Parallels 3.0 and Windows Vista VPN

I just purchased and installed Parallels on Mac OS X and I'm running windows vista business on it. I set up a vpn on the mac and windows sides. On both sides, I can ping all servers through my vpn. On the mac side, I can map shared drives. ON the windows side I can not. Does anyone have a clue on how to fix this problem? I am using a Verizon V740 aircard for a network connection.

Also, on the Windows side, Vista does not see the Verizon aircard. Is there a way for Vista running in Parallels to see pci-express cards?

I would be greatful for any advice.

 

Anyone????
