine from the domain and cannot rejoin.

When I ping the MOSS machine from DC, I get the following response:

Pinging MOSS [192.168.0.152]
Reply from 192.168.0.192 Destination host unreachable (4 times)

When I ping the MOSS machine from SQL, I get the following response:

Pinging MOSS [192.168.0.152]
Reply from 192.168.0.153 Destination host unreachable (4 times)

From the MOSS machine, I can ping the server names, however I cannot ping the FQDN.

When I ping from the DC and SQL machines, I get IPv4 addresses. When I ping from the MOSS machine, I get IPv6 addresses.

I'm a developer and don't know what steps to take to resolve this issue. Please help!?
