Networking / NAT Network & Host-Only Network

I'm having problems trying to get OS/2 Warp 4 to communicate with other two other VMs on VirtualBox - Windows NT 4.0 and Windows 2000.

How can I get OS/2 Warp 4 to communicate with the Windows NT 4.0 and Windows 2000 VirtualBox VMs with the Host-Only Network adapter? Would I need to check the setup.cmd file in \MPTN\ETC to see what could be amiss here?

So, how is everyone today?  :)
