Sneak Preview WAS & EP60_SP4 - Issue

I installed the sneak preview of WAS server with EP60_SP4.The installation went thru

successfully.

After the installation i am able to login and i get the "Portal Content" page

(path:: Content Administration->Portal Content)

But when i try to access any of the other menu options( and sub menu options ) namely the

"User Administration" or "System Administration" or "Welcome" pages the content is not

getting loaded and all i get is the "Loading" message(with the animated icon)....it goes on

& on.

but the menu options in the top right hand corner namely "Help" , "Peronalize" , "Logoff"

work.

Eventhough i am unable to do anything in the EP ( http://<server-name>:50000/irj )

I am able to delpoy and run "J2EE Engine Examples" from the WAS home page

(http://<server-name>:50000)

Has anyone encountered this problem before ?

Any ideas about how to troubleshoot this issue ?.............where to look & what to look

for.........any suggestions ?........thanks in advance
