My business software just moved to the "cloud." It is working better than expected except for my computer. We use Windows Remote to connect. After 10-15 minutes of idle, I receive a Windows 2003 splash screen that says access is locked (I am actually connecting to a Linux mainframe, but had Windows 2003 Sever before the switch). The 2003 server is still in my office for other purposes, but I am told that we are no longer running through it. The actual business software program has a separate 2 hour idle lock that does not use the same splash screen. The computer that has the problem is a Windows 8.1 Samsung slate table. My other wireless tablets and my desktop do not have the same problem. My IT provider says that the problem is being caused by IE11, and they do not have a fix, except to recommend going back to IE 9. I have 10 other computers that run Windows 8 (not 8.1) with IE10, and they do not have the same problem. I would hate to have to go back to Windows 7 in order to run IE9. Any suggestions.
