  • 1. Mobil User Best Practice Question
    I have a laptop that is used off site. I have been using RWW into my SBS 2003 standard with two NIC's, static IP. I need to install the client part of Trend C/S/M for virus protection and keep that updated. Should I join the laptop to SBS using the remote or roaming template? I don't need document redirection as all company data is stored on the server through drive and/or folder shares. If I do join the laptop, dumb question but, when I logon when it's not connected, do I logon to the local machine or use the choice in the dropdown for the server? I'll also at times be using a dialup connection to RWW when broadband is not available. Also, RWW and OWA question. RWW seems to be the option of choice for me and works quite well. What would be the need for OWA, or am I missing something? BTW, all the support in this news group has been just fantastic, without this source, I'd be toast! Thanks, Bob

  • 3. SBS2003 - reconstruct default web page in IIS
    Hi, I am working with a SBS2003 Basic installation (on a 2003 AD native DC). I just tried installing CRM Professional Suite 1.2 onto the server - pointing the connector to a seperate Windows 2003 Server with a copy of SQL2000 server aboard. The glitch came when I allowed the default installation to point to the default web page (companyweb). Upon restart, I received 403 forbidden errors from the default page (while logged in as the domain admin). I looked into security and found permissions correct (user and IP). At some length, we decided to uninstall CRM - and apparently blew out the companyweb page. Does anyone have a KB on reconstructing the default web page for SBS2003? Thanks, C.
  • 4. Outlook 2003 not connecting
    So I just upgraded one of my clients from SBS2000 to SBS2003 and now Outlook 2003 will not connected to the exchange server. Outlook XP and below connect just fine, so I had to downgrade the version of Office on all the employees in the company. (Everything below is done on a local LAN, no RPC over HTTP or anything else.) When I go to set up the account it does a "Check Name" just fine. When you start the program, however, it gives the useless error of "Unable to open your default e-mail folders. The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance." If I put Office XP on the same machine it loads up and everything is peachy. I get no event log entries on either the server or the PC, making troubleshooting that lame error pretty much impossible. Obviously some sort of security settings or something have changed in Exchange 2003 and Outlook 2003. Whoever set up the SBS 2000 at this client in the first place obviously didn't know what he/she was doing from what I've seen in trying to clean it up, so I have no doubt that there are settings set wrong somewhere on the server, but I have no idea where to even begin to look. Anyone have any sort of idea as to how O2K3 and E2K3 communicate? If I knew the differences between O2K3 and OXP I might be able to figure out where the problem might lie. Thanks, Randy
  • 5. sharing SMTP?
    Hi I've asked this before and had good replies but need more help please! We are using pop3 and SMTP connectors on our sbs2003 server for our emails. However, there are 2 of the employees who dont want to join our exchange Server and prefer to carry on using pop3 and smpt from their outlook directly to the ISP. But the problem is we all use our internet domain for our emails. Since we had the exchange, the exchange users cant send emails to the other 2 users outside the exchange and we get failed emails error. Obviously exchange is trying to locate the other 2 users inside the exchange as they have the same email domain, rather than treating the emails as usuall and sending it to our ISP SMTP mail server. I had a look at SMTP sharing article 321721 . It tells you how to set up a secondry SMTP server for failed emails, which is what i think i need, but unfortunately thats when exchang uses SMTP virtual server, not the SMTP connectors, which we are using. FYI, there are 2 SMTP policies in our server: and min.local I hope i was clear enough. Does anybody have an idea??

Next time I will capture what you are looking for.

I have Process Explorer (SysInternals) running
In the interim, when it pegged, I killed the capture agent, but the CPU load
continued and the process was queuing.dll!Dllinstall+0x1cf37

Does this help narrow the problem

Thx for all your help.

hat's a dll related to windows update, that's about all I know. Whether, or
how, it's related to your issue isn't known, though.

The output from tasklist would be more helpful, to me at least.

