The DCOM exploit that is floating around crashes the Windows RPC service
when the attacker closes the connection to your system after a successful
attack. Best bet is to assume any occurrence of crashing RPC services to be
signs of a compromised system until proven otherwise.

I'm showing signs of an RPC sweep across one of my networks that's
killing some XP machines (only XP confirmed). How wide spread is this at
this time. Also, does anyone know if this is just generating a DOS
symptom or if I should be looking for backdoors in these client systems?
