to build the NetSend.exe NetSend send message to target computer use 135/udp
just like "net send" provide with nt/2000, difference: many times, fake source For 2000 only. In nt4, it does work, but
1. it request the true source,
2. stop for a while to send next message to the target, Even if u use "net send".
3. use computer name and cannot use ip.
All these will happen Error 2273. So don't use this on NT4 Notes: If u don't want this to bother u, just stop Messenger service
use: net stop messenger
--- [email protected] Win2000 pro/server only store 26 new messages,
and u can press ENTER(keep it, not release) to eliminate received messages.
(2K Adv server store more than 200, and cannot use pressing ENTER to eliminate message)
So u maynot use NetSend as a flood-tools.
