This problem occurs when some software is incorrectly integrated with network interfaces on low level. Examples of such software are firewalls, proxies, traffic managers, etc.
You should use latest version of such software. WinGate is most common cause of this problem. If you are using WinGate, you should upgrade to WinGate 5.0.6 build 820 which has this problem solved. Older WinGate versions had errors which prevented Radmin from operating properly.
It also seems that installing Radmin first and then your current WinGate version could be a solution if any problems occur.
If updating to latest version doesn't solve your problem, you'll have to disable it.
