Host Machine running Server 2003 sp 2 and VMWare Workstation 7.01.
Guest Machine is Server 2003 R2.
The Guest Machine can see (and be seen by) all computers on the network and it can ping (and be pinged by) the host, by name. The Guest Machine can also access all other shares on the network.
However, opening windows explorer and trying to access \\host\share (it's a good share that everyone else can see all over the network), times out.
Trying the NET USE command gets an error 67, network name cannot be found.
But pinging the host by name works.
