I have two QNX4 vmworkstations on the same WinXP host and have been unable to get the network to communicate. Neither 
the QNX network or IP network.
Have multiple QNX425 standalone machines that network just fine.
Also have QNX6  and SuSU linus vm workstations on same host and they communicate via IP just fine the rest of the world.


Have VM network set up as Bridged and all VM have static IP addresses assigned.
Any ideas ?
