We service a number of clients networks using Remote Desktop Connections - generally a very easy access. Today I was unable to log into a server at one site, but as they were having a number of issues, I wrote it off as a specific company problem. Now I am unable to access our largest client network - using any of our remote software. I cannot ping, attempts to run a trace route fail immediately - while I can reach any other customer networks. I am totally baffled, can't even think of what else I can do to troubleshoot......help?
