You're right, practice in class is not enough. Sadly, many of my students can't afford a computer at home and so have only my class to use for practice. I strongly encourage them to read the subject chapter before class so I can give only a brief lecture and maximize the time they have to get their hands dirty. It's really the best way to learn!
Since you're going to be studying networking, invest now in a cheap hub/switch for your home and practice setting up your home net using the various protocols in Windows. Check into the Resource Kit tools available on the installation CDs and online at MS TechNet, too. Learn to use the command line tools efficiently and you'll be far ahead of many networking "professionals" I've known. You can have hours of fun using ping, tracert, net, route, and other built in commands, as well.
One of the hardest concepts for my students to master is IP sub- and super-netting. Heck, some days I confuse myself on that subject. But it really is fundamental to modern networking and rather fun! If you're going to do any pre-class studying, that's where I'd focus. You won't suffer from that bunny-in-the-headlights dazed feeling that many of mine get when we hit that chapter.
Enjoy the course!

Thank roger, I might find second hand computer to learn with it. In my country (Cambodia) the second hand computer is very cheap (around 120$), but I never heard about second hand hub, router, switch... I might check on the market whether it is available or not. I want to setup a small professional networking at home to learn and gain the experience as much as possible.
Thank you very much for your adivce, During the class if I have any problem I will post it out and share it with the other. (Especially you!!!  )

I use outlook express 6.
Try the menu Tools | Options, go to the Security Tab, and uncheck the "Do not allow attachments to be saved or opened that could potenially be a virus".
Hope it helps.

Hi, my organization use mdaemon to manage mail server. Before, we use windows nt server 4 to use mdaemon and use e-mail as normal. But today we install win2000 server and reinstall mdaemon. The problem is relate to the mail that we send from hotmail or yahoo to any address within the organization. But all of e-mail account in our organization can send to each other within the network. When we try to test at the server it display "ERR authorization failed". So we could not send or get any message to the other people.
Does anyone could give me some idea or the solution to solve this problem?

Hi, support that I have peer to peer network for 5 computer. The first computer name "A" and the second computer name "B". The first computer contain three user account such as "a1", "a2" and "a3". The second computer contain three user account too such as "b1", "b2" and "b3". I would like to ask you, how could I get the user name from computer "A" and display it on the screen? I don't want to use any third party software. I just want to get it via windows function. Is it possible? I don't mean that I don't hack the other computer but i want to share some resource to match the user name on the other computer.
Remember: only get the user name, not their password.

I have zonealarm installed and of course everyone knows, the vsmon services is basically the brains behind the outfit...anyways when I look at the services applet and go to options on vsmon almost everything is grayed out...so I went into the registry at
hkey_local_machine\system\currentcontrolset\services\vsmon\security
And in there, is a key called Security...It is a binary key and has a whole bunch of hex written in it. I imagine this is what is causing the services applet in XP to gray out all the configuration for it. Is there a way I can find out how to write my own Security reg keys like this for other services to keep people from tampering, etc?
P.S. I've already "googled" the matter lol but maybe someone knows the answer elsewhere. Thanks in advance.

It's the Access Control List for the service object. You can view the ACL for a service using the sc tool:
C:\>sc sdshow w3svc
D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)
(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)
(A;;CCLCSWLOCRRC;;;AU)
(A;;CCLCSWRPWPDTLOCRRC;;;PU) This output is in Security Descriptor Definition Language [SDDL] format.
To set the ACL on a service from code, use SetServiceObjectSecurity. From the command line, you can use sc sdset.

Hi all. Our Exchange server is Exchange 2003 running on Windows 2003 Server. The client machine in question is running Windows 2000, SP3, and Outlook XP (10). The problem I'm having is that his Outlook client isn't publishing his Free/Busy information to Exchange, despite the setting being set for 6 months worth of data. I've ran Windows update and Office update, uninstalled Office, ran RegClean, and reinstalled office, all to no avail. I know it's Outlook, and not Exchange, because an article on the net suggested deleting the user specific Free/Busy entry on the exchange server, and Outlook would rebuild it. I did this with my own account, and indeed, my Free/Busy entry was recreated. Not so with this particular user.
Any ideas? Thanks in advance.

You know how sometimes just talking a problem out helps you solve it? Case and point. I went back down to the users machine and deleted his Outlook profile, then rebuilt it. I assumed (incorrectly apparently) that the profile would be deleted when I uninstalled Outlook. It wasn't. Either way, this fixed the problem. Apparently something in his profile had been corrupted. Weird.

