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.

I looked it in c:\windows\security and in c:\windows\systeme32 But i did not find it.
Where the passwords stored.
Thanx indeed.

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?

Yes windows logon password.

On Xp they are in
WINDOWS\system32\config\SAM
WINDOWS\system32\config\system
No I won't tell you how to extract the passwords!

If I did that I would be flamed 
I was asked to break the password of a laptop, the owner had died, so I did some research, as a test I created a new account and password on my XP bix and managed to get the password.
But to give you a clue, I am sure you would find it eventually, use rainbowcrack http://www.antsight.com/zsl/rainbowcrack/
I think you will find it takes far too long to make the tables for this to be an easy soluion, but it is possible! Also you need to be able to get these two files to crack the password
BTW in the end breaking into the laptop was so easy I did not need to do the above.

Windows 95/98 used to store the password with some trivial encryption in a file in the windows directory, but anything later than that does not. As others have said, through the miracle of cryptographic hashing algorithms, it is not necessary to actually store a password in order to be able to verify it. Thus, NT/2000/XP/2003 only store password hashes, not actual passwords.

Good luck ...and i would appreciate if youw ill be able to help me :-

Hi,
Admistrator,in my office is very much willing to hack others system.I have Windows 2000 OS installed in my system.And I am sure that he does not know my login password so that he can hack my system through "Remote Desktop connection feature".Though some how he does.
Can u help giving ideas to protect my system.Atleast if I get a message when he tries to access my system will be appreciable.
Help me.

You can disable remote desktop and terminal services and all these things that allow any one to use your pc and log to it ,by setting the Services you want only , and also from the Local Security Policy ,they are really good and helpful ,i have modified them in my own system and it is doing good till now

I am not sure if this is qualified as 'hacking' really. After all, he is the system admin.
