Narrative:
In position for takeoff; just as we started to roll and attain takeoff thrust we got an anti-ice master caution so we aborted. Abort speed was 20 KTS. Due to taxiway closures due to snow we had to taxi to the far end high-speeds to exit which caused a go around for someone on final. As we exited we looked on the overhead to see what anti-ice light was on and none was on nor could we recall anything. I had an idea that it was the cowl anti-ice light since it did not occur until takeoff thrust. I was unable to do a high power run-up on the taxiway due to poor braking. Since we could not ascertain exactly what we had; we taxied for takeoff again. Checked holdover times and a wing inspection. As we started next takeoff and achieved takeoff thrust we got a master caution and a cowl anti-ice overhead light and aborted at 70 KTS. Rejected takeoff never engaged. Checked brake cooling and it was in limits. Taxied back to gate.

Title: B737-300 FLT CREW INITIATED A REJECTED TKOF FOR AN ANTI-ICE WARNING. LIGHT EXTINGUISHED AND ANOTHER TKOF ATTEMPTED. THE SAME INDICATION APPEARED; RESULTING IN ANOTHER REJECTED TKOF.
Narrative: IN POS FOR TKOF; JUST AS WE STARTED TO ROLL AND ATTAIN TKOF THRUST WE GOT AN ANTI-ICE MASTER CAUTION SO WE ABORTED. ABORT SPD WAS 20 KTS. DUE TO TXWY CLOSURES DUE TO SNOW WE HAD TO TAXI TO THE FAR END HIGH-SPDS TO EXIT WHICH CAUSED A GAR FOR SOMEONE ON FINAL. AS WE EXITED WE LOOKED ON THE OVERHEAD TO SEE WHAT ANTI-ICE LIGHT WAS ON AND NONE WAS ON NOR COULD WE RECALL ANYTHING. I HAD AN IDEA THAT IT WAS THE COWL ANTI-ICE LIGHT SINCE IT DID NOT OCCUR UNTIL TKOF THRUST. I WAS UNABLE TO DO A HIGH PWR RUN-UP ON THE TXWY DUE TO POOR BRAKING. SINCE WE COULD NOT ASCERTAIN EXACTLY WHAT WE HAD; WE TAXIED FOR TKOF AGAIN. CHKED HOLDOVER TIMES AND A WING INSPECTION. AS WE STARTED NEXT TKOF AND ACHIEVED TKOF THRUST WE GOT A MASTER CAUTION AND A COWL ANTI-ICE OVERHEAD LIGHT AND ABORTED AT 70 KTS. RTO NEVER ENGAGED. CHKED BRAKE COOLING AND IT WAS IN LIMITS. TAXIED BACK TO GATE.
