Hi guys... I have a typical problem in my office. I have 5 desktops and a laptop. The laptop and 3 desktops run on Windows 7 Professional 32 bit OS. All are connected in lan vai a Cisco 8 port Ethernet hub. A UTSTARCOM DSL modem is connected to the ethernet hub. All systems can access internet by manually dialling using a PPPOE dialer. All Sytems except the laptop and one desktop can connect to internet. but my laptop and one desktop is unable to connect. I reinstalled the OS in both and also resetted the winsock. Its makin weird

.. Pls help
