I truly doubt you are running a DOS network stack. I haven't seen that outside of a lab or classroom in many years.
In other words I think you are chasing the wrong issue.
Recently started using our older computer again. Upon startup I get the error message 7308 that the computer can't find device driver protman.dos. I searched the computer for it and found it in C:\Program Files\America Online 7.0\net\Win98SE. Did a little research and found out that the file belongs in the Net8.cab file in Win98. So I found the Net8.cab file (which was zipped,) so I unzipped it and tried to move the file over, but it wouldn't let me. I get a message saying that I can't add to CAB files, and that protman.dos isn't a CAB file, and something about UUEncode, which I know nothing about. Is there a way to move the file, or is there a way to work around it? The computer seems to work ok, and I'm connecting to the internet ok. So it's not really interfeering except that I get the annoying message. Thanks. Ed.
