This just started happening on a virtual machine that is dedicated to one user; she's been logging into it for months now with no issues, but today the error about "The Display protocol for this desktop is currently blocked by a firewall." came up. She also accesses a computer from a floating pool and has no problems with that one. I've gone into the machine as admin and can see nothing wrong; the only thing I did change was upgrade Symantec Endpoint Protection; we just underwent an upgrade to the server and clients and that machine was missed. After a reboot, the issue persists. I'm grasping at straws here because of the spontaneous nature of the error.
