How can i secure my binary files from being edited/corrupted by unauthorized persons?
Reply:
edited means that it is done for *some* purpose. Corrupted implies that it was a machine failure.
Backup files in a secure medium of the main server is the first step. 2nd step would be to encrypt the files after *you* have edited them with a passcode. There are many tools to do this part. 3rd thing is to have a Source Code control mechanisim to Verify and authenticate the changes.
Ie version 1 begets child document 1.1 that then gets Child document 1.1.1, and so on until you get to the level of changes you want.
Change a whole paragraph, now you are at document level 1.2 etc.
Revise the Document 3 chapters at a time, Now the version is 2.0.0 etc.
Its a matter of how much effort you wish to do now , as opposed to how much effort you want to do later.
An example of a windows tool to use is WinZip, use it Zip the files to Hard drive in the directory , and turn 128 bit encryption on. then save the files to the server.(remember your password & Dont write it down. REMEMBER it. Try a few sample ones you may dream up. write them down on a post it not in your journal. Don't look at the note for 1 month. See how many you remeber after 30 days? this telly you how good your memory is, now think how hard it will be if you forget a file and dont remember the password for 12 months.
what a pain. Remember. it all depends on how much work you want to do now as opposed to later, (possibly when you forget what the password was).

hi,
I want to enumeratie all the users and groups of my xp. I solved this by using ADSI (Winnt://).
Here is my question:
What underlying local system does the ADSI WinNT Provider use to enumerate all the users and groups as I do not have a directory service somewhere?
I looked through LSA but could not find anything here. NetLan Management just returns the public accounts but not the build-in accounts.
Thanks for any help.

Hi,
Anybody knows about software modems. Or any helpful links to know about?
Actually my objective is to test the (already present)software modem in
my system. Diagnostics purpose.
Thanks

What do you want to know from here? What do you mean by software modem? You mean a driver of the modem? I don't understand about your question. If possible, please explain more detail about your question again.

3 times in the last 2 months, I've had problems with the data on my main hard drive becoming partially corrupt.
The first time it happened, the computer froze up totally, with the hard drive light on steady. I reset the computer, and when it started up again, I got a BSOD, with the error being "UNMOUNTABLE_BOOT_DEVICE". I booted from my PEBuilder CD and tried to access the drive, and I got an "Error while performing InPage operation" error, and the drive's contents would not show up. I put the drive in another computer, and ran CHKDSK on it, and it found a number of corrupt folder and file entries, which it repaired. I could boot from the drive after that, but I decided to get another drive and copy the contents over to it rather than risking further problems with the original drive. I also replaced the IDE cable.
It worked for a little while, but then a few weeks later, there was a BSOD, with a "IRQL_LESS_OR_EQUAL" error (IIRC), and when the computer rebooted, CHKDSK found corrupt file system entries again. The system booted correctly, but I decided to replace the mainboard to see if that was the problem, as I'd been seeing "IDE1 no 80-conductor cable detected" even though there was indeed an 80-conductor cable, so I figured something might be wrong there. Did a repair install of Windows so that the drivers would be re-detected.
Since the first time it happened, I've been getting various BSODs from device drivers - FASTFAT.SYS, NDIS.SYS, etc. (I have pictures of several of them if that would help). Then today, my computer rebooted itself while I was out (probably after another BSOD), and a whole bunch of invalid indexes were corrected, and a bunch of orphaned files were recovered. The computer booted, but many programs cannot load DLLs (they have "Bad Image" errors), and I can't launch any programs via shortcuts, the Run menu, or Explorer - only programs that are set to start via the registry start up. Task Manager doesn't work, I can't open the Event Viewer snap-in, etc.
I'd say there's nothing for it but to reinstall Windows completely. But the reason why I've written this post is that I worry that there may still be some hardware issue that's causing this (power supply? RAM?). So my question is, is this likely to be caused merely by a corrupt Windows installation, or should I suspect a hardware problem?
Here's some info on my system that may be helpful:
Power issues:
Have surge suppressor
Another computer that is on the same surge suppressor does not have any of these problems
Mainboard/CPU specs:
Althon XP 2000+ on Gigabyte 2004RZ mainboard, formerly on ECS EliteGroup K7VTA
Normal operating temps: Sys: 31C/87F, CPU: 50C/112F
RAM:
Kingston DDR @166MHZ
2 256MB modules
memtest run through 6 passes, reports no errors
PSU:
300W
came with case ( = good chance it's shoddy?)
BIOS voltage monitor reports correct voltages
Thanks so much in advance for any help!

