I have been trying to connect to my laptop and it says Cannot find host.
I am getting the ip adress from my router device tableAre you doing it by the documentation?
Connect to another computer using Remote Desktop ConnectionYes. I have it enabled and I have them on the network and i know the password! P.S. the  one im connecting from is windows 7 and the one I am trying to connect to is Vista.Are they both on the same LAN?  Or are you connecting from a different site?yes. they are all on the same router. (They are like 20 feet away from each other.)
In that case fire up command PROMPT on the laptop and enter "ipconfig", to double-check that you are in fact using the correct IP address.

After that, MAKE SURE that remote desktop is enabled per Geek's link above (see the section "To allow remote connections on the computer you want to connect to").Also check they are on the same workgroup - not completely necessary, but sometimes helps.

Both computers must have unique names. Do NOT depend on the IP address.Forget the IP address.  Can both both PCs see each other in "Network places"?
no it does not.
ill try

Both are discoverable, and they STILL wont connect!Good. So you have permissions.  -Right?

Did we  establish that you are NOT trying to get into a wimpy version of Windows 7? Read this:
