I opened up event viewer and i saw this message.
"The system detected that network adapter \DEVICE\TCPIP_{B9B65-994D-42E6-A81D-530CCF77} was disconnected from the network, and the adapter's network configuration has been released. If the network adapter was not disconnected, this may indicate that it has malfunctioned. Please contact your vendor for updated drivers."
Is that the cause and how can i fix it ? thx for taking ur time to read all those newbie's stuff.
