A few things. It checks the directory structures to make sure there are no circular references, two files marked as being stored in the same location or similar errors like folders with files that do not exist. Basically for corrupted items in the main file system structures. This is normally checked quite quickly.
Then it moves on the the actually disc surfaces which are the individual hard disc platters. It scans each track on the platters for bad bits/bytes. Basically say it wants to right a bit as 1 rather than 0, but the actual disc surface is damaged/faulty though wear then it may try to write the element as a 1, but it remains as a 0. This could lead to bad data, so it can check for these, and remember to not use them in future.
Make sense? Check out the Storage Review reference section [New Window].
Hope this helps,

It also checks for lost clusters, which usually happen when an abnormal shutdown has occured. These are areas on the disk that are reported as occupied by files, but they're actually not associated with any files. They simply take up room on the HD - room that you cannot use for your own files - unless you get rid of those clusters using scandisk.
In some operating systems like Windows NT-based, lost clusters are reduced to a minimum by making sure that any IO operation, made by the system, must report its completion to the operating system, or it will be canceled and rolled-back at boot time.

Hi all,
I am trying to figure out if I can have a box with NTServer share my DSL connection to the rest of my computers. Basically, I have 5 static IP addresses but I have many more computers that need to be on the network and on the internet. So without having to buy more IP addresses, I figured I would ask here to see if the NTServer box can have the only Static IP address and have all the other computers share the internet and the network trough the NTServer box. Can someone please give me the steps on how to do this, or direct me to a wedsite that can guide me through it.
Thanks in advance.
P.S. I am new at all this network stuff, so any help is appreciated.

Yes that's possible.
There is a technique called NAT (Network Address Translation) which is implemented at the router level.
Basically what this does is that enables you to have one IP address visible on the Internet and have all other IP addresses private, so when a packet from outside comes into network your router will figure it out for what machine is destined. (i.e. address translation).
Whenever you go to access some external website, your IP will be the same, regardless of what machine you use.
This has the advantage as you can add much more machines to your intranet.

Venet.

Have you tried using MSProxy server on the server and MSProxy client on the workstations?

But, does that have limitations, in sense that each workstation will need to have its own public IP address, therefore need to buy more IP addresses?

No, each workstation will have a private address (192.168.0.x) and the server will have the only public address. Or at least this is how we used it then.

I always thought Address Translation from Public IP to a private one (10.x.x.x or 192.168.x.x) is done at the router level, not at the application level.
Do you have a router as well on your network that does address translation?

Venet.

A computer used for internet connection sharing acts as a router (and does NAT).

Yeah, but with NAT-ing TCP (and IP AFAIK) headers need to be changed.
I know this can be done in linux, but considering Windows doesn't have full support for raw sockets, I thought it cannot be done.

Venet.

Forget the NT box. Sorry, but Windows and IP is not something you can get anything reasonably good out of without a larger amount of cash.
Get an old machine (and here we're talking 486 level - something you wouldn't dream installing anything MS on nowadays) and install some *nix/*BSD to let it act as both a firewall and NATing gateway.
I actually have seen an NT5 (aka "Windows 2000" for the marketing droids) Server act as a HTTP and FTP proxy. Once. However, no one apparently had a clue of how it actually worked, and just the idea of blocking or opening stateful connections for other ports met with a blank stare.
It's your choice, but I'd personally never even try to use a Windows machine (no matter what version) as a 'net gateway.
You don't try to get a DC-3 to get fly faster than the speed of sound - it's just not healthy.

Yep.
Windows doesn't have even have a proper TCP/IP stack implementation (raw sockets for example).
I have SuSE linux that I use as a firewall and it's not too hard to set it up.
So the best is to go with linux.

Hi,
First of all, you cannot get system information remotely from a machine running Win 9x, unless of course you have some third party application installed on it.
This is possible in Wi2k, and there are some utilities from the Win2k rescource kit, however I cannot remember the exact name of the utility.
Look into ResKit CD, if you have one.
Regards,
Venet.

Does anyone know of some boot manager software that I can use for the following configuration:
- Hard Drive #1 - Windows XP Professional
- Hard Drive #2 - Windows 2000 Advanced Server
I have both drives in one computer and would like to have an option of which OS to load when I start up. I know there are boot managers out there to control this when two OS's are loaded to one hard drive with multiple partitions. These are going to be completely separate drives. Any ideas? Thanks in advance.

No need to use third party software. Windows has a native support for dual booting between MS OS-es..
Just install Windows 2000 first and then install Windows 2000 Advanced Server. Changes should be made so as to choose what OS to load up.
It's very easy to do it manually as well.
All you need to do is modify boot.ini file.
Thanks,
Venet.

I haven't checked Windows 2000 Advanced Server yet, but just did on Windows XP Professional and it does not have a boot.ini file.

Right Click on My Computer > Properties > Advanced > Startup & Recovery. *
There is a combo box displaying the current OSs on the system. From this page you can select the default and edit the boot.ini file. (If there is not one, it will create it for you)
* This is on Win2K and WinXP only

Thanks for the tip, my boot.ini file looks like this:
[boot loader]
timeout=30
default=multi(1)disk(1)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
Do you know how it should look with Windows 2000 Advanced Server listed as an entirely separate drive within this file? Thanks again.

Contents of boot.ini should be changed automatically when installing another microsoft OS, so you shouldn't really need to worry about it.
But it should look something like this:
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
multi(0)disk(1)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Advanced Server" /fastdetect
You can change it to say anything you want though.
There is another way to make a machine dual boot, by copying first 512 bits (boot sector) of the harddisk/partition that has Win2k AS, but that's a bit complicated really.

Venet.

Is there a way to set up DNS on a Windows XP Professional computer? I have bought a domain, and would like to run the site, which is done in ASP.NET, on my computer. Does anyone have any ideas or helpful hints? Thanks in advance.

Do you have a fixed IP address?

Well, my answer to that is that the cable modem that I have uses DHCP to asign the IP, however, my IP address itself has never changed, so it appears to be acting as if it were static. Any ideas?
