I have 4 computers in my home network, 2 with Vista ultimate X32 and one XP Pro. Within my own network, I can RD into 2 of them from my Win7 X64 machine. One of the 2 Vista Ultimate machines I cannot get into. I get to the point where It asks for Username and Password, then goes to the next screen and says "Username or Password incorrect". I have searched the web and this forum. I have seen this is a common complaint but have found NO solution, and I have tired all solutions I have read about. Which includes verifying I am putting in the correct username and Password. None have worked. I am what you would call an intermediate user and understand many aspects of a networking and computers but I am now stumped with this problem. I need HELP!
