MS CRM 2011 blank page with script error

Hi,

We are getting blank page after installing the MS CRM 2011 in windows server 2008 R2 while accessing both default organization and Organization imported from crm 4.0 getting script error.

<Message>Error initializing component with element id='null' and with type='null' : Object expected</Message>

we checked the authentication under ms crm website,anonymous, windows and asp.net impersonations are enabled

Could you please help on this to resolve this issue

Thanks

Rajesh
