Press CTRL+ALT+DEL and start the Taskmanager.
In the Taskmanager, start a new tast and type in explorer.exe.
This should bring up your desktop.
When desktop is started, check the event log for errors, to figure out, why explorer.exe gets not started automatically.

And this happens also in safe mode?

Maybe the computer is infected by a virus.
If you can gain access to the windows drives by using a live cd, I would suggest to check, whether the explorer.exe has the same length as the explorer.exe from the original CD or the service pack, that may be already installed.

What I meant is, that the explorer.exe file may have been infected by a virus.
So if you can compare this file with the original file, that comes from the windows CD.

If you have installed service packs for windows, the original explorer.exe may have been substituted with a newer one of the service pack.
In that case, you have to compare the explorer.exe from your installed windows with the explorer.exe, comming with the installed service pack.

Another solution may be, to use a live cd, to scan your hard drive for viruses.
Avira offers a free live cd to manage this.
You can download the "Avira AntiVir Rescue System" ISO image here:
http://dlpro.antivir.com/package/re...

Burn this on CD and start your pc from this CD.

It's normally located in \windows folder

If possible, compare also the content of the file.
If you have e.g. TotalCommander, it has the option to compare 2 files by contend.

Because it's a compressed file and named explorer.ex_.
Copy this to your pc into a temp folder and extract it.
After that, it's named explorer.exe.

Can you boot OK into safe-mode?

Have you reduced RAM to a single stick and tried each in turn if more than one installed? Min = 128Meg for W2K...

Do you have a Linux on CD variant - Knoppix or Ubuntu being the usual two?

If so... boot up with that; and then go on-line and run a freebie on-line virus scan - Trend Housecall is a freebie...

If you can boot with the above CD then first it would be wise to copy off all data etc. to optical media - and verify they play etc. OK on at least one other system.

Then do the on-line scan.

After that if problem persists.. consider a repair installation of OS? Having copied off all data etc. first of course as immediately above

Now I would recommed, to scan the whole system for viruses and trojans.
Best is to use something like I posted in "Response 8", because it's linux based and easy to use, and if there is any virus or trojan, it will not get started.

No.
Norton isn't the best choice since a few years.
Many free antivirus tools are better then Norton and didn't slow down the pc as heavy as Norton does.

Btw.: Norton might already be infected too.
The CD I recommand, can not get infected, gets updated in a RAM-disk and windows viruses do also not run on linux.

So all in all, it's worth to try.
I have alway an actual CD ot this, because, now my system is running, but who knows, what happens tomorrow.

Whenever you do get the system running OK again... suggest you resort to using Avast as a virus util (avast.com); freebie that does what it says on the tin...

Norton is a resource hogger by all acounts; rather bloated etc. Whereas Avast and one or two other freebies do an excellent job with non of the issues that surround Norton etc...

If you boot with a Linux CD(OS on a CD/DVD) and then go on-line you can easily run a "full" scan that way. No need to install or even attempt to install another virus util to do a full scan...

"When" system is OK again the consider a virus util as immediately above...

First// make a new ERD; keept handy - just in-case.

Then edit boot.ini so that it looks as follows:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows 2000 Professional" /fastdetect

In other words - delete the last entry "only".

(To find and edit the boot.ini: g via MyComputer\Properties\Advanced-tab\startup and r recovery\Settings - Edit button...)

Reboot system to ensure/verify you still can (just in-case you inadvertently deleted the wrong entry).

Once back up OK open Explorer - locate and delete the folder "winnt". That is the original installation folder...

When W2K goes in it "usually" calls itself winnt if that name isn't already in use in "that" partition. A second installation to the "same" partition will be called windows.... If there are two or more installations of W2K, each in a separate partition. then each will be called winnt... (unless in any situation/installation "you" choose to change the default folder name proffered at time of a given installation).

Empty Recycle-bin; defrag drive; reboot; renew ERD and keep safe.

Job dun...

Stay within the forum; that way everyone who reads this post gets the benefit; and also others may offer help as best they feel able...

Clarify/confirm...

You get the same problem in both modes; and you have not yet managed to edit the boot.ini - is that correct?

Did you do a full virus-scan (on-line) as advised earlier - either with Linux on CD boot - or when the OS installed second time was OK?

Also... have you two or more sticks of RAM installed? If so reduce to one only - min = 128Meg for W2K. Try each in turn... It "may" be RAM issue...; but then again it may not...

