I am having trouble getting both dos and win-os2 sessions to connect to the internet.  I first noticed the problem trying to use a Win3.1 plugin, but I have done some testing and discovered that not even dos ping will work.  I have tried uninstalling and reinstalling OS/2 internet support, and the two necessary drivers are in my config.sys.  Also, I have the proper path and set etc statements in my dos autoexec.bat.  Also, in terms of Win-OS/2, I have only one winsock.dll file in the path.  I am using Injoy 1.0 to connect to the internet.  All of my OS/2 sessions have not problem accessing the internet.

Are you using OS/2 3.0 (aka Warp) and TCP/IP 3.0 or later? The TCP/IP RESOLV and HOST files for OS/2 and for DOS are kept in different places since the OS/2 TCP/IP and MPTN stacks were "converged". The OS/2 TCP/IP control info is in the \MPTN\ETC\ dir (RESOLV2 and HOSTS files) while for DOS sessions, the files RESOLV (no "2") and HOST reside in \TCPIP\DOS\ETC. These files are text files and con be edited. Try backing up the DOS RESOLV and HOST files and then copy the OS2 RESOLV2 file to the DOS RESOLV files and do the same for the HOSTS files.

If you're trying to go through a SOCKS filewall from WinOS2, down load the SOCKSCAP (16-bit) program from NEC's website. Good luck.
