If you trust this Web site, you can lower security settings for the site by adding it to the Trusted sites zone. If you know this Web site is on your local intranet, review help for instructions on adding the site to the local intranet zone instead.

Important: adding this Web site to the Trusted sites zone will lower the security settings for all content from this Web site for all applications, including Internet Explorer.
If you click Add, click Add two times, and then click Close, you can create the data access page. However, when you next start Access and create a data access page, you receive this message again.

If you click Close, you receive the following message:
Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly.
When you click OK, you receive the following error message:
The data definition of this data access page has been corrupted and can't be repaired. You must recreate the page. Save has been disabled.


This issue occurs because of the increased security introduced in Microsoft Windows Server 2003. The data access page must load ActiveX controls to function. However, it cannot load these controls if your Internet Explorer Internet zone security settings are set to High.

After you click Add on the message described in the Symptoms section of this article, and then click Add to add the accdp protocol to the list of trusted sites, you are prompted again to add this protocol the next time that you create a data access page because the number that follows accdp:// changes each time you create a data access page.


To work around this issue, change your Internet zone settings in Microsoft Internet Explorer to allow ActiveX controls and plug-ins. To do this, follow these steps:
  1. Start Internet Explorer.
  2. If you receive a message stating that Microsoft Internet Explorer's Enhanced Security Configuration is currently enabled, click OK.
  3. On the Tools menu, click Internet Options.
  4. Click the Security tab, click Internet, and then click Custom Level.
  5. Under Run ActiveX controls and plug-ins, click Enable.
  6. Click OK, click Yes to confirm that you want to change the security settings for this zone, click Apply, and then click OK.
