The dcom rpc Vulnerability bring great damgae to a host,when we use the exploit to test the Vulnerability,the service of the host will be crashed or we will get a shell.
But ,these result is not what I want.
I want to make a tool to scan,to test whether a remote host has the Vulnerability or not,whithout crashing the services or getting a shell.
Can I?and how to do?

Sorry for my poor english.
