There was a guy at our office that was extremely proficient with Netware, so much so that if he got physical access to a Netware server, he could press the special 'Admin key sequence' (from memory it was about 4 keys pressed at once on the keyboard) and then he would issue commands to peek into memory and tell you the Admin password. This trick only worked if you had already unlocked the screen console with the Admin account since the server booted, but it showed us very early on how important physical security to even a keyboard was.
I do remember a key fight that happened back then with Netware and Microsoft was how Netware gave you a free 2 user license to a server if that server was only running network services, such as maybe a DHCP server. If you wanted to do file sharing, then you had to buy the appropriate user license.
Microsoft introduced the ability for a Windows NT server to mount a share locally where the contents of that share was data from a Netware server. This way you could get a free 2 user Netware server license, have the NT server use one of those licenses, and then hundreds of people could access the data without Netware being able to technically block it.
I recall (can't find any images on the Internet to back it up) that Microsoft changed the traditional 'hand under a folder' icon for this feature so that if you looked carefully, the hand had it's middle finger extended.
