I was a largely MS-DOS and Windows 3.1 user in the 1990s, but in late 1998, I found that I hated Windows 9x. I felt like the days of my completely controlling computers were starting to slip away. I also had ambitions to be a Network Administrator pst High School. So on a 25 Mhz 486 SX I installed a very Rudimentary thing called ZipSlack. My first experiences on the Internet were on a Tandy 1000 TL using a Dial up PPP Connection. I found out that ZipSlack could emulate/simulate the PPP Connection and NAT my Tandy over the Tandy's Remaining serial Port. When I didn't need the Network connection, I could reboot into MS-DOS 6 and play my DOS games.
Fast forward to 2000 and I found out that my new Mandrake Linux 7.1 Pentium 200 that replaced that 486 could not only NAT Internet connections, but using a software called Mars NWE, simulate a Novell Netware Server and provide logins to DOS Computers, and Windows 95 machines alike. It wasn't very stable, but it worked to my astonishment. Months later that became a Samba 2.0.6 Domain controller. Combined with seeing KDE 1 at the time and I was like "This is the future"
The Domain created by that 2.0.6 Domain controller still exists to this day, running Samba 4.1.19.
