NS.exe is using all CPU power

A

Arne And

Hi

Got a Win2000 domain with 4 win2000 server running. (all with sp4 and fully
patched)

One of my server is very slow. Everything is taking loong time to do, if am
gonna see the taskmanager.

In Taskmanger I see that NS service is taking allmost all of my cpu power.
(the server is running a 2 CPU with 1.3 GM RAM)

When I stop the NS service the CPU drops to normal (a few %) but if I start
it again the CPU go`s in 100%.

Why is this, and how can I fix it?

It worked fine for a few days ago, and I havent dont any changes with it.

Am allso running Norman Antivirus for a few years, and that has worked fine.

-regards

1) Download the following three items...

Trend Sysclean Package
http://www.trendmicro.com/download/dcs.asp

Latest Trend signature files.
http://www.trendmicro.com/download/pattern.asp

Adaware SE (free personal version v1.05)
http://www.lavasoftusa.com/

Create a directory.
On drive "C:\"
(e.g., "c:\New Folder")
or the desktop
(e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

Download SYSCLEAN.COM and place it in that directory.
Download the Trend Pattern File by obtaining the ZIP file.
For example; lpt265.zip

Extract the contents of the ZIP file and place the contents in the same directory as
SYSCLEAN.COM.

2) Update Adaware with the latest definitions.
3) If you are using WinME or WinXP, disable System Restore
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
4) Reboot your PC into Safe Mode
5) Using both the Trend Sysclean utility and Adaware, perform a Full Scan of your
platform and clean/delete any infectors/parasites found.
(a few cycles may be needed)
6) Restart your PC and perform a "final" Full Scan of your platform using both the
Trend Sysclean utility and Adaware
7) If you are using WinME or WinXP,Re-enable System Restore and re-apply any
System Restore preferences, (e.g. HD space to use suggested 400 ~ 600MB),
8) Reboot your PC.
9) If you are using WinME or WinXP, create a new Restore point

Hi

Yes, it worked. And it was the W32.Gaobot worm that took all the CPU
(ns.exe)

Thanx. It took some time to clean 2 server. But what i dont understand, is
that both are running antivirus, and they are fully patched and with the
lates SP. How can Gaobot infect my 2 servers then, when it uses the network
to spread????
Must send a harsh e-mail to my antivirus provider, to hear what they have to
say.

I allso found the source, and tomorrow am gonna beat up that mother*****
that put his laptop on my LAN without asking me at first. AAAAHHHHHHH. I
have been working for allmost 24 houers now, and am just going through with
one last viruscheck.

Anyway.

Thanx Dave. You saved my day.

-Regards
