I used this Turn on Remote Desktop in Windows 7 or Vista - How-To Geek
tutorial in order to set up my Windows 7 ultimate computer to be a remote pc. At my job, I am trying to connect to my pc from Windows xp. I type in required ip, I do log on in Windows 7 log on screen where I can see two users, one is named "name", and the other one is my account. I chose my account, type in password, and then everything shuts down and I am unable to connect to my remote pc again.
My 3389 port is opened.
