Data access page question

I've created a data access page that has a chart on it to provide a visual to
my managers & directors. I have the DAP uploaded to my company intra-net. I
have a link to open the DAP to view the chart. Before the chart will open I
and my users get 2 messages;

"This Website uses a data provider that may be unsafe. If you trust the
website, click OK, otherwise clcik Cancel."
after clicking OK;
"This website is using your identity to access a data source. If you trust
this website, Click OK, other wise click Cancel."

After clicking OK the chart comes up and the user is able to view the data
and use the chart as it is designed.

My question is, how can I suppress the 2 message and just have the DAP open
upon clicking the lin kto it? Is this a security setting on Access or the
browser?
Can anyone help me out or at least get me pointed in the right direction?
Any help is greatly appreciated.
