Hi, i have a problem here, i have three comps in my house. it's all connected via an access point. I usually use it for sharing my internet connection and my files. The problem is, i can't send messages to my other computer. I tried to use "net send" from the command prompt, i always display error message. i also tried to use messaging program, but all of itu requires somekind of domain. my network does not use a domain. just a simple computer networking. can anyone help me? Thank you.