I would have said RAM faults, but memtest passes it. You could try Microsoft's Windows Memory Diagnostic[^].
Check that your hard drive cables are seated correctly and aren't damaged. Ensure that you're using the right sort of cable - I'd now recommend that all IDE/parallel-ATA cables are of the 80-way type. Saving a few pennies on 40-way cables is a false economy, IMO.
Since you had an 80-way cable that wasn't being detected, it's quite possible that the data on the disk has become corrupted. In that case you probably will need to reinstall.
If any component is overclocked, revert it to its correct clock speed. See Raymond Chen's post on overclocking[^] for details on the problems this can cause. If your new motherboard has 'dynamic overclocking' features turn them off.
Problems could also be caused by either faulty drivers or faulty add-in hardware. Remove every non-essential card and connected device, and see if the problems go away. If they do, add devices one at a time until the problem resurfaces. Look for an updated driver for the device you added last, or replace the device.

Thanks for the link - I may try that as well.

After the first time this happened, I replaced IDE the cable with the brand new one (80-conductor) that came with the new drive, and took extra pains to be absolutely sure it was seated right.

Nothing overclocked.

I have 2 cards connected - a NIC and an AGP graphics card. I have a graphics card of the same model in a different computer, and haven't had any problems with it, although it could perhaps be a problem with this particular card. When I changed the mainboard (the 2nd time the problem occurred), I used an alternate NIC just in case.
I have 2 USB peripherals (other than my keyboard and mouse) that were connected during at least one crash - a USB wireless NIC, and a memory card reader. The NIC was connected the 2nd and 3rd time but not the 1st. The card reader was connected the 1st and 2nd time but not the 3rd.
When I did a repair install of Windows after replacing the mainboard, it should have wiped out any bad drivers, so unless the drivers on one of the CDs were bad, or some drivers stayed in the driver database, I don't think it would be a driver problem.
Thanks for your help!

I had soem really dodgy HD problems liek this and it turned out to be related to heat.
I was running 2 IBM 200GB drives in my case with only about .25 inches between them and mounted sideways (really stupid case design) tot he cases air flow. Both drives would go bad after about 20 hours of use. Just enough to get windows installed and have them sit overnight. Once bad the drives would not boot any more nor would they get detected. A few times I had them boot and then the machine just would reboot on it's own or lock up.
I used a thermometer on the new drives I got and watched them run idle @ around 90c. The drives themselves weer rated gfor an upper op temp of 110c. Once the drives were under use they temps rose to just around the upper limit.
I ended up getting a set of fans to mount right on the drives to keep them cool (down to around 65c) under use, changed my case to allow for better airflow, and never had a problem again.

How can you tell the number of parallel ports a PC has and the address of each.
Are they a test program?
I can find info on LPT1 via the device manage, but as only one show is that the only parallel port on this PC?
I can read 255 for both LPT2/3 but are they there?

hi
I tried to play some files in a Media( CD )using a VC++ application.
The very first time, it takes considerable time to access the large files. But the next time onwards its very fast. And I seemed, OS not accessing the Media for that file in the later times.
When I eject the CD and again insert.Now its takes time for the 1st access
Can U please say what is the logic behind it?
Thanks in advance

This is normal cacheing behavior. The file is cached in memory, which is much much faster than a CD drive. When you eject the CD, the cached files are discarded because the original files become inaccessible.

Whether its not accessing the Media from the second time onwards?
The Media is not rotaing while acessing from the second time.

Hello i am using windows XP as administrator. The problem is that the exploerer does not save the pages offline. That is you can view them offline. I have tried the method told in the "f1" help to synchronize the web pages before offline but i do not like it and it sometimes does not work.
Is there any way the exploer behave as in windows 98 and 2000 where u can see previous webpages by going to histroy .
Is there some problem with installation?
Plz help me out

I have to convert a program written for linux to windows. I am a complete novice in this field and require some help. The current code involves system level programming and uses a large number of linux header files including
module.h, moduleparam.h, kernel.h, fs.h ..
Are there any suggestions as to what would be a good starting point for such a conversion? Also, what would be a good resource to find windows equivalents to for these header files?
Thank you very much!
|

It sounds like you're trying to convert a kernel-loadable module. The closest Windows equivalent is a device driver: to develop one, you'll need the Driver Development Kit[^]. You aren't going to be able to port the code - you'll need to do a complete rewrite. By my understanding, the Linux kernel development model is very different from the Windows driver model.
What are you actually trying to achieve? Windows may provide a facility to achieve this in user-mode code.

Ask yourself what would happen if account passwords were kept somewhere. Would you want any old program (like, say, a virus or spyware) to be able to read your passwords?
