authentication problem with activex

Im 'using javascript and ActiveX EngineManager and ActiveX ImageViewer to connect the server XProtect Express 2014

The activex version are:

EngineManager: 3.8.0.3

ImageViewer: 4.1.1.0

The autentication mode is 0 (basic)

When I connect from IE11 from a Windows PC inside the same domain of the XProtect server: it’s all ok

When I connect from IE9 from a Windows PC not in the same domain of the XProtect server, i cant connect to the camera

I see the following error message on ImageViewer:

Connection refused. Reason: Invalid pre-6.0 token,

do you know I can solve this problem?

Thank you

Please check whether you have msxml4 in that PC. Msxml4 is a requirement when you run the active-x and must be located at the client PC.
