Why does 'Error 1068 The Dependency Service or Group Failed To Start' appear when starting the remote access auto connection manager or print spooler in Windows XP?

Best answer is that the registry is corrupted you can do the steps on this page if you can get it to work. Another way is to just download a default services reg file. It will definitely fix your problem, however you may have to reload some programs or reactivate some needed services. It will also speed up your computer processing. You can go to and check out the downloads section for your Windows build or go to Windows Support website and check their downloads section for a similar file. This will save you time and headache of trying to get the program (or whole system in my case) to work with no result.

Make sure Network DDE and Network DDE DSDM are started in Services. You can get to services by going to Start, Run and typing Services.MSC

What is Linux?

Linux is a free, open source operating system kernel, but now is considered to be packaged with other programs to be an entire operating system (known as a distribution, as there are different ones). It is similar to the Unix operating system which has been around for decades.

Red Hat and Ubuntu are two examples of Linux distributions -- others include Debian, Suse, Mandrake (formerly Mandriva), and more. Linux as a whole is known for its robustness; it's used in mission-critical tasks by many industries. It can cost little to nothing to download and install, or you may choose to have a vendor pre-configure and provide support for you.

By far, the two most popular distributions are Ubuntu and Fedora.

How do you zero out a hard drive?

If you mean "completely erase" it, the term is "Format" and you can perform it from DOS using the command "Format c:".

I think it is beyond formatting. I read today in the New York Times that John Jay College in NYC has adopted a program that covers the free space with zeroes.

The program your probably talking about is This program erases all forensic evidence that remains on your hard drive after you format it, and believe you me it's alot. You can recover the entire contents of a formatted hard drive with the right tools. But EE prvents this and effectively "Zero's Out" you hard drive.

Formating a hard drive prepares it for use and deletes previous file names so Windows can't see them. They still exist and can be recovered with several Undelete programs. However, if you wish to remove all data from the drive, just formatting is not enough. "Zeroing" a drive rewrites over the entire drive, replacing previous data with simple 0's. There are several 'Zero' filling programs available on the web and some drive manufacturers include a zero utility on their support sites.The previous answer is pretty good, however it is argued that you can recover a zeroed hard drive. It is possible to retrieve "some" data however "fully recovering" a zeroed hard drive hasn't been done as far as i know.simply doing a "1 zero pass" will invert all the "1's" to "0's" (remember there are only 1's and 0's) hence "zeroing" however there is software available that can detect newly magnetized "0's" it simply re-inverts the "0's" to "1's" if you do a "7 zero pass" it's pretty much impossible to retrieve any information off the hard drive. look into the "DoD 5220.22-m" standard or "gutmann".hope this is useful.

What are the features of Linux?

Linux has evolved to have the following features as an outstanding operating system which is strong in security and networking.

• Multitasking: Several programs can run at the same time.

•Multiuser: Several users can logon to the same machine at the same time There is no need to have separate user licenses.

• Multiplatform: Linux runs on many different CPUs, that means it supports multiprocessor machine.

• Multithreading: Linux has native kernel support for multiple independent threads of control within a single process memory space.

•Crash proof: Linux has memory protection between processes, so that one program can't bring the whole system down.

•Demand loads executables: Linux only reads from those parts of a program that are actually used on the disk.

•Shared copy-on-write pages among executables: This means that multiple processes can use the same memory to run in. When one tries to write to that memory, that page (with 4KB piece of memory) is copied somewhere else. Copy-on-write has two benefits: increasing speed and decreasing memory use.

• Virtual memory uses paging (not swapping whole processes) to disk to a separate partition or a file in the file system, or both, with the possibility of adding more swapping areas during runtime (yes, they're still called swapping areas). A total of 16 of these 128 MB (2GB in recent kernels) swapping areas can be used at the same time, for a theoretical total of 2 GB of usable swap space. It is simple to increase this if necessary, by changing a few lines of source code.

•Linux has a unified memory pool for user programs and disk cache, so that all free memory can be used for caching, and the cache can be reduced when running large programs.

• Linux does core dumps for post-mortem analysis, allowing the use of a debugger on a program not only while it is running but also after it has crashed.

• Linux is mostly compatible with POSIX, System V, and BSD at the source level.

