RPC Server is Unavailable on debugging remotely

Hi, I`m having this issue trying to debug an application on a mk3100 with wince7, if I connect the device to the laptop via USB I can debug normally, but I need to debug remotely but everytime I get this message: 'RPC SERVER is Unavailable, Device not ready', is problem with my network , or is in my configuration to debug on win ce7?

 

Thanks in advance for your help.
