Repost from yesterday, but the matter is getting urgent now and i need new
light shed!

I've got a process svchost.exe [description below] and it is using more and
more of the my SBS2k3's CPU

I am getting warning messages every few minutes saying: "The processor is
experiencing a low level of idle time. Consistently low levels of idle time
can cause performance problems." Which is not a suprise seeing as svchost is
using 99% of the CPU.

SBS 2003 Standard
P4-3ghz @ 800Mhz | 1GB Ram
Pagefile: 887mb
store.exe is at 300mb
Additional software: MySQL & Norton Antivirus Corporate Edition

OFFENDING PROCESS @ 99% of CPU
svchost ["BITS, Browser, CryptSvc, dmserver, EventSystem, helpsvc,
lanmanserver, lanmanworkstation, Messenger, Netman, Nla, RasMan,
RemoteAccess, Shedule, seclogon, SENS, ShellHWDetection, winmgmt, wuauserv"]

server set-up has not changed - norton antivirus / mysql are not to blame, I
cannot find any clues in the event logs, concidered the fact that I could be
logging to much in the event logs [noting that "EventSystem" is listed
above, so I turned off practically all monitoring, to no avail. Restarted
the server a couple of times, within an hour or so svchost is back to 99%.
RAS is not being used, neither is the "companyweb" or any other local site.

I'm thinking that it could possibly be a something to do with Networking,
possibly NAT, it has translated over 10 million packets in the past 15 hours
& has a approx 950-1000 mappings running.

Can anybody shed any light?
