Network Access and Workstation: Weird Problem

Hello,

I'm having a weird problem over my network. My internal network has 6
sites link together by WAN links. My biggest site, in term of employee, has
about 100 workstations, mostly on XP. Most of the files of that site, reside
on 1 server. I'm having 2 DCs in there also. That site has also a backbone of
1 Gbps and workstations are accessing the network at 100Mbps speed.

That being said, usally during the morning around lunch and at the end of
the day, all my workstations are experiencing a strange phenomenon in that
site only: The workstation becomes unstable. The Explorer.exe stop responding
for about 2 minutes making the stations useless. Sometimes, the running
Office 2003 applications crashed during that "brownout".

I'm suppecting some tasks running on our file server, but so far, nothing
is schedule. I've looked at the activity of other servers and nothing odd.
All my LAN equipments are working fine.

What am I missing in that problem? I don't know what to look at to stop
this issue. Does someone had that problem too? What can make the Explorer.exe
process unresponsive?

Thank you

Fred

Hi,

Do you deploy updates via WSUS?

If so, then last weeks svchost.exe *fiasco* may be your problem. The fix is
to load 2 updates.
Then somehow get your users to follow this process.

My users are clever and managed to load the 2 updates from a network share.
I gave them all specific instructions in an email.
I could not be bothered automating it. :-) May be req, for 100 users
though.....

This is roughly what I told them:
1. First you need reboot and login. Then as *fast as possible* stop the
Automatic Updates service before your PC becomes unusable.
Start / Run -type in -> net stop wuauserv and click ok.

OK now relax...


1) You need to download and install the new update client:
http://download.windowsupdate.com/v7...gent30-x86.exe

2) Then this patch:
http://support.microsoft.com/?kbid=927891

After applying the above updates - svchost still runs high CPU usage
*but* not 100% only 88 - to 97 % and drops down more often. The PC is
quite responsive compared to the old 100% lockups.
