iS2010 keeps shutting down WMFs from Linksys Unix Network storage, says it detected attack from it

when playing with windows media player only. This started just a few days ago after Live Update, always worked fine before.

I already switched the Unix box to Full Trust in the network list, don't know what else to do.

The IS error message says that it "matches the signature of a known attack". 

 

Windows Media Player is the prefered way to play since most of the media is high quality and doesn't play very well in other players.

HELP!
