As described in Prerequisites for using the OMI web client, before you can start the web client on any remote device, you must install a security certificate. We recommend that you export the security certificate from the SMS and copy the exported certificate file to the remote device. For instructions on how to export the certificate, see Export the security certificate.
After you have copied the certificate file from the SMS to the remote device, install it to the Trusted Root Certificate Authorities store on the device. The steps below are an example; the precise steps on your version of Windows may be different.
