I am using different RDP clients to connect to a Windows 2008 R2 server. I am finding that certain keyboard keys are not working properly. For example, when I try to type a "b" into a notepad document it closes out the Notepad program. It is though the "b" key on my keyboard is mapped to something else. I am not using any function, command, or option keys. I find the behavior is occurring in three different RDP clients. Any thoughts on what could be causing this?
