TCP traffic can't be routed from guest to host on Windows hosting Solaris 10 on Virtual PC

I boot the machine and immediately issue a ping command to the VPC guest OS (Solaris 10). I use the ping -t 10.3.6.63 (windows) command so that the ping continues on the windows machine.

This is what I get "Reply from 10.3.6.63: Destination host unreachable."

I log in to开发者_StackOverflow中文版 the solaris desktop and realize that my domain name was not resolved it is now at "unknown." I ping my host machine from the guest machine and immediately I get the pings to succeed on the host machine. If I continue to let the ping continue the connection remains stable and I can connect to some services on the guest machine from the host machine.

If I disable the ping service the connection will eventually die. My Oracle client will say connection refused for example.

I re issue the ping command notice that I get "Reply from 10.3.6.63: Destination host unreachable" again.

This time I cannot ping from the guest OS. So I run an arp -d uspqlnb339 (domain name of host PC) and then re-issue the ping command from the guest OS; it succeeds and the pings start working.

What is causing this network path from being disrupted?

I run snoop on the guest account and I do see a lot of failure from the DNS server serving my host machine. For example

"DNS R Error: 2(Server Fail) unkown -> uspqlsv131 DNS C _nfsv4idmapdomain Internet TXT ?"

Perhaps this is a DNS issue. Is there any way to turn this off on Solaris 10?
