Services.exe spikes to 100% cpu

[Guest Craig]

[Win2k Sp4, updates current as of 13 Sep 07...p4 2.8GHz, 1GB RAM]

 

Howdy;

 

Can anyone point me in the right direction to resolving this? Articles

I've found on MSDN and past postings here refer to a fix...from a couple

of years ago yet my system's up-to-date. Any leads would be

appreciated. Details below are gleaned from Process Explorer v10.06.

 

thx,

About every 30 minutes, services.exe spikes to 100% of cpu. The thread

is listed as services.exe+0x85f7 and is initiating a UDP session w/a

local address of "clientname:bootpc." The spikes last about 30 seconds

apiece.

 

This is on a LAN with 3 (DHCP) Windows clients, a (fixed IP) NAS and two

(fixed IP) networked printers.

 

Services registered to services.exe are:

 

Dhcp

dmserver

Dnscache

Eventlog

lanmanserver

lanmanworkstation

PlugPlay

ProtectedStorage

Wmi

During a Spybot Search & Destroy v1.5 install, the script also installed

Spybot's own HOSTS file (can't remember if it was a user-selectable

option).

 

At 175KB and over 6,300 lines the Spybot HOSTS file caused my dnscache

client to time out repeatedly but not before sucking out ever last ounce

of my cpu's strength. It was the events log that really helped me zero

in on the problem...

 

Btw, I could've also solved this apparently by disabling the dnscache

client instead <http://support.microsoft.com/kb/245437/EN-US/> and then

re-enabling the HOSTS file. If anyone's read this far and has an

opinion as to which represents a better security profile, please chime in.
