this file name in the related bookmark plugin-dlls entry.

2. Download msrdp.cab and save in your local system (such as C:\rdp)
3. Extra msrdp.cab file.
4. Go to command line and navigate to the extracted file location, e.g: C:\rdp\msrdp.ocx, run this command to
register it as "regsvr32 msrdp.ocx".
5 Restart the IE browse and try again.
6. If the above still doesn't work, go to registry by making sure the key is
point to the right file: Start->run-> regedit :
