Hi Michael,
Quite a few Windows servers I am monitoring show such "Local Area Connection* <N>" interfaces, which are not active interfaces on the system itself.
I didn't dig too deep into it, but made a guess that these are probably inactive networks that Windows has saved somewhere (e.g. a different network connected during server setup or similar). The only thing in common was the "*" in the name, so I filtered those out using a script in Hook::CreateInterface in the Script Library.
In our case, I did the same for isatap and Teredo (and a few other) interfaces, as we don't need to see those either.
See below for an example using the three interfaces mentioned above:
if ( $1->name ~= "^isatap" ) return false;
if ( $1->name ~= "^Teredo" ) return false;
if ( $1->name ~= "\*" ) return false;
return true;
Cheers
