I am running Win 8 on a laptop. My laptop connects to the corporate network through RDC. At work, everything works great. At home, using the same laptop, I establish a VPN tunnel to the corporate network and that enables fine. But when I launch RDC to connect to the corporate network through the VPN, it doesn't connect and times out. It gives me the generic error that the RDC service is not established. I thought it would be my wireless network in my home, but the same error happens when connected directly through an Ethernet port on the back of my FIOS router. Any suggestions?