• Through an iBCS2-compliant emulation module, Linux is mostly compatible with SCO, SVR3, and SVR4 at the binary level.

• Free and Open source code for all: All source code of Linux is available, including the whole kernel and all drivers, the development tools and all user programs; also, all of it is freely distributable. Plenty of commercial programs are being provided for Linux without source, but everything that has been free, including the entire base operating system, is still free.

• Linux supports pseudoterminals (pty's) and multiple virtual consoles: By several independent login sessions through the console, you can switch between by pressing a hot-key combination (not dependent on video hardware). These are dynamically allocated; you can use up to 64.

• Linux supports several common file systems, including minix, Xenix, and all the common system V file systems, and has an advanced file system of its own, which offers file systems of up to 4 TB, and names up to 255 characters long.

• Linux has a transparent access to MS-DOS partitions (or OS/2 FAT partitions) via a special file system:.You don't need any special commands to use the MS-DOS partition, it looks just like a normal Unix file system (except for funny restrictions on file names, permissions, and so on). MS-DOS 6 compressed partitions do not work at this time without a patch (dmsdosfs). Also VFAT (WNT, Windows 95) support and FAT-32 is available in Linux 2.0

• Linux has CD-ROM file system which reads all standard formats of CD-ROMs.

• Linux performs well with TCP/IP networking, including ftp, telnet, NFS, etc.

• Linux is userfriendly as Netware client and server

• Linux also runs as Lan Manager/Windows Native (SMB) client and server

• It integrates many networking protocols: The base protocols available in the latest development kernels include TCP, IPv4, IPv6, AX.25, X.25, IPX, DDP (Appletalk), Netrom, and others. Stable network protocols included in the stable kernels currently include TCP, IPv4, IPX, DDP, and AX.25.

What are Linux commands?

Linux commands are commands entered into a Linux terminal (command line interface) and it performs accordingly. For example: if you entered 'pwd' into the terminal prompt and pressed ENTER it would return the current working directory be it /home or /etc

'ls' will list all files and directories the specified directory. If no directory is given, the current one will be used as default.

the best way to learn Linux commands is to try them out for yourself which you can via installing Linux or downloading a live Linux CD, booting into it and type in different commands (as a normal, non-root user -- root has all kinds of super-duper powers and can break things easily).

AnswerIn fact, the 'commands' are programs. They can be stored in different directories, usually:




For example, when you type 'date' into a command line, the program /bin/date is launched. Programs in Linux don't usually have .exe in name. This program prints current date on users screen.




just type:

which command

at the prompt where command is what you are searching for and the Linux style computer will tell you.

i.e. :

%which CD


CD: /usr/bin/CD /usr/share/man/man1/CD.1.gz

so it says that the command CD is at /usr/bin and the manual is at /usr/share/man/man1.

There are many different commands available in Linux. Some of the most basic are:

  • ls - lists the contents of a directory
  • dir - same as above but with escaped spaces
  • mv - move a file
  • rm - delete a file (semi-permanent)
  • cat - reads a file
  • less - used to pipe lengthy output from a command so that it can be scrolled through. Use like ls | less.
  • cp - copy files. cp file1 file1copy
  • grep - search for text in a file. Can also be used to search for words in a command output. Example: ls | grep partoffilename

Should real time operating system be necessarily multiprogrammed?

MULTIPROGRAMING .................. The term multiprograming denotes an operating system that,in addtion to supporting multitasking. In multiprograming more than one jobs are active in memory.Within a very small period more than one jobs are executed simultaneously. MULTITASKING ............... In general multiprogramming implies multitasking,but multitasking does not imply multiprogramming. A multitasking operating system is distinguished by its ability to support concurrent execution of two or more active processes. as discussed actually both multitasking and multiprogramming are same no other answer mentioned are justifiable.....

What is ldlinux.sys?

ldlinux.sys is the name of the bootloader file used in SYSLINUX and ISOLINUX (used for booting Linux off of FAT32 and ISO9660 filesystems, respectively). It is loaded into memory by the BIOS on bootup. The loader then parses the configuration file (syslinux.cfg or isolinux.cfg) to know which kernel to launch, along with parameters to be passed to it.

