We just tried it and saw the same behavior. The RPC server
(rpcss.exe) process is what consumes the CPU, however it doesn't seem
to affect the performance of the machine.
We couldn't find any mention of this in TechNet.

Subject: FW: NT4 bug? Or bug in my hardware?
Can anyone confirm this? On an NT4 server (maybe workstation too, I
don't have it to try),
if you telnet to port 135, type a bunch of junk (say 10-20
characters), hit enter and disconnect,
the server's processor utilization will go up to 100%!!! The only fix
I found was to reboot.
I tried with and without SP2.....same result. The installation is
'out of the box' with standard
default install options, of course including TCP/IP. I have no other
NT4 servers to try this on
and was wondering if I could get someone to try and confirm this
.....
Luck