Here is the readout you requested

A long list. When I kill wuauserv, wuaueng.dll kicks in. When I kill that,
theystem stabaizes.

I reapplied and it still pegs. This occurs on only one of my PCs
(unfortunately - mine). I will reformat C: drive and re-install XP SP2 and
see if that clears it up.

Thx for your help.

1.svchost process (for update service) hogs CPU process

2.svchost process spike cpu 100 %

I have read the previous posts and am not yet getting a solutions t our 
Here is our situation.:
We rolled some windows updates this week on XP pro SP3 machines via WSUS.
Since then most machines on the network are staring up and then the SVCHOST 
process grab the cpu to 100% for about five minutes then it releases and the 
machines in question will work for sometime and then the svchost process will 
fire again.
I have noted also that outlook seem to be most affected application it 
freezes up when this svchost begins it's cycle.

I did a tasklist and found that on all these machines this process controls 
the following process:

svchost.exe                 1072 AudioSrv, BITS, Browser, CryptSvc, Dhcp,     
                                 dmserver, ERSvc, EventSystem, helpsvc,

Any ideas on the way forward?


3.svchost.exe - Using 100% of CPU after boot till I End Process

My svchost.exe is taking 100% of the CPU after boot. I'm lucky if I can even 
get into the Task Manager before my mouse freezes up with a nice little beep 
associated with the freeze. After numerous "slow" restarts, I can get into 
the Task Manager and end the process > svchost.exe > SYSTEM and the computer 
will go back to a normal CPU and things work again.

I have read many different articles and many say to turn off Windows Auto 
Update -- I have done this.

I use Spyware Doctor / AVG Free / XoftSpy  -- I have tried disabling them in 
the start-up menu...that doesn't seem to help. Anyway, I'm stuck and 
frustrated with the svchost.exe deal!!!

As an added FYI - svchost.exe is listed 12 times in my Task Manager (7 times 
with the word SYSTEM by it  -- 3 times with LOCAL SERVICE by it -- 2 times 
with NETWORK SERVICE by it).

I did try and install WindowsUpdateAgent30-x86.exe  and when I run it it 
says "Install is not needed since WIndows Update Agent is already installed."

Any help on this is appreciated.

Thanks much.

4.100 % CPU and svchost process


My PC is always running at 100 % CPU and is slow.
When I kill the process svchost process, the system comes back to normal and 
I can run all of my applications.
I have run all the spy, virus, performance software, but can not find 
anything wrong.

I have read that killing the svchost process is bad but it seems it is the 
only temp solution I have.

Any recommendation?

5.SLOW notebook, CPU at 100% all the time, explorer.exe hogging CPU

 	Using an Inspiron 2200. I have a 1.4GHz processor (Intel Celeron M). I use
WinXP Home. 20GB hard drive (I know it's small but I have 300+ GB worth of
externals, but that's besides the point, or is it?). 1.24GB of RAM. I have
every spyware and adware program on earth (the legit ones like Ad-aware and
Spyware Sweeper) and I run them regularly. I have a paid subscription to
Norton Internet Security, and I use it. I defrag and empty my temp files
regularly. I usually have Adobe Photoshop CS2 (and work with very large
graphics), Microsoft Outlook, AIM and a web browser or two open regularly
with my high speed internet connected. Task Manager tells me on average I
have 35-45 processes running at any given time.

My CPU usage is usually at 100%, which is NOT right. In task manager the
process that is hogging anywhere from 95-100% of my CPU is explorer.exe

EVERYTHING I do lately takes forever to load, and sometimes just locks up.
Especially when using Outlook, and when loading large files into Adobe. It's
getting really bad and I don't know what to do to speed things up. Buy and
install a better processor? Is it a virus? My drivers? Should my on-board
hard drive be larger? Memory optimizer programs don't really do the trick,
but something tells me that my memory isn't a problem and that it is my CPU
and explorer.exe
