SUMMARY
Internet Explorer Service Pack 1 changes the method the Wininet.dll file
in Internet Explorer uses to resolve Internet Protocol (IP) addresses to
Web addresses. Internet Explorer uses the Wininet.dll file to retrieve a
list of IP addresses from a multihomed server or a Web farm. The
Wininet.dll file retrieves this list from the multihomed server computer
or Web farm by making a GETHOSTBYNAME call to the computer or Web farm.
The Wininet.dll file receives the list, randomizes the list, and then
attempts to connect only to the first IP address.
MORE INFORMATION
Internet Explorer Service Pack 1 changes the behavior of the Wininet.dll
file. Once the Wininet.dll file makes the GETHOSTBYNAME call to receive a
list of IP addresses, it does not randomize the list before the
Wininet.dll file attempts to connect to an IP address. The Wininet.dll
file attempts to connect to each IP address in the list in the order in
which they are returned by the GETHOSTBYNAME call. The Wininet.dll file
can also optimize the order it processes the addresses based on the IP
route table.
A multihomed server is a computer with two or more separate network cards
that can be assigned different IP addresses.
