I use LogMein Free and Pro to support many customers. At one location I have a D-804HV Router that then connects to switches, then to servers and the rest of the clients. The clients and the servers all point to the Router to get Internet, but there is no DHCP. Everything is punched in. The DNS numbers are from the ISP not the router. If I remove DNS numbers from a NIC then of course the user or machine has no Internet capability, but can still function in the LAN environment. I need to always have Internet access on the machine so that I can remotely support them with LogMeIn. Logmein is just like Remote Desktop, but it allows the user to view what you are doing (very helpful in many trouble shooting situations).
Is there any way I can prevent access for the user i.e. IM programs and Web Browsing, but still have remote access through Logmein to support them?
