How are your computers configured? What is the new Internet connection? At a minimum, all computers on your peer-to-peer network must have IP addresses in the same subnet, and all must belong to the same workgroup. If you use static addressing, check to see that your PC is configured the same as the rest, ie the same subnet and workgroup, and no duplicate addresses or host names. If you use dynamic addressing (DHCP) make sure that all are configured to obtain addressing information automatically. Usually you want to configure your Internet router/modem to act as a DHCP server and disable any other DHCP servers on the network - there can be only one. You mentioned some reconfiguration near the server - if they replaced a hub with a switch, it can take some time for the switch to fill its routing table. This should not take more than a few minutes, though.
BTW, if you have 25 computers on a peer-to-peer network, you're exceeding the recommended maximum by quite a chunk. Installing a real server and switching to a domain architecture may seem expensive, but it will save you money in the long run.

My computer has been switching off for no apparent reason every once in a while, usually with a funny burnt metallic smell coming out of the box. This is obviously a problem, but what?
I'm pretty sure there's a problem with the powersupply, possibly the cooling fan, since I'm also hearing a funny grinding noise down there.
Any hardware gurus out there got any suggestions? Please let me know.
PS. I sure hope it's not the processor fan, I really can't afford a new one if my CPU is fried.

In my opinion, there is a problem with power supply. There are two reason I think, the first one is the age of your computer. Is it too old? My computer run for 5 year and have a problem with power supply. I have to change the new one. The second one is the power voltage in your country. My country use 220V power change while japane use 110V power charge. Some of the product that my brother took from japan after his scholarship, could not use in my country it burn and have a smell like your computer too.
However, you should open your system case and try to run your computer. Make sure where the smell come from and identify the problem.

Hi
Once I too had a similar problem.
I opened the SMPS of my computer, to find a lizard inside, half cooked under the circuit boards.
So...go..take a plate, fork...and get ready...

I've been having trouble with a weird networking problem lately. Two computers (C and D in the diagram below) have "isolated" themselves and refuse to communicate with any computers besides each other, or access the internet, and they do not allow other computers to access them either. From what I can tell, there are no hardware problems that would stop them from being able to do so.
I have...
* Changed the network card on one of the two computers.
* Changed the network cable between router A and switch B.
* Attempted to release/renew the IP addresses of the computers, but they were unable to find a DHCP server on the network.
* Tried a different switch to replace switch B.
* Pinged internet sites and other computers, but the two computers can only ping each other.
* Checked the computers' basic network settings to ensure that they are correct.
* Plugged computer C into router A
* Reset all routers and switches by unplugging them for 5 mins.
... all to no avail. Anyone have an idea as to what's going on?

Check the router (C for DHCP Server running?
check Auto pc's DHCP?
check same subnet?
check same workgroup?

I gave both of the computers static IP addresses, and they worked correctly after that. However, I'd like to know what the cause is - does it indicate that my gateway router is going bad, perhaps?

Something weird seems to be going on with broadcasts. Typically gateways won't route broadcasts across their interfaces. DHCP clients use local broadcasts (255.255.255.255) to locate a DHCP server; ARP, the Address Resolution Protocol, uses Ethernet broadcasts on the local segment to locate IP hosts. Neither are routable.
If you have a router, rather than a level-2 device such as a switch, you must allocate different IP subnets to its various ports, and ensure that the subnet information is configured appropriately on each connected device. Otherwise the router simply won't route the packets to the right networks. You'll probably also need DNS or WINS for name resolution; Windows Browse is a broadcast protocol which isn't routable.
Another possibility which springs to mind is that the computers' network cards support software configuration of their Ethernet addresses, and they clash. This causes everything to go wrong, including the switches, which remember which MAC addresses belong to which ports so they can direct Ethernet packets to the correct port.
Stability. What an interesting concept. -- Chris Maunder

Hi I read "MCSE Training Kit Microsoft Windows 2000 Professional" in Chapter 2 "Installing Windows 2000 Professional" under "Lesson 3: Installing Windows 2000 over the Network". I have a problem in the following section:
Performing an Installation over the Network
The Windows 2000 Setup program copies the installation files to the target computer. After copying the installation files, Setup restarts the target computer. From this point on, you install Windows 2000 in the same way that you install from a CD-ROM.
The following steps describe the process for installing Windows 2000 over the network (see Figure 2.8):
On the target computer, boot from the network client.
Connect to the distribution server. After you start the network client on the target computer, connect to the shared folder on the distribution server that contains the Windows 2000 Professional installation files.
Run Winnt.exe or Winnt32.exe to start the Setup program. Use Winnet.exe for an installation using Windows 3.x on the source system, and use Winnet32.exe for an installation using Windows 95, 98, NT 4 (or NT 3.5), or 2000 on the source system. Winnt.exe and Winnt32.exe reside in the shared folder on the distribution server. When you run Winnt.exe from the shared folder, it does the following:
Creates the $Win_nt$.~ls temporary folder on the target computer.
Copies the Windows 2000 installation files from the shared folder on the distribution server to the $Win_nt$.~ls folder on the target computer.
Install Windows 2000. Setup restarts the target computer and begins installing Windows 2000.
Check under the section that I formatted with bold and italic. There are four command that describe in this book. I used to see the command winnt.exe and winnt32.exe, but now I get confuse when there are 2 more command (winnet.exe and winnet32.exe). Can anyone give me an idea about these two command?

Academic Learning Series Microsoft Windows 2000 Professional with Evaluation Software Comments And Corrections (Q304117)
Page 48: Misuse Of Words "source" And "target"
On page 48, under "Performing an installation over the Network", in item number 3 make the following corrections to the second sentence.
Change:
"Use Winnet.exe for an installation using Windows 3.X on the source system, and use Winnet32.exe for an installation using Windows 95, 98, NT 4 (or NT 3.4) or 2000 on the source system."
To:
"Use Winnt.exe for installation if you are using Windows 3.X on the target system, and use Winnt32.exe for installation if you are using Windows 95, 98, NT 4 (or NT 3.5) or 2000 on the target system."
Also note: winnet.exe and winnet32.exe should be winnt.exe and winnt32.exe.

Thanks I so that program.
Do you know where I can read to understand how to gather this information.
I need to incorpaorate that logic into an existing program.

Again, I didn't see in your first post you were trying to incorporate it into your program.
That actually would be a whole different subject; What platform, language, ect..ect..
If your on the .Net platform then you may want to start here.

I assume your Pluto26,
I didn't see in your first post you were trying to incorporate it into your program.

The utility I was refering to is PsList.
PsList
http://www.sysinternals.com/ntw2k/freeware/pslist.shtml
PsList works on Windows NT, Windows 2000 and Windows XP.
Usage
The default behavior of PsList is to show CPU-oriented information for all the processes that are currently running on the local system. The information listed for each process includes the time the process has executed, the amount of time the process has executed in kernel and user modes, and the amount of physical memory that the OS has assigned the process. Command-line switches allow you to view memory-oriented process information, thread statistics, or all three types of data.

Hi, I read the book about disk compression and I note that the book used to tell me about the advantage of feature in windows 2000. But I heard my friend and my teacher told me that disk compression has it advantage too. Its disadvantage is reduce the quality of our hard disk and make our hard disk easy to have bad sector and no function. Does any other people have an idea about this issue?
