Just for general information, port 135 is used by the Microsoft File
and Print Services.

Basically it runs SMB over NetBIOS, which is run over TCP/IP (NBT).

Anyways, 135 is where NT listens for requests for files and printers....

(BTW, other ports are used in the same range, 136 and 137 I believe, but
they may be UDP...)

And yes, it does appear to be a problem and does appear to peg the CPU
load at 100% and it DOES affect the system, this is specially noticeable
on a slower system.
