You can check if it is an IE problem trying to access it with a different browser.
Can you open it when you are logged in the server ? ( using http://localhost:4780/qmc )
If the problem is just in a different machine, you need to check firewall restrictions on port 4780
Hope this helps for now...
yeah i did try with firefox as well, and nothing changed and both won't work with url you gave me.
It 's pretty bizarre, because, just before installing this SBE(V10) , I had the very same SBE(V11) and everything worked fine.
For many reasons , i did this downgrade, and suddenly the management console disappear.....
