Detect CIS ports

This detects the CIS ports by connecting to the server and processing the buffer received. CIS (COM+ Internet Services) are RPC over HTTP tunneling and requires IIS to operate. CIS ports shouldn't be visible on internet but only behind a firewall. If you do not use this service, then disable it as it may become a security threat in the future, if a vulnerability is discovered.
Disable CIS with DCOMCNFG or protect CIS ports by a Firewall. For more information about CIS:
