## Symptoms

- SmartView Tracker logs show that DCE-RPC traffic on High Ports is dropped, although a rule with the *ALL_DCE_RPC* service exists.   

Dropped traffic:  

* DCE-RPC
* WMI
* SCCM

## Cause

Possible reasons:

* The DCE-RPC traffic is matched to a rule that allows traffic on TCP port 135 or TCP port 111 and located above the rule with the "*ALL_DCE_RPC* " service.  

* The RPC initiator (traffic on TCP port 135 or TCP port 111) must pass through the Security Gateway on the "*ALL_DCE_RPC*", so the session "real" traffic on the higher port will pass.
