The difference between hub/switch:
Hub: Data recieved on any port is broadcasted to all ports in a hub
Switch: Data recieved in a port is sent only to the spefic port it is destined to.
In a switch the speed could be better as data is sent only to the needed ports and not to all ports.
For a network in a house, with less traffic a Hub should do. With just 5 computers and application like yours there would be no difference. So i would suggest you could just go with a Hub.

there would no advantage of using hub or switch at a small network level of yours but if u are plaaning to use hub on price basis then u should go for a switch as there is not big diffrence in switch and hub .
the technical diffrence in hub and switch is , switch has a repeater while there is no repeater in hub , so switch has a advantage of fast data transmission , as the data in such small in not larce as in case of big and vast networks like 100- or more pcs. the switch basically smothens your network , but i would prefer u switch as there no price diffrence in it , so if u want increase number of pc u can have better hardware support support.

Hey,
Just recently loging off or shuting down my computer has starting taking a very long time. I am running Win2k and the hangup occurs when the box pops up that says "Saving Settings..." It takes anywhere from three to five minutes to get past this.
Any ideas on why this takes so long?
-Thanks

The normal cause for that is when you have your My Docs or some shared folder on a network drive. Windows will sync the folder contents at logoff time, and if you have many and/or large files, it will take a while to move the data over the network.

My computer isn't on a network. It just plugged directly into the cable modem.
Any other ideas?
If there is any information I could provide just let me know.

I find this happenning when a driver or service fails to respond to the shutdown message. When I see it happenning on a customer's system I usually can make it go away by removing and reinstalling drivers for various devices; video and sound cards are the most common problem devices. On my system I have an annoying bit of software from Creative Labs (DEVLDR) that delays the shutdown by several minutes, but I live with it rather than mess with the sound card. After all, I only shut down every three months or so...;)

Can this be true even if everything in device manager seems cool(no little yellow signs or red x). So you just reinstall all the drivers and it clears up.
"After all, I only shut down every three months or so..."
You must be keep a pretty tight ship for it to be running that stable. How do you do it .

Yes, it definitely can. Sometimes drivers/services seem to cease listening to their message loops, and appear to go to sleep, especially if you haven't called upon them for a while. I don't know the details, but I suspect that Device Manager only queries the device status as it is loaded and initialized. If that goes smoothly, it will report that everything is cool. If something subsequently fails DM will never notice it, unless you have asked it to perform an operation that fails to execute correctly.

I don't download cute crap that I don't need, and I accept most of the defaults suggested by Microsoft. They generally work well enough for my purposes. I've rarely had a failure caused by a problem in third-party software; only MS updates have killed my system, with the single exception of AOL's AIM application. Win2K is a remarkably stable platform, so long as you don't try to do anything outside of the norm.
XP is something of an unknown to me; I've never had it on a machine of mine, and can see no reason ever to "upgrade." My customers, however, are cursed with it, as most have purchased new PCs with it pre-installed. Working on their machines has given me enough experience to learn that I never want it on anything that I depend upon.

In my experience a clean install of XP is better than any pre-installed system I have ever seen. My XP box only ever shuts off for power outages and hardware maintenance. Though based on what I have seen of 2K (never had it on a machine of my own) there isn't a whole lot of benifit of upgrading a stable win2k machine to xp.

I used to face this problem too. My windows 2000 is working fine but when I install MCAFEE 7.0, I cannot shut down my computer. The message display that "Saving data..." and it still appear whether I keep my computer running one hours. If I remove MCAFEE 7.0 it can shutdown but it not properly too. Some people tell me that MCAFEE 7.0 replay winsock control and some network component, but their explaination seem not logic. Until now I cannot figure out the main problem.

Hi, I have a problem with the connection between my PC and its device. At home I have a printer HP 2200D connect to my computer via LPT1 port. When I turn on the computer properly and I turn on my printer later, the computer could not print and it said that there is no printer connect to the PC. My modem also have the same problem like printer when it connect to my PC via COM2. But if I turn on the printer/modem the same time that I turn on the computer start, everything is fine. I can print and access to the internet. Could anyone give me some idea about this problem?

Windows detects its environment at startup, and doesn't reliably notice devices added later on legacy ports. USB interfaces are designed to notify the OS on the fly when they are powered up, but the older interfaces - serial and parallel - don't always respond. Try turning on all of the connected peripherals before you start the computer. That should solve the problem.

