Explorer.exe crash using direct cable conn

I'm trying to do direct cable connection with Windows XP. When I
create new connection as follows:

start->control panel->network and internet connections->create a new
conection->set up an advanced connection->connect directly to another
computer->host,

after completing the process, when i would right-click on the Incoming
connections icon, select Properties, and then tab Users, Explorer.exe
will crash. It has something to do with "mprapi.dll ", but I forgot the
error numbers (0x??). on the other machine it works properly. why does
it crash?

thanks in advance
