We have 2 servers. When we download a web page with our ActiveX control from one server, the OCX file is correctly identified as signed from us and then installed. When we do the same thing from another server, we get the "control name is not available" message in the new browser bar at the bottom. The control can still be installed but the message looks bad. This just started with IE9. Why is this happening? How can this be fixed?
Can you run WinVerifyTrust against the signed ActiveX on the machine that has the "control name is not available" problem and check what is the result of validating the publisher of the ActiveX?
