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.

Solution:
Disable CIS with DCOMCNFG or protect CIS ports by a Firewall.
