Vista - Can't establish a co adhoc networks and limewire connection is blo

Hey all

This issue is regarding with p2p connectivity

It seems that i cannot establish a connection in an adhoc infrastructure, i
cannot ping any computer in the adhoc network. But other programs such as
browser and msn messenger can connect.

I also have another issue regarding it, i cannot connect to any p2p
application such as limewire, kazaa , etc. WHy does this happen? Is i because
windows blocked p2p connection or is it because hardware or software error. I
tried to reinstall the driver also the software utilities of the wireless
device.

Can somebody help me please!
