Thank you all, but that didn't work.
I unshared/shared a couple folders off C:\ but that didn't make any difference. I made sure Everyone is in both permissions.
I created a new temporary folder off C:\ and shared it, but that didn't work either.
I've disabled the firewalls on both computers and that didn't work.
I've rebooted several times.
I've flushed DNS on both computers.
I've read somewhere else that deleted the network and re-creating from scratch may work. What do you think? If so, how do I do that?
I've also read that removing the wireless/network adapters in Control Panel and letting Vista reinstall may work. ??
I'm getting desperate.
Thanks again.....
