Enabling Java scripts and Ajax in IE for Windows Server 2008 R2

I had a problem while run the PerformancePoint Server 2007 Dashboard Designer using Internet Explorer in Windows Server 2008 R2. That is the Run button and the Go button are not visible for the Dashboard Designer page.
Also I had some problems for the SharePoint Server 2007 in the same OS and with the same browser. In sharepoint, those javascripts were not working.

Those errors occurs due to the security settings provided by the OS.
To solve those issues go to the Server Manager.
Then as shown in the below figure, you can find Configure IE ESC under the Security Information.



Click on it and select Off form those selections as shown in the below figure.



Then click Ok and check your sites.
It will works...
