SAP NWBC 5.0 PL5 Security Popup issues

Hi Experts,

We installed SAP NWBC 5.0 PCL5 and we are using SAP GUI 7400.1.2.1102. When we try to connect to our systems we are getting the security certificate alert.

Can any one tell us how we can make this message no to appear.

I am getting this on Windows 7 32-bit OS with IE 10.0.9200

My JAVA is Version 8 update 66

I selected view certificate and also did install certificate but still I am getting this popup for all my systems.

Please advice.

Thanks

GP
