Good ASP backdoor?

["Lachniet, Mark" <mlachniet () sequoianet com>]

Can anyone suggest a good backdoor for placing on a IIS server when you
can upload a file to document root?  For exapmle an all-in-one tool with
upload, download, command execution, etc.  There are several basic ones
out there - I was wondering if anyone ever wrote a really spiffy one.

Thanks in advance,
