NAT Network & Host-Only Network

Neil Waldhauer:
Your TCP/IP and adapters look fine. You only show an error restoring connections after logon, which is a PEER problem.

All you are showing is that a problem occurred.

ppgrainbow:
So, if the issue is a Peer problem after login, then should I post the contents of the IBMLAN.INI file located in the \IBMLAN directory and the PROTOCOL.INI file in the \IBMCON directory file that causes OS/2 Peer to not work when it is connected to a Host-Only Network on lan1?

Dave Yeo:
Yes, it is a good start to post them. Odds are that it is a problem with Windows wanting a newer peer protocol

The VSWITCHx is the protocol driver for Connectix Virtual PC, by the way.
I really love how copying and posting contents from the OS/2 Warp 4 guest to Windows 10 host works with the VirtualBox Guest Additions for OS/2! :D
I just did a recent backup of my hard disk images that contain the OS/2 Warp 4 installation just in case anything goes wrong. 8)
Update: I did manage to pull up the Windows NT 4.0 VM and for some odd reason, that OS can access the OS/2 drives over the network as mentioned in the screenshot below, but the OS/2 Warp 4 VM can't seem to access it the other way around. The computer name is VBOXWARP4.
So, it appears that something could be amiss with the settings in the IBMLAN.INI file.
