winchat
There is an application in XP that allows networked users to to communicate with each other. It is a very simple program located in the Windows System32 directory. A search for "winchat"
will also bring it up. This program can be very usefull to users that work in large office complexes and need to deliver a message to another individual quickly and efficiently. This application also has a real time chat screen, so you can see the other person typing. I have tested this program on 2 computers running XP Pro, not XP Home.
1 start, search, "winchat" (or find in Windows, System 32 directory)
2 right click and select send to desktop (for easy opening)
3 run the program
4 choose dial button at the top
5 choose the computer of the person on the network who you wish to talk to.
6 both users must agree to connect to each other to talk.
