When you use Internet Explorer on a Windows XP-based computer, Internet Explorer may take 8 to 11 seconds to open a Web page

When you use Microsoft Internet Explorer on a Microsoft Windows XP-based computer, Internet Explorer may take 8 to 11 seconds to open a Web page on the first try. This delay does not occur on subsequent tries.

Note This problem may occur when you use Internet Explorer together with the Web Proxy Automatic Discovery (WPAD) feature.

When the DHCP Client service code first runs, it does not correctly process the Dynamic Host Configuration Protocol (DHCP) inform messages that are used by the WPAD feature. The WPAD feature uses the DHCP inform messages to retrieve information from a DHCP server. Therefore, Internet Explorer is slow the first time it opens a Web page that uses the WPAD feature. Subsequent delays do not occur because the information is retrieved and cached for later use.
