Here is some output today from the command line on Windows XP. I’m not going to add a lot of commentary here, but I thought this was a little ironic / funny.
U:\>net -help
The syntax of this command is:

NET [ ACCOUNTS | COMPUTER | CONFIG | CONTINUE | FILE | GROUP | HELP |
HELPMSG | LOCALGROUP | NAME | PAUSE | PRINT | SEND | SESSION |
SHARE | START | STATISTICS | STOP | TIME | USE | USER | VIEW ]

U:\>net send -help
Sending files is no longer supported.

More help is available by typing NET HELPMSG 3777.

U:\>net helpmsg 3777

Sending files is no longer supported.

Thank you. I love redundant messages.
