King + 2 knights sufficient for mate !!!
Sort:
As you all can see in the game above.. i am left with 2 knights and a king against my oppoent's king + rooks and two pawns. My opponent blunders in the end and decided to let his time run out.
Suprisingly, i was awarded a draw instead of a win !!! Theoretically my two knights are still capable of delivering checkmate if my opponent play not precisely. I hope chess.com will fix this bug.

It isn't a bug; that's how they programmed it.
Different organizations have different rules for what constitutes "sufficient material." For example, FIDE allows helpmates while the USCF does not. Chess.com more closely follows USCF rules, but with simpler rules to make it easier for them to program it in.
According to the article when they implemented it (http://www.chess.com/blog/webmaster/live-chess-gets-some-love), K+B, K+N, and K+2N count as insufficient material. Anything else counts as sufficient.
Disallowing helpmates is opening a can of worms...
This position is a draw if you disallow helpmates, but my guess is that if black ran out of time white would win? IMHO the FIDE rules make more sense in order to maintain continuity. If the theoretical opponent's skill level is not "as low as possible" then what is the opponent's skll level when determining what is a reasonable sequence of moves that could arise?

the position you posted would under FIDE rules be a win for white
under USCF rules a draw (I think)
under chess.com rules a win for white.
Not perfect in every situation but without an arbiter to call at least chess.com rules are certain.
That pawn and king VS kin is a draw by 3 times repetition or stalemate or white loses the pawn

The discussion is about sufficient material in a timeout situation. The board position is a win for white according to FIDE rules because it is "possible" for black to lose.
This site also would declare a win for white, because K+p is deemed sufficient material.
In fact, Black may be able to win by force in that position, given that White's having pawns actually removes his ability to conduct a stalemate defense. Black should blockade the f-pawn, win the h-pawn, and then try to confine White's king. Then, once the king is trapped, the blockading knight comes in for the kill.
