I have 4 machines that I am trying to set up to log into remotely from off site. I can log into all of them from onsite, and I can log into at least 2 of them from offsite (there is 1 that I have not had the opportunity to test). I have my router set to forward the ports to the ip addresses coming in on different ports. For example, coming in to my static ip on port 1234 is forwarded to the ip address for computer 'A' on port 3389. This works perfectly for 2 computers, not the other computer. I have been working around by logging into 1 from off site and then remotely logging on the computer I want. What might I be doing wrong?

Are you sure you are forwarding the port to the right address and that the computer has a static ip? – lopsided98 Apr 17 '13 at 21:26
It sounds like you understanding port forwarding, just double check that you have the ports and IP addresses forwarded properly. – Keltari Apr 17 '13 at 23:26
Are the security settings the same for the working and non-working computers. Specifically, does not non working one have Network Level Authentication enabled – Scott Chamberlain Apr 18 '13 at 3:38
Also windows has separate firewall rules for RDP for Public and Private/Domain networks. Could it be that the external connection getting blocked under the Public rule but Private/Domain rule is letting the other computers connect? – Scott Chamberlain Apr 18 '13 at 3:40
lopsided98 & Keltari, I have double checked and triple checked that I have the correct forwarding ports and static ip address. Scott, the Network Level Authentication was a problem I did have on the first computer, so that was one of the first things I had checked (good advice though). The firewall rules sounds promising. The computers I can log on to have the same virus/security software, and the problem computer is different. Thanks! – Andrew Apr 18 '13 at 15:33
