Traffic Blocked Notification: MSLLDP.Sys

  • 1.  Traffic Blocked Notification: MSLLDP.Sys

    Posted May 13, 2018 03:44 PM

    I keep getting a windows notification that "Traffic has been blocked from this application: MS Link-Layer Discovery Protocol Driver (mslldp.sys)."

    I have a user-defined exception for C:\Windows\System32\drivers\mslldp.sys, but that hasn't done anything. 

    I followed http://www.symantec.com/docs/TECH203497, and even with the "Allow All" rule at the top, I get the notification.  

    What's the next step to isolate?
