In Network and Sharing Center in Control Panel, what are your options set
to? Make sure it is configured like this:
- Network discovery: on
- File sharing: on
- Password protected sharing: on
Also, if you have any other security software installed, make sure they are
not "protecting" you by blocking file sharing.
With these options set, you should be able to have read-access to a shared
drive that you have configured through advanced sharing in the drive
properts screen, after authenticating with your Vista computer. You will
need to assign your user account a password if it does not have one in order
for it to work properly.
