I have 2 windows 7 64bit machines connected to a time capsule. One connects to the time capsules drive without error. The other does not. Both get an IP address and are connected to the LAN and Internet. The error on entering the password on the machine that does not work is:
could not connect to the disk. Make sure NETBIOS is enabled and try again (53).
I have both network adapters setup exactly the same way.
