What manual?  Do you mean the help page?

Read the CHANGES file and switch to internet2.dll.  Sorry, the docs
got left one step behind when late in the day I switched the defaults.

It will not open an Internet connection.  The following saying that your
DNS is not finding the site.  I suspect you need to open a connection
first.  Personally I detest programs that make connections without asking.

Don't expect too much: an awful lot of this part of Windows does not work
as documented on Windows 2000.  You should be able to switch to
internet2.dll and make use of your proxies.  However, I changed away from
that last week as on a very flaky connection, it was a lot less reliable.
