Error in query execution from Query designer

Hi,

We have recently installed the BI 7 server, when i execute the query from query designer i got the following URL:

http:///irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?QUERY=TEST_REP&VARIABLE_SCREEN=X&DUMMY=2

due to that page is not displayed, i guess there is some sort of hostname setting need to be done.

Can anybody please guide me where all these settings are done, help required urgently ?

Thanks in advance
