This exploits a buffer overflow in the request processor of

the Internet Printing Protocol ISAPI module in IIS. This

module works against Windows 2000 service pack 0 and 1. If

the service stops responding after a successful compromise,

run the exploit a couple more times to completely kill the

hung process.
