rdc

So I want to use remote desktop to another computer in my household, i've tried connecting to it on different ports but to no avail.

i can connect to the computer running at port 3389 fine, and i'm sure the computer is running the rdc server normally. already port forwarded, and i've connected with com2 plugged in directly to the router.