Hello,
I'm not sure if this is a hardware or software problem. But it only happens
in the Windows environment. What happens is the PC turns off power to the
monitor and CD drives after booting up to the logon screen or sometimes I
can get past that and actually get into Windows before it goes to sleep. It
acts like when the power saving options are set to turn off the monitor at a
certain time. I checked that when I could get on and it wasn't set to go off
for 30 min. I then turned it off all together. I also set the BIOS back to defaults.
After it goes to sleep, the PC is still on and the HD light is still on,
but after it goes to sleep, I can't move the mouse or strike a key to get it
to wake up like normal. I have to power it all the way off and restart it.
It sometimes will not even get to the logon screen before clicking off. It
just almost makes it to it. Very intermittent lately to when it goes off.
But, I've noticed it's doing it more often now where I can't get on at all
most of the time.
I've tried to reformat the HD and reinstall XP thinking I had a virus or
something. But, once I get into the XP windows looking setup screens(after
the first install restart) it blinks out again. It won't do that when I am
in the beginning DOS looking setup XP install screens. I even tried my
WIN98 disk and got through the whole install before it decided to blink out
again.
Other things I've tried - another video card in another PCI slot.
Does anyone have any suggestions? Is this enough information?
Thanks
Lance

Hi, I used to have a problem like you too during the last 2 years. I found this problem because my monitor is too old (more than 4 years). I think the performance between the vga card and monitor is no more compatible together. Try to check vga card, or if you have a friend try to exchange your monitor for a while. If it has the problem it might become vga card, or if nothing problem it might become your monitor.

Thanks for the response Roath. The thing is, I've already tried 2 different monitors and another PCI video card with the same problem resulting. But, I might just try a brand new video card... not sure what to do at this point.

First off, boot into SETUP and disable all power saving features in the BIOS. Some BIOS types are not compatible with Windows. Let Windows manage the power, or disable it, too. While you're in the BIOS settings, check to see if the 'PnP-aware OS' option is enabled. Although I rarely need to change the default, on rare occasions it helps to set it to Yes. If this doesn't work, try moving the video card to a different slot. It really doesn't seem like this kind of problem, but you never know. Not all slots on the PCI bus are necessarily Bus-Mastering, and video cards need this capability. If you can, also try monitoring the case temperature. Though unlikely in this situation, since it shuts down so fast, sometimes excessive heat can cause the video system to shut down.

Thanks Roger. I will try those suggestions as well in the next day or two and post later on how it went.

I would like to start using the Windows XP CD writing system but there's one problem with it. It always has to make a copy of the files being written to the CD before using the copies to actually burn the CD. If there are lots of files or large files then this additional copy process can take a long time.
Most CD burning apps just use the original files during the burn.
Is there any way to make the Windows XP CD writing system use the original files during a burn ? If so, how ?

When i am registering a dll (regsvr32 /i au_setuph.dll) in my system, it is giving the following error in a message box.
"DllRegisterServer in au_setuph.dll failed.
Return code was: 0x83100001."
But the same dll, i am able to register in another machine.
Can any one, tell me what that return code (0x83100001) meant for.

All I can suggest is asking the vendor. The 0x310 facility code for HRESULT isn't defined anywhere in the Windows headers.

Hi. Everytime I login to Windows (XP proffesional, btw) my internet explorer´s start up page is one that I never knew of, and is actually one that I don´t really like... what´s going on?

It sounds like some program is running on startup which is setting the start page. I suggest getting hold of Sysinternals' Autoruns[^] program to check what's running at startup.
You could also try one of the anti-spyware programs, such as Ad-Aware.
If you suspect a virus, you could try AVG Free Edition[^].

Thanks Mike, the 'AutoRuns' did work perfectly, and I found a very suspicious .js file running at start-up wich I deleted from the start-up process (it was c:/windows/tlc.js).
I´ll tell you if it really worked after I re-boot and see the results.

Sure, you have a virus in your computer. This virus name trojan.horse or backdoor (maybe). My computer at the workplace is inffected with this virus too. To solve it, first disable system restore in the windows registry, then run your computer in safe mode and start norton (if you use norton anti-virus) to scan for an inffect file.

But we have a problem with the virus in our network. The space of internet usage is increase everyday among 400MB. I know that virus always send something to the internet from the client but I don't know which client. Do anybody know any tool/utilities that will put on the server to record all an activities of the user machine that route the signal to the internet? (I need the utilities that record the url, ip address, the size of the page and summary for each user every one hour or half an our).
One more thing, I heard my friend told me that proxy server also record all an activitie of the user to the internet. Is it possible to do that? If yes, how could I set up proxy server on my server?
Please help, urgetn!!!
