Multiple Unidentified Network problem...

Hi there! I am using w7x64 with a dial-up network connection.My problem is that beside the fact that the LAN connection shows my network to be unknown that my pc is adding new public networks on his own naming them Network 2,Network 3 etc from thin air.They appear to be in use so i can't manualy delete them... My internet connection works! I need advice how to configure my LAN connection to stop adding new public networks.
I want to say that i already installed the Reliable Multicast Protocol and this didn't solve my problem.(I did this after a tutorial for my kind of problem that sayd this should do the trick)
Thanx for the help in advance!
