There are a lot of unchecked buffers in FTP.exe (client) try:

C:\>ftp
ftp> put
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
[....]

I tried this, win2k 5.00.2195 / IIS 5.0 FTPd and got the same results

C:\>ftp localhost
Connected to localhost.
220 Microsoft FTP Service (Version 5.0).
User (localhost:(none)): test1
331 Password required for test1.
Password:
230 User test1 logged in.
ftp> put AAAAAAAAAAAAA

[.....]

AAAAAAAAAAA<CR>

C:\>

Event Logs show the following

Application popup: ftp.exe - Application Error : The instruction at "0x77f8c493" referenced memory at "0x41414145". The memory could not be "read".