This was an odd one that I hope someone can learn from. Today I had a call from a customer that was totally baffling. Her two CD drives in the secondary IDE channel went missing. My first thought was a loose cable, but reseating the cable didn't help. Second, though the odds are long against it, was that the drives or cable had failed. But the BIOS recognizes both drives perfectly; if the cable or either drive had failed that would not happen.
A bit of history:
Several months ago I replaced the existing motherboard, a PII, with a new, top of the line P4 with hyperthreading enabled. I know that it's bad practice, but I did it without reinstalling the OS - Win98 original. My reason at the time was that they had a bunch of software installed that they use regularly, but don't have the disks to reinstall. They also don't have a copy of Win98 in the office. I've had some luck doing this, but Win98 can't adapt to hardware changes very well and usually a full reinstallation of the OS is necessary to force redetection of the motherboard resources. On this occasion it worked, but the performance was terrible - the thing still runs like molasses in January. But it functioned, and the error messages that originally prompted the upgrade went away. Now, suddenly, the system can't recognize the drives on the secondary IDE channel. All of the drives are operating in "compatibility mode" which explains why it's still slow. But at least they were usable for several months, and I can't figure out what might have triggered the change!
My recommendation today was to bite the bullet, accept that they're going to lose data and the programs that created it, and install Win2K Pro on the thing. I just hope that they can still buy Win2K, as the primary program used by this PC will not run on WinXP. I'm hopeful that I can do this cleanly, without major problems, but this system seems to be cursed. IIRC, a clean installation only wipes out the C:\Windows folder, and it's just possible that the installation program and files for third party tools are in their own, separate folders. I sure hope so...
I hate it when I can't solve a customer's problem... It doesn't happen often - perhaps twice in ten years - but it still sucks!
The moral of the story is, I guess, that when it's best to do a full reinstallation it is better to accept the loss and do it early, than to wait until later and suffer poor performance until then. Some things just can't be helped, especially when you're dealing with people who really shouldn't be allowed to operate a PC without adult supervision.

Can you tell about her problem clearly? What she has been doing before she lose the CDROM drive? She just install windiws, or she play too much with some option in the windows or she just setup her CDROM drive (before she get that problem).
In my opinion, the following thing might relate to her problem:
1. Some one might be disable her CDROM from device driver tab of My computer property.
2. Someone might change the registry to hide her CDROM drive.
3. Her computer might inffect with some kind of virus that hide the local drive from windows explorer.
4. She might change some setting in CMOS not to detect CDROM.
5. She might set wrong jumper before she start to connect her CDROM with the system.
6. The driver of the CDROM is corrupted.
7. The mainboard might not compatible with her CDROM.
Note: all of these list is relate to my opinion and my friend problem. Please check it carefully and choose only the correct answer.

8. None of the above.;)
No one in her office has the ability or normal curiosity to even try changing a settings. No one knows where Device Manager is, or suspects that it might exist. No one has ever seen the back of a computer - they only know that they can be opened at all because they've seen me do it. She only does two things with the computer. She swaps email with her husband in the service, and tracks building permits on tribal lands using a proprietary software package, and that requires occasional backups to CD.
The good news is that, finally, her boss got permission to buy her a new PC today. The bad news is that the proprietary software won't work with WinXP.

How about step 3. Her computer might inffect with some kind of virus that hide the local drive from windows explorer. Is it possible that some drive in windows explorer are hidden by the virus?
In your opinion, what is the main problem that could cause windows explorer not display the CDROM drive?

Nope, the antivirus software is up to date and running. Besides, any "good" virus writer would hide the C: drive, not a pair of CD drives lower in the chain of value.
My first thought, and the commonest cause I've found, was that a cable had failed or come loose. This can happen even in a system that has not been moved or tampered with, because temperature variations cause minute changes in the components that can cause them to shift position and lose contact. Reseating connectors usually fixes such problems, or in the case of a failed cable, replacement clears up the problem.
Viewing the controllers in Device Manager reveals that there is a problem with the drive controller drivers - the yellow warning tag is displayed on all of them, which was not the case when I last saw the system. Win98 failed to detect that the hardware had changed, and kept both the old and new drivers so that each of the three entries in Device managers appears to have a duplicate installed. If I delete either of them, Win98 reinstalls it on the next boot.
The solution in this case, I'm certain, is to do a clean installation of Windows on the drive, which will remove all drivers and redetect the hardware. Unfortunately the data and programs on the system are critical, and cannot be replaced - none of the original CDs are available, and the backup device is the CD drive that has gone missing. Once the new PCs are available it will be a simple matter to move the data to a new system. Then it should be easy to buy a copy of WinXP and install it on the old machine. That, I expect, will clear up the problem and restore a very nice machine to full function. Of course, by then it will be redundant, having been replaced.

If the purpose of the machine is to use the software won't a new machine that won't have the software be of limited use ?
You should be able to copy the existing software and reinstall manually. It'll likely be a pain to dig through the registry, all dependant dll's, ..., but i've had fairly good success doing this in similar situations ... unless there is a license ... but even that can usually be worked around.
good-luck,

Hi, I used windows 98se and use dialup networking to access to the internet. Last month, dialup networking is working fine (I can access to the internet). But this month I could not access to the internet when I dial a connection. During I dial the connection it display error and close the connection and IE. I go to windows explorer and found the folder of dialup networking. I select on it to view the connection but after I release the mouse button the select move to My computer icon. I don't know what is the problem come from. I want to make some change to the configuration of dialup property, but I can't view the folder of dialup networking. Can anyone give me some idea or suggestion about this problem?
