ping latency question

Hi Experts

We have a WFP callout ( ALE connect and ALE Recieve and TCP inbound and outbound ).

Based on WFP inspect sample.

Few symptoms on customer machine:

–> During network file copy on machine where WFP callout ( based on WDK inspect ) is installed,ping latency is observed.

–> Also ping latency is observed intermittently.

–> If WFP callout is removed then ping latency is not observed.


–> ping sends ICMP.How then WFP inspect effects ping latency.I could easily verify that during ping no traffic hits callout functions.

–> How to troubleshoot ping latency issues.How can I debug machine sending ping response.What kind of trace I can enable.
