I have been using Remote Desktop Connection (RDC) from my Windows 7 Professional SP1 desktop for several years to connect to my servers. Suddenly, perhaps after a recent Windows update, I can no longer do this. Instead, I get this message: "Your computer can't connect to the remote computer because a security package error occurred in the transport layer." (screen shot attached).
My online research mentions something about adding a key to the registry, but I'm hesitant to do so and thought I'd check here to see if others have seen this problem and get their solutions.
