I'd try creating a HOSTS file which points moneycentral.msn.com to
127.0.0.1

For XP, that files is in your \Windows\System32\Drivers\etc folder.

I would like to be able to block Money 2006 from accessing
moneycentral.msn.com at all times. It is a pain to have to wait fo it
to play games accessing when I start it. They only website I want it
to access is billpay.msn.com when I authorize a payment.

I don't want to kill my internet connection everytime I statrt Money.

I tried blocking access to moneycentral in the hosts file, but it
accesses anyways.

Please advise. Thanks in advance.
