On your Vista machine, go to the Network and Sharing Center and for your network
click on View status. A pop-up dialog will appear. Click Properties. Another pop-up
dialog appears. Click on Internet Protocol Version 4 then select Properties.
Under the General Tab, check that you have "Obtain DNS server address
automatically" rather than using a fixed address that is outside your
own intranet which may have changed.
If it did have a fixed IP address, jot it down and using the web browser interface
to your ADSL box, login as the administrator and check what DNS address it was
assigned to see if was the same. In any case, whilst there, make sure that the
ADSL box has been configured to obtain DNS automatically rather than a pair
of fixed Primary and Secondary DNS addresses that may have been given to you
before, you set once, forgot about but now your provider has changed.
If you use a DHCP sever where you use fixed addresses anywhere in a hosts table,
make sure that two machines have not been assigned the same IP number or
that any fixed IP numbers aren't falling into the range of any that the server
has been set to deliver dynamically.

Your ISP will be able to provide a recommended value but sometimes
if it is set too large, things can go amiss with packet fragmentation
handling which one can only spot by running an Ethernet packet
sniffer.
For example, if your MTU is set to 1500, you might try a lower value such
as 1492.

Sorry, where are these settings found..?
