When attempting to download a file using Internet Explorer 8, the application associated with the file starts twice. For example, if you attempt to download a .doc file, Microsoft Word may launch twice. This may occur when all of the following conditions exist:
The SmartScreen filter feature of Internet Explorer 8 is enabled
Internet Explorer 8 cannot connect to the SmartScreen online service
Internet Explorer 8 Protected Mode is not enabled. Note that if Internet Explorer 8 is running on Windows XP or Windows Server 2003, the Protected Mode feature is not available
When you download a file using Internet Explorer 8, a SmartScreen filter for the file is activated. As part of the SmartScreen filter processing, Internet Explorer 8 tries to connect to the Microsoft server urs.microsoft.com over TCP Port 443. If Internet Explorer 8 cannot access urs.microsoft.com, Internet Explorer 8 launches the file's associated application twice.
To workaround this problem, use one of the following methods:
Method 1: Add the file download site to the local intranet zone in Internet Explorer
This method adds the file download site to the local intranet zone file after you download the necessary source settings.
Start Internet Explorer
Click the Tools menu button, then click Internet options
Click the Security tab
Click the Sites button to point to the local intranet zone
Click the Advanced Settings button on the local intranet screen
Type the address of the site you want to download the file(s) from, and then click the Add button
Click Close, then Ok, and then Ok.
NOTE: After downloading the file, you may consider removing the site from the local intranet zone in Internet Explorer.
Method2: Troubleshoot internet connectivity to the SmartScreen online services.
Troubleshoot any network connectivity issues that could be prohibiting you from connecting to the internet.