What are the features of real time operating system RTOS?

RTOS is a real time operating system.The important features are :- - The necessary signalling functions between interrupt routines and taskcodes are handled by RTOS. - It works as an independent system with no internal or external interdependencies. - There are no loop descisions in RTOS - The RTOS can suspend one task code subroutine in the middle order to run another - The time lag is veryless compared to other systems - There are no random time variables, this is good for a direct relationship between instruction and process. - Tasks are simpler to write. - Under most RTOS tasks are simply subroutines.

What is the developmental trend of Linux?

Linux in itself, that is, the core OS is being developed with more stability, security and support for devices and software in mind.

Nevertheless, the Linux distributions (or distros) are modeled Linux kernels to fit specific needs and they each have a different trend. They all use the Linux kernel in the core, but the uses and abilities can vary greatly.

Check out the different distros and choose one you like. If you are disappointed or don't like it, don't worry, choose another flavor and download, theyre all mostly free.

How do you play DVDs on Fedora 10?

You can use the Totem player that is preinstalled for this.

However, you cannot play DVD's encrypted with CSS (Content Scrambling System). CSS is used by the movie studios as copy protection measure.

Any version of Linux is quite able to read and unscramble the disc, but the software (called DeCSS) typically used is an unlicensed descrambler. It could be considered an offense to obtain or use an unlicensed descrambler in countries that are parties to certain international copyright and intellectual property treaties, so you should consult with your legal counsel.

Fedora 10 does not include one for this reason, but you can obtain it from another repository such as Livna. A company called Fluendo is working on one that is expected to be certified.

Which Linux distribution would be the best for an acer laptop from the perspective of ease of use drivers support and packages for development fedora freespire or pclinuxos?

Freespire is arguably the easiest one to install packages on, though I dislike certain aspects of "CNR." It also allows (or did allow) the easy installation of proprietary drivers, which most distributions do not include by default. PCLinuxOS has an all-around nicer interface, and better tools for configuring the system. Fedora is more traditional, and styled similarly to Red Hat Linux. Though I seldom find any distro "difficult" to use, Fedora, is probably not the best choice for a novice user.

What is the tilde used for?

A diacritical mark (˜) placed over the letter n in Spanish to indicate the palatal nasal sound (ny), as in cañon, or over a vowel in Portuguese to indicate nasalization, as in lã, pão.

A symbol used in Windows, starting with Windows 95, that maintains a short version of a long file or directory name for compatibility with Windows 3.1 and DOS. For example, the short version of a file named "Letter to Joe" would be LETTER~1. Then "Letter to Pat" becomes LETTER~2. In the Unix world, all the popular Unix shells (except for the Bourne shell) support a home directory name substitution using the tilde. Also called a "squiggle" or "twiddle," the symbol is used as a prefix to a user login name to specify that user's home directory. For example, if your user name were "jackson," you would use ~jackson to refer to your home directory. The tilde symbol is a Spanish accent that turns the letter "n" into a "nyeh" sound such as in the word mañana, which is pronounced "mah-nyah-nah" and means "morning" or "tomorrow." The tilde is also used as a mathematical symbol that means the difference between two values or an equivalency between two values. The tilde can also be used as an abbreviation to indicate approximation. ~50 = "approximately 50." It is technically supposed to be two tildes, one over the other, but it has become common to simply use the one symbol. Also, the tilde is used in Symbolic Logic to indicate a "not" value. ~A = "not A." A --> ~B = "If A, then not B"

How do you install Fedora?

Actually, it's not that different from Windows installation. If you have windows you have to prepare place for Fedora. For that resize your hardrive(s) in the way to have enough space for fedora. After this process you will have unlocated space which you are going to use for Fedora. After that just restart your system and boot from Fedora CD/DVD (network and so on...) Just follow instractions. If you are not interested in advance installation just choose graphic mode. Usually you don't need to help system to change partions, but sometimes it's necessary.If you want install just Fedora then boot up from Fedora disk and press F5 when it's showing such options. You will start working in Rescue regime. To format hard drive(s) use commant fdisk with parameters. For example: fdisk /dev/hda. Them you will see - Command (for help press m):... What each parameter does is described in there. (If you have one of RAIDs you have to use different procedure).
