Legitimate DCE-RPC (MS DCOM) bind packets dropped by IPS
Symptoms
  • DCE-RPC (MS DCOM) bind packets are dropped by IPS.
Cause

The DCE-RPC protocol continues to evolve and new applications may extend or 'stretch' the understanding of the Security Gateway when it inspects the traffic. Since the Security Gateway may not understand some legimitate traffic, it drops the traffic.
