Hi everybody ! Here's the situation that I'm in , I successfully connect my laptop to my pc through bluetooth to share the network resource on the pc , and I also enabled the multiple user feature of the windows xp system on my pc. Then I tried to set up a Remote Desktop Connection to the pc . But, the network connection lost before I could log on successfully . In this case , after I restored the bluetooth connection from the laptop to the pc , I tried to set up another RDC from my friend's pc which's wired-connected to my pc .The RDC is successfully setted up but the bluetooth connection between my laptop and by pc was lost again . Could anyone help me out ? I need to set up RDC to my pc from my laptop through a bluetooth network . BTW, both my laptop and my pc have a windows xp professional running on each on them. Er..... I have solved the problem myself. It's about the driver of the bluetooth. It works when I replace the driver with the default microsoft version.
