Problem checkup network(check_ad)

I am pluging performed various tests including the network that calls netdiag(check_ad). I get one event of warning for the miniport Wan.
Is there any way to disable this test to Wan or any solution for not having the event of the warning?

GetStats failed for ‘Paralelo directo’. [ERROR_NOT_SUPPORTED]
GetStats failed for ‘Minipuerto WAN (PPTP)’. [ERROR_GEN_FAILURE]
[WARNING] The net card ‘Minipuerto WAN (IP)’ may not be working because it has not received any packets.
GetStats failed for ‘Minipuerto WAN (L2TP)’. [ERROR_NOT_SUPPORTED]

Or can i disable this test in my pluging???Thanks