ERD is the Emergency Repair Disk. NT4, W2K, and XP have this facility... When you have working system... you make this disk as soon as you can. It allows you repair a system that will not boot properly for various reasons (but not all reasons that may cause a system to fail to boot properly...) It is copy of critical information - and it is strongly recommended to have this disk for any NT, W2K, XP system (not sure about Vista if it exists there too - never really messed with Vista...). Sasdl many these days fail to do this...

At this stage of events I'd be much inclined to do a repair installation of W2K... For etailed how to go about it read the following links; saves me going thru it all here; and these guys do it well...

http://www.windowsnetworking.com/kb...

http://msdn.microsoft.com/en-us/lib...

I would opt for the fast reapir option as it does all the manual does and a bit more (I htink).

Also if you asked which version to "fix/repair" ensure you choose the second one - which is (or was) installed as "windows" - not winnt... (winnt was the first installation - and is the one you were to delete from the drive and also its references in the boot.ini...)

Presuming you do get things running OK again... make an ERD... If not sure how to do this... use the W2K help files; as they will take you through it and include suitable hyper-links/steps to help you thru' the process... Keep it safe; and update whenever you make changes to the system (install anything, add new hardware, RAM etc...)

Not aware of avast - ever - causing problems; but always a first time I guess. I do know (from personal experience and also others have reported similarly with different OS - that avg has given some problems - ME was the OS at the time for me).

I had to repair (actually a parallel installation to get that system working... and then used avast (with no problems whatsoever...).

As in my previous/last post, I would go the repair routine I suggested; as that will resolve any duff/damaged files etc... and may thus allow you back in... If a system won't load properly then it's often due to damages files; dodgy RAM; or even a dodgy (as in bad sectors) hard drive... RAM is not uncommon - can you borrow a known good stick (min 128Meg and correct for your system) to test out?

I would also encourage you to poer down the system; remove the mains in plug/connection too. Then reseat "all" chips properly; and also verify that cooling fans are working properly when you power up again - especially the cpu...

When you remove RAM to reseat it... first clean its contacts with a sott pencil eraser, then reinsert/reseat... That has been found on occasion to resolve assorted issues not dissimilar to yours.. (That's a tip from others here.)

Incidentally - what file format is the drive at present?

Good to hear... I strongly advise you run a regular virus scan both avast locallly; and also a freebie (Trend Housecall) on-line.

Also maybe install and keep updated SypBot S&D and also AdAware... Both are freebies - but one does appreciate a donation occasionally I think...

AdAware - http://www.lavasoft.com/

SpyBot S&D - http://www.safer-networking.org/ind...

And again: make and keep up to date the ERD...

Also consider making a true restorable/backup set of disks so that you can restore the current working system if needs be that way? Acronis would good for this and is good util to have around... Often a deal for it on Amazon, NewEgg etc...

Finally regularly back up (as in copy) all data etc to optical-media; and verify those copies are OK on at least one other system...Again to ensure data at least is "usualy" safe...?

And yet again.. at this stage make data security/recovery your prime concern. Using Linux CD transfer all data of the system entirely. Do if now...

When you ran the on-line scan... (you did do one didn't you) did it quarantine anything it found? If so - locate and delete "anything in the quarantine folder. Obviously you use the Linux CD for the scan.

Presuming you can then again boot OK, run another local and on-line scan. Again watch for anything "quarantine. IF there is "anything" quarantined... as above, locate/delete it...

If the worst case scenario cometh to passe.. you may have to wipe the system entirely (reformat); then re-install OS etc.. Then scan all data files/disks - before returning any copies of data to drive...

The above is your "the ship is holed below the waterline and have to beach it for repairs" routine....

Meanwhile... which account(s) will not let you "log-on" and is this to get into the OS/desktop or what? Which account requires a password (avast)? I have not ever had to provide a password for avast (freebie edition); what are you using?

If you run a repair routine as suggested in an earlier post... what happens? Also have you again tried safe-mode option again at this time?

Not used recent (2002 is recent?) versions of Ghost; but know the earlier versions (V-8x) were OK... I use Acronis mainly as it's OK with XP etc...

If you've got Ghost and already you're au-fait with it... why not use it; but remember to ensure you make the requisite boot-disk too, or ensure your image is a bootable CD/DVD?

Regardless a restorable image (as in bootable one way or t'other ) is a good route to go. Likewise the data protection aspect (optical copies etc.) too...
