Accessing DELL PowerEdge 2950 server via iDRAC 5 console using Internet Explorer 11 – console top menu is not active. i.e. if you click on Macros, nothing happens. I believe the same issue affects Internet Explorer 10.

To resolve I had to enable IE Comparability View for the iDRAC IP address. In Internet Explorer 11 this can be done via: Tools > Comparability View Settings.

After this, top menu was working fine. 

Update

On some machines adding DRAC IP address to compatibility list was not sufficient. In these instances I also had to add the same IP to Trusted Sites. This can be done in Internet Explorer > Internet Options > Security.
